Dark 1: About Darkwards

1.1: Darkwards intro

I am a spirit of darkness named Darkwards, I go to dark places at night.



The definition of darkwards is: towards darkness, to be truly devoted to the night and darkness, and is suitably pronounced "dark-woods". The background photo here was taken during the April new moon at about 3am. This page is for exploring darkwards topics in depth and darkness. Like the universe, this page is constantly expanding; additional topics to be added here as I think of them... or do you have any ideas? If so, let me know!

1.2: No fear in the dark woods

One of the most common questions I get asked is: are the woods at night scary?



The answer is: it depends on why you think it should be scary, is it rational or irrational? I find the dark empty woods is a fantastic way to immerse yourself in nature while disconnecting from all the light and noise of everyday life. I do not get lost and my area is quite safe from aggressive wildlife. It is important to consider safety before you go anywhere, but logically, the woods at night is often no more dangerous (and arguably less so) than it is in daylight.

1.3: Living by the darkwards code

If you haven't already, you can read the fun darkwards code, which consists of 7 codes that define the darkwards lifestyle.



The only code that I don't follow is Darkwards Code #7: Follow Darkwards666 on Instagram, because I do not follow myself. I follow the other 6 codes very sincerely in my daily life out of love for darkness, but it's not rigid like religious dogma. You can be truly devoted to darkness and adaptable at the same time.

1.4: Darkwards' favourite music

This is answered in Darkwards Code #4: Listen to dark music.

Favourite bands:
Darkspace, Darkseed, Darkcell, Dark Tranquility, Dark Oath, Dark Funeral, Dark Fortress, Darkest Horizon, Dark the Suns, Spell of Dark, Dark Forest, Black Forest, Black Therapy, Nightcreepers, Nightland, Nightwish, Beast in Black, Twilight Force, Midnight Eternal, Midnight Odyssey, Midnight Realm, Moonlight Sorcery, Sunless Rise, Swallow the Sun, Obsidian Gate, Starforger, Ghostheart Nebula, Nebula Orionis, Astrophobos, Duskmourn, Nyktophobia, Insomnium, Woods of Desolation, Cryptic Wintermoon, Wintersun, Suotana, Eternal Tears of Sorrow, Evilfeast, Battle Dagorath, Dimmu Borgir

1.5: Random facts about me

I have two black cats, I like dark orange chocolate and my favourite drink is black coffee. I have a fear of some spiders, and I overcome it at night by turning the lights off.

Dark 2: Deeper, Darker

2.1: Stars, moonlit forests, belief

I sense great powers from the night sky full of stars, or the empty moonlit woods, but who knows what they really are.



I love to see followers of darkness share their spiritual path, especially when it comes from forests or stars. Organized worship is your choice, in my case church didn't work... but nature and darkness did. To believe or not is ultimately to not know; belief and disbelief are just positive and negative ends of the same spectrum of not knowing. To admit not knowing is a strength not a weakness. The only thing I do know is that the cosmos is amazing.

2.2: Existence: the inevitable end

It can be premature or delayed, feared or desired, gradual or sudden, natural or inflicted, painful or painless, happy or tragic... but it is always certain: the inevitable end. 🪦



The inevitable end of not just life, but of every creation, every situation, every relationship etc. Every full moon, every spectacular sunset, every night sky event; they are all reminders of the passage of time, every one of them could be the last one for anyone. Compared to pure nature and forests, the cemetery is also a powerful atmosphere while offering a different, more intense experience, with more emphasis on connecting with finality. With acknowledgement of death and impermanence comes appreciation for what life offers, and preparation to reduce the devastating effects of tragic but inevitable losses.

2.3: Darkness is everywhere

This section is related to Darkwards Code #6: Keep others in darkness.



It does feel safer and more liberating to maintain some element of mystery, to embrace darkness not just in the woods but in every-day life too. For me to suggest going against our own nature too much would go against the spirit of having an entire page dedicated to nature. However, as social beings, one problem is that our materialistic standards are based on social comparisons - if everyone around us appears to have more and be doing better, we feel inadequate. Similarly, if everyone around us appears to be doing worse, we feel good about ourselves.

A common result of our comparative nature is that we bring others down to bring ourselves up, which is not a healthy mindset to have and not nice to be on the wrong end of. Click this link to watch an inspiring 3-minute video by the legend Sadhguru on the problem with the word “best”, and how to avoid unhealthy comparisons.

As for keeping others in darkness? Mystery is great but it's darkness not blindness; if you are too hidden, you will feel isolated, lost, be without help when you need it and losing opportunities. If you share too much, you will face compromised freedom, unwanted attention and be an easier target for negative judgement. Be selective what you share, who you share it with and find the right balance!

2.4: Contents of the cosmos

Natural sciences is a fascinating subject overall, my main interest within it is astronomy and the night sky. It all shows us how amazing the universe really is.



The biology of how we're all made, the functions of cells and organs, our ability to have thoughts and concepts, the arrangement of atoms, the structure of molecules, the unique properties of water, how electric charges work, the geology of rocks and planets, the geometry of snowflakes, the electromagnetic spectrum, how gravity and other forces work, how particles interact with the magnetic field, the complexity of this planet's 5 layers of atmosphere, how Earth interacts with the sun and moon, the auroras resulting from solar activity, stellar properties, the sheer size of the universe, how the supernovae (death of very massive stars) gave birth to all the elements we cannot survive without and I'm sure we can think of more. Just look around you, it's everywhere.

Did any higher powers design it all, or did it all happen by itself? Science can influence beliefs either way, but the sad truth is: we can only believe in one or the other, no one knows for sure. All we can conclude is that the universe is an amazing creation, and we can seek to understand rather than know, which is what the next section is about.

2.5: Dark faith is not blind faith

A key theme here is understanding any higher powers through their magnificence as reflected by the cosmos. Does common fear-based dogma really align with this understanding?



A lot of strict religious dogma demands complete unquestioning submission to an authority that controls by instilling fear, guilt and ignorance. No questioning is no understanding, which is why acts of blind obedience often fail to live up to their own alleged purpose, or even backfire with opposite effects. An authority that censors or prohibits even exploring alternative ideas is insecure, fragile and ironically unfaithful.

There is satire in Darkwards Code #5: Know the night sky, where “not tracking the lunar phase" is frivolously listed as a horrendous sin you'll burn in hell-fire for. It's how fear and lies are used to control, and to believe such ideas is an insulting way to imagine the higher powers; is God a magnificent creator of galaxies, or an insecure tyrannical despot with an astronomical ego? The legend and Islamic super-scholar Mufti Abu Layth has some words of reassurance. However, I believe the actual heaven and hell are more likely here on Earth.

By going out and observing how amazing this universe is, I felt that any higher powers would surely be better than rigid rules, fear and punishment, and their magnificence shows how no religion can stand as an excuse for injustice. The universe gave me a faith exclusively in magnificence of the creation. Faith does not have to come with oppressive dogma or any religious identity, so choose any faith you wish, look to the stars and see that to follow sense and ask questions is not unfaithful! Like the stars appear in darkness not blindness, dark faith is not blind faith. My name is Darkwards666, not Blindwards666.

2.6: A follower's story

The following is a message sent to me by a follower of darkness who was interested in contributing to this site, who shared his story of how he found his connection with the universe and higher powers:

I was in the forest at dawn, when the mist was painting each leaf and branch with a quiet light. I could almost trace a pattern in the way the sun wove through the trees ,a delicate lacework of shadows and gold. In that moment, everything felt intentional, as if the universe itself was an old icon, patiently revealing its mystery to me. It’s not a doctrine or lesson I learned in church that made me feel this way; it’s a whisper in my heart when I see the spiral of a seashell or the geometry of a snowflake. I find myself smiling as I wonder if the stars above me are scribbling secret verses only my soul can read. There’s a stillness, a subtle pulse, that reminds me of Christ’s presence in the small things. And though I’m not making bold statements, my faith quietly kneels before these wonders :each one a gentle invitation, drawing me closer to the One who planted these patterns in creation.
09:49

Any story that begins in a forest at dawn is bound to be good, this one is definitely no exception! It's great to see such a connection formed by sensing the wonders of the forest, and so much appreciation of the simple things. I can also relate to how the wonders around us can feel so intentionally designed. I can see this is a very sincere faith, a forest is certainly one of the most powerful ways to start. The real question is though, why was he out in the forest so late? Or was it early?

Dark 3: Levels of Darkness

3.1: Overview of twilight

Twilight is the transitional stage in between day and night, after sunset or before sunrise. The definition from timeanddate.com: "Twilight occurs when Earth's upper atmosphere scatters and refracts sunlight which illuminates the lower atmosphere." To be truly darkwards, it is important to know the stages of darkness/twilight.

Image provided by timeanddate.com

3.2: Civil twilight

At civil twilight, the sun is between 0° - 6° below the horizon.



Civil dusk is just after sunset, and civil dawn is just before sunrise. This is the brightest stage of sundown, there is enough light to allow for most normal daily activities like sports and gardening to continue without difficulty. In any location less than 6° outside the Arctic or Antarctic circle, darkness does not exceed civil twilight during the summer solstice.

3.3: Nautical twilight

At nautical twilight, the sun is between 6° - 12° below the horizon.



This is the intermediate stage of twilight, where the sky is relatively dark, many celestial objects are visible but there is enough light for sailors to distinguish the sea from the horizon. This is where the name "nautical twilight" comes from. In any location less than 12° outside the Arctic or Antarctic circle, darkness does not exceed nautical twilight during the summer solstice.

3.4: Astronomical twilight

At astronomical twilight, the sun is between 12° - 18° below the horizon.



This is the darkest stage of twilight, and most people could not distinguish it from night. In light-polluted areas or on cloudy nights this is as dark as it gets, although in darker areas there is still enough light scattered from the upper atmosphere to make faint celestial objects less visible to astronomers, which is where the name "astronomical twilight" comes from. Despite the strict definitions in terms of the sun's position, from my experience I can detect a faint glimmer of light in the sky whenever the sun is 13° below the horizon or less. In any location less than 18° outside the Arctic or Antarctic circle, darkness does not exceed astronomical twilight during the summer solstice.

3.5: Night and other planets

At night, the sun is at least 18° below the horizon.



The night is Darkwards' favourite stage! At this stage, the sun is 18° below the horizon, which is defined as the point where no sunlight scattered by the upper atmosphere can reach us; the sky is fully dark and true night begins. For night sky lovers, this is the best stage and when the most celestial objects are visible.

On planet Mercury, the night virtually starts as soon as the sun sets, there is no transitional twilight stage because there is no atmosphere to scatter any light. On planet Mars, the atmosphere is also very thin but twilight is actually very long because light is primarily scattered by the many high-altitude dust particles in the Martian atmosphere. The atmosphere and light scattering of both Earth and Mars give the sky interesting colours, and even more so if volcanic material enters the atmosphere.

Dark 4: Night Sky (Moon)

4.1: Lunar cycle and phases

The night sky is an important part of the nature at night, this specific focus of Section 4 is on observing the moon. The moon orbits around the Earth’s common centre of gravity, cycling between 8 different lunar phases in a cycle of about 29.5 days. The time between one new moon and the next is known as a lunar month. The moon’s appearance in the sky varies from 0% illuminated and invisible during the new moon, to 100% illuminated during the full moon and everything in between. All 8 lunar phases are shown in this image, taken from the website timeanddate.com.

Waxing means to be increasing in size, and waning means to be decreasing. A crescent moon is banana-shaped and mostly unilluminated, while a gibbous moon is more than half illuminated but not quite full. A quarter moon, despite the name, is a half-illuminated moon. Refer back to this section if you ever forget any of the lunar phases.

4.2: How a full moon appears

A full moon is arguably the most spectacular phase of the 29.5 day cycle, and it appears when the side of the moon which faces us is fully illuminated by the sun. For this to occur, the moon must be on the opposite side to our planet as the sun, as illustrated in the following drawing:

Notice that the daytime and night-time side of Earth and of each moon are also shown in the image, and in every case, the daytime side is the side which is facing the sun, and the night-time side is facing away from the sun. A full moon is always opposite the sun, and never visible during daylight.

You may be wondering why our planet doesn’t block the sunlight that reaches the full moon; the answer is that it sometimes does, either partially or fully, and when this happens, we get an eclipse. The reason eclipses don’t happen very often is because the moon’s orbital plane around us is tilted by 5°, just like ours around the sun is tilted by 23°. If the moon and sun could somehow appear together in the sky, the moon would appear between 5° north to 5° south of the sun due to its tilt. If the moon wasn’t tilted, there would be eclipses at every new moon and every full moon.

4.3: Dark side of the moon

You may know that one side of the moon is always facing Earth, and the other side always facing away - the latter is often called "the dark side of the moon". The scientific reason for the same side always facing us is that the moon is tidally locked to Earth, a result of gravitational forces. However, is "the dark side" really the technically correct name?

The side which never faces us does not get any less sunlight than the side which always faces us, and this can be illustrated with the same drawing from Section 4.2. Notice how at the new moon, the side which faces away from us is entirely lit by the sun, and during the quarter moons half of each side is sunlit. Therefore, the more technically correct term is the far side of the moon.

4.4: Supermoons and micromoons

You may have noticed that some full moons appear bigger than others, especially when they are first rising and appear orange/red. The reason they appear this colour when they are just rising or setting is because of the indirect angle at which they face us. During moonrise or moonset, the moon is very low on the horizon and its light has to travel through much more atmosphere to reach our eyes; the blue light wavelengths are shorter and are scattered by the atmosphere, and only the longer red/orange wavelengths can travel through so much atmosphere and reach our eyes. This is the same reason why the sky appears red during sunrise or sunset. The moon also appears larger during moonrise, and it is believed this is because when it is low there are nearby objects like houses and trees to compare it with, which cannot happen when the moon is high.

However, what's described above is simply a result of the atmosphere and optical illusions, and is not what defines a supermoon! Supermoons are defined by moon distance to Earth. The moon’s orbit around the Earth is quite elliptical; its average distance from Earth is 384,000km, but it can be 21,000km closer or further away than that. Two important terms are: perigee (closest distance) and apogee (furthest distance). The less the distance, the larger the moon appears in the sky. When a full moon occurs during perigee we see a supermoon, which is the moon at its biggest and brightest. When it occurs during apogee, we get the opposite; a micromoon, which is the full moon at its smallest. A supermoon appears roughly 14% bigger and 30% brighter than a micro-moon

4.5: Full moon altitude

You may notice from my full moon blog that in the winter photos I pointed high up to the sky, but in summer months the camera is angled much lower. In winter, the full moon is high and brings lots of light into the dark forest, but in summer it doesn’t. This section explores why that happens.

When the Earth’s northern hemisphere is tilted towards the sun in June, we have summer; the sun is up for longer and appears much higher in the sky. We learnt in Section 4.2 that the full moon is opposite the sun, and now we learn that that also applies to its altitude. If the northern hemisphere is tilted towards the sun in summer, then it will be tilted in the opposite direction, which is away from, to the full moon. Notice how, in the following drawing:

In December, the northern winter, the exact opposite happens, and here is a drawing to illustrate it:

Notice that in the winter illustration, the northern hemisphere faces the full moon much more directly than the new moon or sun, as illustrated by the white lines. This is why I have to point to the sky much more in winter than in summer when I take full moon photos, and the moonlight effect is stronger in winter.

What happens during the equinoxes, when neither hemisphere is tilted towards the sun any more than the other? In this case, the opposite of 0 is 0, and the full moon appears at a medium height, which the following drawing illustrates. The equinoxes are an interesting subject when observing the altitude of quarter moons, which is what the next section, 4.6, is about.

4.6: Quarter moon altitude

A quarter moon is a half-lit moon, halfway between the new and full moon. If you do not know the lunar phases at this point, please go back to Section 4.1 as this section assumes knowledge from earlier sections.

What is the height of quarter moons during the summer or winter solstice? Let's analyze this drawing:

While it may appear as though the first quarter moon is closer to the northern hemisphere, this is just a natural error of a 2D drawing. A white line has been drawn straight from the first quarter to the last quarter, and at its center does not point towards either hemisphere. For this reason, both quarter moons, during both the summer and winter solstice, appear at a medium height. Next, let's look at the equinoxes.

This image was drawn for the March equinox, spring in the northern hemisphere, again with lines drawn straight down or up from both the quarter moons. Which hemisphere does their center align with?

Notice that in this image, when you draw a straight line down from the first quarter moon, it is clearly in line with the northern hemisphere. This is why, in the March equinox, the first quarter moon is at highest and the last quarter moon is at its lowest. What happens during the opposite equinox that occurs in September?

It is important to note that the moon orbits the Earth in an anti-clockwise direction, which is illustrated in all the drawings. For this reason, when the Earth is on the opposite side of the sun at the opposite equinox, the two quarter moons' altitude is also reversed. In September, the last quarter moon is clearly aligned with the northern hemisphere, it becomes the moon phase that appears highest, and first quarter becomes the lowest.

So far we have explored four moon phases a lot: the new moon, full moon and two quarter moons... what about the other four? When does a waxing gibbous appear at its highest? This needs no image illustration, but can be worked out by knowing that a waxing gibbous is the phase in between first quarter and full moon. The first quarter moon appears highest in March, and the full moon appears highest in December... so the waxing gibbous will appear highest in January-February. When the waxing gibbous appears at its highest, the waning crescent would be at its lowest. Finally, let's create a table to summarize:

Moon phase altitude
Moon phase Peak northern altitude Peak southern altitude
New moon June December
Waxing crescent April-May October-November
First quarter March September
Waxing gibbous January-February July-August
Full moon December June
Waning gibbous October-November April-May
Last quarter September March
Waning crescent July-August January-February
4.7: Waxing or waning

We know by now that a waxing moon is increasing in size, and a waning moon is decreasing... but how do you tell them apart visually?

To understand how, when and where they appear, we must understand the affect of Earth's rotation on its axis. Due to this rotation, all the stars, the sun and the moon all rise in the east and set in the west. However, when the Earth has completed one rotation on its axis, Earth has also moved around by the sun by 1°, and the moon has moved around Earth by about 13°. This requires the Earth to rotate an extra 1° to face the sun in the same position again, and 13° for the moon, with this difference of 12° taking about 50 minutes. This is why, one full motion in the sky takes the moon 50 minutes longer than the sun, and the moon would appear to move slower. This difference is also covered and illustrated with further imagery in the section about stars, Section 5.5.

At the start of a new lunar month, when the new moon and sun are on the same line, the moon's slower motion in the sky causes it to continuously move further east of the sun, rising and setting later every day. This affects its appearance - a waxing crescent moon is just behind the sun and is illuminated on the west side. If you are in the northern hemisphere above the tropics, the moon always appears due south: if you face south, west is on your right, therefore in the northern hemisphere a waxing moon is always illuminated on the right, and a waning moon is illuminated on the left. In the southern hemisphere, where the moon appears due north, it's reversed - waxing is left and waning is right. This is how, just by looking to the sky, you can easily tell whether the moon is waxing or waning.

Another easy way to tell the difference is that a waxing moon being behind the sun, will appear at sunset and set at night, while the waning moon rises at night and is visible until dawn.

Dark 5: Night Sky (Stars)

5.1: Observing night in nature

The night sky is an important part of the nature at night, this specific focus of Section 5 is on observing the stars. It's very unfortunate how light pollution ruins the night sky. The best time of the month to see the most stars is at or close to the new moon phase, because the sky is darker with no moon. The full moon is spectacular but is a natural source of light, so keep track of the lunar phase and don't book stargazing trips when there's a big bright full moon! This site, Sky Map Online, shows what stars are visible in your location in the night sky right now.

5.2: Polaris - north star and compass

The north pole of our Earth is currently pointed towards the bright north star Polaris. In this image, drawn by me, the Earth is rotating on its axis, one star is in line with Earth’s equator, and the other (Polaris) is in line with the north pole.

As the Earth rotates on its own axis, it can be directly facing or opposite the star shown at the equator, but the north star is at the axis of rotation so the northern hemisphere is always facing Polaris.

Anyone in the northern hemisphere can see Polaris, and it does not change its position in the sky. If you can locate the star in Ursa Minor, it will show you which way north is, then east on your left, west on your right, and south behind. If you have not located Polaris before, you can use the method shown in this image.

There is no equally visible south star, I believe that in the southern hemisphere they have their own navigation method of finding south by lining up constellations, but I do not know it, because I have not been there. Maybe you have the answer?

5.3: Star co-ordinates: declination

All stars have celestial co-ordinates so that they can be located in the sky. The first co-ordinate is called declination, ranging from +90 at the north pole to -90 at the south pole. If you observe the sky and look straight at the zenith, which is the point in the sky directly overhead, any star you see there will have the same latitude as the point on Earth at which you are observing from. For an observer standing at 60°N, this is a star with a declination of +60.

To an observer standing at any point on Earth at latitude 60°N, a star like Polaris with a declination of +90 will appear 30° north of the zenith. To the same observer standing at 60°N, a star with a declination of 0 (the celestial equator) will at peak altitude appear 60° south of the zenith. Any star with a declination further south than -30 will not be visible to the observer at 60°N on Earth. Here is an image drawn by me, not to scale, and with a table to summarize.


Star Visibility from Earth at 60°N Latitude
Star declination Visibility at 60°N Altitude above horizon
+90 30° north of zenith 60° above horizon
+60 At the zenith 90° above horizon (directly overhead)
0 60° south of zenith 30° above horizon
-40 Not visible at all Below horizon

Keep in mind this table is only for stars as they cross the meridian (more on that in Section 5.6). Any star with a declination 90° or further from the latitude at which you stand on Earth is not visible, this is why Polaris is always invisible for the entire southern hemisphere.

What is the declination of the sun? That depends on the time of year: during the equinoxes, it is 0, but in June it is +23 and in December it is -23. This is because Earth’s orbital plane is tilted by 23°, and is why we have the seasons: when the northern hemisphere tilts towards the sun in June, it is their summer.

5.4: Circumpolar stars

A circumpolar star is a star that is always visible and never sets: the most notable example being the north star Polaris for the entire northern hemisphere. One can say that the stars rise in the east and set in the west just like the sun, but it may be even more accurate to say that they all appear to revolve in an anti-clockwise motion around the specific point where Polaris sits, completing one full circuit in the length of a sidereal day which is 23h 56m 4s. Here is an image drawn by me to illustrate how stars, due to Earth’s rotation, appear to revolve around Polaris:

We can see that the closer a star is to a polar declination, the more likely it is to be circumpolar. If you stand at a location on Earth that is 60°N in latitude, any star up to 60° south of Polaris is always visible - stars that have a declination between +30 and +90. If you stand at a location that is 20°N in latitude, any star up to 20° south of Polaris or with declination between +70 and +90 is always visible. There are far more circumpolar stars the closer you go to the north or south pole of the Earth.

5.5: Sidereal night ≠ solar night

The correct term is day not night, but I am Darkwards and I obviously like the word night more. Due to Earth's rotation, all stars rise in the east and set in the west, taking 23h 56m 4s to complete one full motion, the same time taken for Earth to spin once on its axis. This is known as a sidereal day. Why does one day on Earth relative to the sun take slightly longer at 24 hours? The answer is: every time Earth completes one rotation on its axis, it has moved by 1° in its orbit around the sun, so it must rotate an extra 1° for one sunrise to the next compared to the other stars. This is known as a solar day. The extra 1° of rotation takes 3.9 minutes, which causes the sun to fall 3.9 minutes further behind (east of) the stars in the sky every night. This is the difference between a sidereal day (a day relative to stars) and solar day (a day relative to the sun).

Here is an image, not drawn to scale, to illustrate why a solar day on Earth is 4 minutes longer than a sidereal day, and why Earth has to rotate more than 360° for the sun to go from one point in the sky to the same point next day.

What happens on other planets, especially those closest to the sun? The length difference between their sidereal and solar days can end up being much more significant than on Earth as it requires a lot more than just 1° of extra rotation. This is explored in depth and darkness in the planets section. The difference between a sidereal day and solar day will continue to be relevant in multiple later sections.

5.6: Star co-ordinates: right ascension

Every star has celestial co-ordinates that include a declination which we looked at in Section 5.3, and right ascension, which is the focus of this section. The definition of a star’s right ascension: how many hours the star appears behind the sun in the sky on the day of the northern vernal equinox (generally March 20th). This figure ranges between 0h and 23h 59m. Here is an image to demonstrate the Earth going around the sun as it faces stars with different right ascensions, not to scale, drawn by me:

We can see from this image that in March, stars with a RA of 0h are on the same side of the sun, and stars with a RA of 12h are on the opposite side, which makes the stars with a RA of 12h most visible in the March night sky, and 0h the least visible. Here are a few examples of bright and well known seasonal stars:

Remember that due to the difference between a sidereal and solar day, as explained in Section 5.5, the stars catch up with the sun by 3.9 minutes every day, which is 2 hours per month; if a star has a RA of 6h, it will be 4h behind the sun one month later in April, then 0h behind the sun three months later in June.

Stars' best viewing time by RA:
Time of day March June September December
Midday: least visible 0h 6h 12h 18h
6pm 6h 12h 18h 0h
Midnight: most visible 12h 18h 0h 6h
6am 18h 0h 6h 12h

Keep in mind that the midday this table refers to may be slightly out of sync with the time when your watch says midday, as right ascension is based on the time that solar noon occurred in your location on the day of the March equinox. If clocks later go forward by an hour, this also needs to be taken into account. Solar noon is the halfway point between sunrise and sunset, the point when the sun is at its highest and crosses the meridian. This is why I am always in arguments about whether it's the morning or afternoon!

This is a good list of the 200 brightest stars in the sky with their celestial co-ordinates included. You could use this information to go outside and locate some stars! The lower the number is for a star’s apparent magnitude, the brighter it appears in the night sky.

5.7: Night sky used to tell the time

If you know the RA of any stars (RA explained in Section 5.6), you can use a method I discovered for myself and have successfully used before to estimate the time. We know that every night the sun falls behind the stars by 3.9 minutes, due to the difference between a sidereal day and solar day; this 3.9 minutes adds up to approximately 2 hours every month.

To calculate the time at which stars cross the meridian: add the sun's number of hours behind a RA 0h star for the current time of year (+2 for every month after the March equinox), plus the number of hours after the time of solar midday on the March equinox.


10pm on July 21st
Date Sun's hrs behind 0h stars Hours after midday Stars crossing the meridian
July 21st 8h 10h 8h + 10h = RA 18h

If you see RA 18h stars culminating (crossing the meridian) on July 21st, the time will be 10 hours after the time of solar midday of the March equinox... roughly 10pm. Vega is a famous star and 5th brightest in the sky with a right ascension of 18h! At around 10pm on July 21st Vega reaches its highest point, crossing the meridian lining up with the north star Polaris. If Vega appears in the east, the time is earlier, and if it's west the time is later.

Let's try another example!

4am on October 6th
Date Sun's hrs behind 0h stars Hours after midday Stars crossing the meridian
October 6th 13h 16h 13h + 16h = RA 29h (?)

Oops, there’s a problem here, no star has a right ascension of 29h... easy fix: the hours reset after 24h, so we can find the solution: 29h – 24h = 5h

At 4am on October 6th: the stars with RA 5h at their highest. A lot of stars in the constellation Orion have RA of roughly 5h. Whenever I see Orion already halfway through its journey in the sky from east to west in early October, it silently screams that I have stayed up way too late.

5.8: Star signs and zodiacs

The star sign we commonly associate with is the zodiac constellation that was on Earth's same side as the sun 2,000 years ago on the same date we were born. At the time star signs were invented, an additional Earth motion called axial precession was not known about, which is the direction of the Earth’s tilt changing in a 3D motion like a spinning top, in the opposite direction to Earth's orbit on its axis and around the sun, with one full circuit of this motion taking 26,000 years. Here is an image taken from Wikipedia to illustrate it:

Most people born in late March will believe their star sign is Aries, but this is only based on Aries being in line with the sun on the same side in late March 2,000 years ago. What happens 13,000 years later, when the tilt is facing the opposite direction? The following images, not to scale, both drawn for the March equinox, illustrate:

Why is Earth on the opposite side to the sun in the image after 13,000 years? Because, as the tilt direction changed to the opposite direction, it was necessary to preserve the date of the vernal equinox as March 20th. To illustrate: June may be northern summer today as it's when the north tilts towards the sun... but what happens 13,000 years later when the tilt is facing the other way? June would then become the month of northern winter solstice! They design the Gregorian calendar to ensure this doesn't happen, but the effect is that star signs become out of sync with modern astronomy.

We can see that in the first picture, Earth was lined up with the sun and Aries, albeit not drawn well to scale... but 13,000 years later ends up with the sun and Aries on the opposite sides and totally out of sync. Today’s star signs are already one month out of sync and counting; those born in late March are known as Aries but by modern astronomy are actually Pisces. I believe the horoscopes' failure to observe this misalignment is enough to raise serious questions on whether their words have truth. They are also not backed up by any scientific evidence.

Dark 6: Night Sky (Planets)

6.1: Inner planets

The planets appear like stars in the night sky, but they are generally brighter and don’t twinkle as much. Unlike the stars, planets do not emit their own light, what we see is sunlight reflected off their surface. Mercury and Venus are the two planets closest to the sun, both reaching scorching temperatures of well over 400°C, although Mercury is extremely cold at night. As both planets are closer to the sun than Earth, we can never see them at midnight when we are facing away from the sun. The following drawing shows why:

As they are closer to the sun than Earth, they can only be seen in the night sky around either sunrise or sunset. Venus is the brightest object in the night sky, only the moon and the sun are brighter.

6.2: Outer planets

Mars, Jupiter and Saturn are the three most visible outer planets, and while they vary considerably in brightness according to their position, Jupiter is almost always the brightest due to its size and reflectivity. The two outermost and coldest planets, Uranus and Neptune, are generally too dim and far to be visible with the naked eye. The following image is not close to drawn to scale.

The outer planets appear at their best and brightest in the night sky when Earth is between them and the sun, facing away from the sun and towards the outer planet, just like the full moon. All planets have elliptical orbits around the sun, and they appear at their absolute brightest if they are in alignment while also at perigee (closest to the sun) and Earth is at apogee (furthest from the sun), but these are exceptional events.

One of my most memorable night sky events is from the night of July 6 2020, where the full moon, Jupiter and Saturn formed a triangle in the sky. It was before I started taking decent photos, but I remember I stayed outside until dawn that night.

6.3: Days longer than years?

It is commonly believed that a day on Venus is longer than a year, but does it also consider the time between one sunrise and the next on Venus?

In terms of sidereal motion, Venus takes 243 Earth days to spin once on its own axis, and 224 Earth days to make one trip around the sun. It is explained in Section 5.5 why a solar day on Earth is slightly longer than a sidereal day... but another important point is that Earth’s axial rotation and orbit both follow the same direction. On Venus, this is not the case! Venus is the only planet in the solar system that rotates on its axis in the opposite direction to its orbit, so unlike other planets it has to rotate less than 360° for the sun to complete one full motion in the sky from one sunrise to the next, shortening the solar day to just 117 Earth days. By this definition, if you could observe a solar day by standing on Venus without dying, it would not even be close to longer than a year.

Is Mercury in fact the real winner for long days? Mercury takes 59 Earth days to rotate once on its axis, and just 88 Earth days to make one trip around the sun. When Mercury has finished one rotation on its own axis, it's about 66.6% of the way through its orbit – so much that Mercury has to spin on its axis exactly three times for the sun to complete a full motion in its sky. A day as observed on the surface of Mercury is not just longer than a year, but it would take a Mercurian year just to go from sunrise to sunset, or the other way round. One solar day on Mercury takes the same length as two Mercurian years, and three sidereal days.
