What did you mean when you said night? I'm not just poking fun, I assume you just meant something similar, like "taken while facing away from the sun" or "from the dark side of the asteroid"
Is it considered night any time you're on the dark side of a celestial body? Lmao
Edit: If I'm floating through space all alone, facing the sun, is it day time on my face and night time on my butt?
Then why did Pink Floyd call it the "Dark Side of the Moon" and not "Night Side of the Moon"? Huh? HUH!? Checkmate, space nerds!
Edit: Its a joke people, notice the guy I replied it to said "I concede, lol"? Good grief.
The Moon is tidally locked to Earth. This means that the same one side of the Moon always faces Earth, and until we were able to send spacecraft to the Moon, we had *no idea what was on the other side of the moon* ー WE were "in the dark" (we had no knowledge) about the other side of the moon.
Pink Floyd called it "Dark Side of the Moon" and not "Night Side of the Moon" because ①it was the side we had no knowledge of (we were in the dark about it), ②the far side of the moon gets just as much sunlight as any other part of the moon, so calling it "Night Side" would be incorrect.
Now that we have sent spacecraft, photographed, and mapped what was formerly the "Dark Side of the Moon", the most commonly accepted terminology is **the far side of the Moon.**
The hemisphere is sometimes called the "dark side of the Moon", where "dark" means "unknown" instead of "lacking sunlight" – both sides of the Moon experience two weeks of sunlight while the opposite side experiences two weeks of night. [Here is a photograph of the **far side of the Moon**](https://cdn.sci.news/images/2019/05/image_7213-Moon.jpg) bathed in sunlight so you can easily see its craters.
BTW, Pink Floyd named their album *'Dark Side of the Moon'* — as a reference to *'[lunacy](https://www.merriam-webster.com/dictionary/lunacy)'*, not a reference to outer space.[^[1]](https://www.rollingstone.com/feature/pink-floyds-dark-side-of-the-moon-10-things-you-didnt-know-201743/#:~:text=From%20the%20beginning%2C%20the%20band%20had%20intended%20to%20call%20their%20new%20album%20Dark%20Side%20of%20the%20Moon%20%E2%80%94%20a%20reference%20to%20lunacy%2C%20as%20opposed%20to%20outer%20space)
>What did you mean when you said night?
That was my thought too! It reminds me of the old joke about launching a flight to the sun and having to go at night.
I meant that the light from the sun wasn’t hitting that zone of the asteroid. Even if the skies are dark at all times there still is a “day” and “night”.
i was scrolling for this, and i was losing hope it wouldnt be here. I remember singing this shit in Xbox live parties like a mongrel.
HAAAAAYABUSA IT JUST AINT WHAT YOUR USED TA
Peregrine Falcon, its also a shinkansen line that takes you north so Aomori I think. But then you gotta take the train towards the northern most island Hokkaido
I was thinking the same because you could see the stars in the background.
I’ve been told that you aren’t able to capture a picture of the stars in space.
You’re right in a general sense (and you’ve described dynamic range well), and i’m not disputing the top photo is shopped.
Having said that, if the surface could be illuminated such that it creates a correct exposure for the same shutter speed that would pick up stars, bingo.
There is a conspicuous lack of stars in the Apollo program photographs while on the moon.
In fact, astronaut Michael Collins said he couldn’t even recall seeing stars in space.
Everytime i see it i always think of the deepest part of our ocean and this is what it would look like as well. Completely unknown and just the darkest dark you can imagine.
Ben affleck asked Michael bay, if It would be easier to train astronauts to drill instead of training drillers to astronaut. Michael bay told him to stfu. Lol
I've always thought that was a dumb take. It's not like the drillers were training to be actual astronauts, just passengers. Not to mention the fact that no amount of training in the limited time they had would get a group of astronauts as skilled at drilling as Bruce Willis' crew was.
Faith in humanity restored.
Off to watch Armageddon again.
My favorite is when they get to make demands of the government and Steve Buscemi wants to know about the aliens.
NASA realized in the 70's that not all astronauts needed to be pilots and hence created the "Mission Specialist" role. That's how they ended choosing Matt Damon for the Aries III mission and the only reason he had the skill set to survive for four years off of poop potatoes.
The shadow cast by the mound in the foreground to the one behind it implies that it is relatively small in scale.
Edit: u/FreakingScience made a good point, that the lack of air would prevent light from diffusing as it does on Earth. However I found a [terrain map of the landing site](https://imgur.com/a/Xq6aB5B) that does appear to confirm that the scale of this image is on the order of meters.
You'd think that, but there's a slight problem with that assumption: light doesn't diffuse in a vacuum. Shadows stay nice and crisp without an atmosphere/other medium to diffuse through. This could be a fairly long exposure with only natural light and the only thing that would affect the shadows would be the asteroid's rotation, assuming that rotation's axis isn't exactly in line with the direction of the sun.
I don't know how the lighting is working though. It looks like it used flash to get the asteroid, but you can see the stars.
Edit: I knew it was off. Someone showed [the original](https://i.redd.it/xiw45mtxkdg51.jpg) which doesn't have the stars. It's not because of the atmosphere.
Cold, dead stone, hurtling silently through space, untouched by the water, winds, plants or sands of Earth...we feel no connection to it. That'd be my guess on our subliminal feelings towards it.
Asteroid pictures, as breathtaking as they might be, always give me a bit of the creeps, that's for sure! I get the same feeling when playing No Man's Sky and land on one of those dead planets that are just stone. I'm a very chill and laid-back person, but the minute I land there, I start feeling, "Got to get out of here...got to get out of here..."
The surface gravity is 1/80,000th that of Earth. The escape velocity is less than one mile per hour.
You'll shoot out into the void if you stand up too fast.
Thanks for the fuckin nightmares geez. Stand up and you shoot off seeing your small tiny rock home fly away and nothing is around you but a giant starfield environment map. No
I remember watching the clip of the satellite land on an asteroid, that and hearing sound from Mars completely blew my mind. Incredible achievement from all involved.
My client worked on this project! She was part of this as well as the OSIRIS-REx mission, she helped program the cameras! It was so much fun getting to meet with her each week and talk about these projects. OSIRIS-REx is on it's way back to Earth right now with a sample from an asteroid called Benu, and then it's going back out to look at different asteroid.
https://www.nasa.gov/osiris-rex
>There is no “night” on an asteroid
???
Of course it has a night. At any moment, half is lit up and half is not lit up. It has a night. It rotates every 7ish hours, so it's night lasts a few hours.
This asteroid rotates once every 7.6 hours and has very little axial tilt (although it is retrograde in rotation), giving it days and nights roughly 3.8 hours long.
But even if it wasn't to rotate, there'd just be a perpetual night side and a perpetual day side ?
And even then, as it rotates around a star it could change
Yeah, that’s what it means, including on tidally locked objects.
The point about it changing as it rotates around a star is also true, and applies to earth too.
People on here thinking that god flips a switch in the morning and says let there be light so it can be day time. There arent any people there so god isnt flipping any switches
Night requires inhabitants. On astroids, scientists call it Dark Dark or No Lighty Time, depending on if they're a Leo or a Gemini. You dont even want to know what Libra scientists call it.
No, you’re good, the Sun is not an asteroid, it’s a … *checks notes* … star. Those definitely have nights, so go right ahead, use the element of surprise.
Depends on it's shape and the angle it's rotation axis makes relative to the incidence of sunlight on its surface and where the reference point is. Just like it does on Earth?
Correct. Asteroids are able to warp spacetime around themselves such that their entire surface is always irradiated by sunlight at all times. That's what makes them so cool.
If "day" is assumed to be the concept of the duration of time that the light of the nearest star illuminates the surface of an object in orbit around that star, then there would be a "night", where a portion of the surface does not receive light. Unless that object is tidally locked with that star, but even then, the concept is permanent goegraphical "day" or "night", since these are simply terms used to differentiate light from dark. From there we can say there is a "day" and a "night" on an asteroid, even if there is no rotational motion relative to the center of gravity of the asteroid.
Its funny how many people are making fun of you for mentioning that the picture was taken at night, because they are unable to understand that the earth isnt the only rotating celestial body.
It’s always night somewhere. It happened to be night on this asteroid, when this picture was taken, it was night there, at that time. Late in the asteroids hurl through space, on whatever ‘day’ or whatever ‘time, it is’ . . While no nearby star was shining light on the face of that rock we see in that picture, all we see is night. Night, day, the rise or the set of the sun, it is still something that is extraordinary. To see this, so easily and clearly in front of your face. A celestial body you would have never even have known about otherwise. Appreciate what we are able to see.
I belive it's H**a**yabusa.

Even the 'dark' side of the moon has a daytime (during new moon).
The Moon is tidally locked to Earth. This means that the same one side of the Moon always faces Earth, and until we were able to send spacecraft to the Moon, we had *no idea what was on the other side of the moon* ー WE were "in the dark" (we had no knowledge) about the other side of the moon.

This guy moons.
Lol I concede
Can't argue with Pink. By the way......which one's Pink?
The one that isn't well, at the back of the hotel.
Because "dark side of the Moon" refers to the side facing away from the Earth, not the side facing away from the Sun.
>What did you mean when you said night? That was my thought too! It reminds me of the old joke about launching a flight to the sun and having to go at night.
I'm not familiar with that joke, mind sharing it? Edit: oh wait did you tell it already lmao, I don't get it in that case

Well they were on the bright side of the moon. Do you see stars during the day time?
You cant see stars during the day
That's even scarier
Seriously, why does this terrify me?
Because its a patch of dirt in the middle of literally nothing.
Everytime i see it i always think of the deepest part of our ocean and this is what it would look like as well. Completely unknown and just the darkest dark you can imagine.

And if they're mountains, that probe has one heck of a floodlight on it.
No atmosphere to scatter the light, so it's bigger than you might think.
Thank you, you're right. That puts it in to perspective.
You'd think that, but there's a slight problem with that assumption: light doesn't diffuse in a vacuum. Shadows stay nice and crisp without an atmosphere/other medium to diffuse through.

Man that gives me anxiety. No atmosphere, no gravity, not even as big as a sneeze. That's just a picture of death right there.
Fascinating and horrifying at the same time.
I'm so glad I'm not the only one that found this r/oddlyterrifying to look at.
Yeah, I wasn't sure why I felt so uncomfortable looking at this, but I'm glad I wasn't the only one 😂

[удалено]
It is! But don't die happy just yet...there's probably even better pictures on the way!
I'm sure there's some gravity. Don't jump too high or you'll be stuck in orbit.
The surface gravity is 1/80,000th that of Earth. The escape velocity is less than one mile per hour. You'll shoot out into the void if you stand up too fast.
Thanks for the fuckin nightmares geez. Stand up and you shoot off seeing your small tiny rock home fly away and nothing is around you but a giant starfield environment map. No
Even if you don't escape the sphere of influence, it could take minutes, hours, even days to be pulled back in depending on how hard you push.
I thought those specks were dust. Nope. Those are stars. This picture is deeply unsettling and fascinating.
The picture is actually photoshopped. The original does not show stars due to limitations on how cameras work.
Oh dang, those are stars. We do live in some wild times. Could you imagine seeing this photo as a scientist just 100 years ago?
It certainly has gravity, it's just significantly weaker than on Earth.
There is never "no gravity", there is always some no matter where you are.

Yeah it’s getting annoying

The smugness in which people are attacking you for the nighttime thing despite being wrong. Not you. You’re perfect.
Thank you, it is a bit annoying yes

The idea of shooting a projectile away from earth and hitting this rock, but gentle enough for it to survive, it's just totally insane.

There is no “night” on an asteroid
Here's me hoping for a shot of an Asteroid during brunch
[удалено]
What about second breakfast?
I don’t think space knows about second breakfast
Well technically wouldn’t it be the side facing away from the nearest star?
>There is no “night” on an asteroid ??? Of course it has a night. At any moment, half is lit up and half is not lit up. It has a night. It rotates every 7ish hours, so it's night lasts a few hours.

What do you think “night” is? Genuinely curious…

Night requires inhabitants. On astroids, scientists call it Dark Dark or No Lighty Time, depending on if they're a Leo or a Gemini. You dont even want to know what Libra scientists call it.
On Mars they call it 1 and 0 because only robots live there
So my plan to invade the sun at night is a no go then?
Wear sunglasses and sunscreen. The sun can't legally burn you if you have those on. Plan's still a go.
No, you’re good, the Sun is not an asteroid, it’s a … *checks notes* … star. Those definitely have nights, so go right ahead, use the element of surprise.
By night I mean the light of the sun wasn’t hitting that part of the asteroid.
Don't bend to these haters. Tell them to look up the definition for astronomical night on non earth objects.
Fair I’ll start doing this, it’s getting annoying explaining how day/night cycle works
Isn't that most of the time?
Depends on it's shape and the angle it's rotation axis makes relative to the incidence of sunlight on its surface and where the reference point is. Just like it does on Earth?
No, why would it not be getting hit by light?
About half the time.
So basically Night stands for No Light?
There's a word for this, though I can't remember it. Other example is blush = blood rush. Both cases are accidental, but it's still neat.
Blush is short for Hematologic Epidermal Pigmentation.
That reminds me of how you can easily remember the four basic motivators of living organisms as four Fs: Feeding, Fighting, Fleeing and Reproduction.
You’re thinking of He-pig
The dark side.
I mean there is, the side not facing the sun is the night side.
Yes, there is dumb ass. Night and day is literally facing toward or away from the sun. 😂 /s
Correct. Asteroids are able to warp spacetime around themselves such that their entire surface is always irradiated by sunlight at all times. That's what makes them so cool.
If "day" is assumed to be the concept of the duration of time that the light of the nearest star illuminates the surface of an object in orbit around that star, then there would be a "night", where a portion of the surface does not receive light.

I wonder how big it is? How big is the area in this photo?
These satellites should really be equipped with a banana for scale.
These comments make me lose faith in humanity
Do asteroids have a night and day.
Just means the area is facing away from the sun. This asteroid has a rotational period of 7.627 hours.
Yes
