Look at this shit. Do you know what this is? It's a sunrise on Mars. Fucking Mars.
>Whoa cool...moving on
No, stop. Think about that for a minute. Do you realize how amazing this picture is. I mean, think about it. It's a picture of a sunrise as seen from ANOTHER PLANET. This isn't some lame ass "artist's concept" of what a sunrise would look like on Mars. This isn't some picture a hippie took with his digital camera while hiking through the desert one morning. This is an actual picture that was actually taken on Mars. What you're looking at in this picture is what you would actually see if you went to Mars, landed on the surface, and watched the sunrise.

I mean, do you realize how crazy it is that we even managed to do this in the first place?

And speaking of shit we shouldn't even have been able to do, here's a picture of an Earthrise from the moon. Think about that. This picture is the complete opposite of what you see (almost) every night. Instead of being on Earth seeing the moonrise, you're on the fucking moon watching EARTHrise. And look, it's a half-Earth. If you were on the moon, this would just be another phase of the Earth for you, much like how we have phases of the moon here on Earth. You'd have your quarter-earth, full earth, etc.
And remember, this shot was taken by actual people, not a robot. Again, you realize just how insane that is? Nevermind sending robots to other planets, nevermind putting people in orbit. WE LANDED PEOPLE ON ANOTHER CELESTIAL BODY. We are the only known living organism in the universe to have actually LEFT it's home planet to go and walk around on another celestial body. Not even 100 years ago people could only look up at the moon and go "that's pretty" never thinking that it would ever be more to people than just some bright object in the night sky. But then just a couple decades later we're walking on it.

Finally, here's Jupiter. I don't know what it is about these pictures, but photos of Jupiter and Saturn creep me the fuck out. The photos look banal enough. If you looked at them alongside pictures of Mercury and Venus and didn't know anything about the planets you'd assume they were all roughly the same size. But no, Jupiter is fucking huge. Just to get the whole planet in this picture the probe that took it had to be 25 million miles away. Do you realize how far away that is? That's roughly 2/3 the distance between Earth and Mars. Notice how tiny the Sun is in the OP pic compared to how it looks on Earth? That's how much smaller the freaking Sun gets when you move 35 million more miles away. Now take that idea of distance and realize that this picture was taken from 2/3 of that distance away from Jupiter and yet it looks like you're the same distance from it as you would be if you took a picture of Earth from Orbit. That's how huge Jupiter is.

And that's what creeps me the fuck out about it. It's like staring into the ocean on a pitch black night when you're floating over the mariana trench. You just realize how utterly insignificant you are, how incomprehensiably tiny. You could be swallowed up by the thing and crushed out of existence and absolutely nothing observable would happen.

Then when it landed, it's camera took some pictures, and the drunk janitors at NASA took turns fucking around with the controls until it got stuck.

Would this "Earthrise" emit a dim light over the dark side of the Moon, similar to the the moonlight that we receive here on Earth? Would it simply be not quite as bright?

Also, would we be able to see more of the Milky Way galaxy on the night side of the Moon than what we see here on Earth during the night?

Dark side of the moon is "dark" because it never faces Earth. So no, it would never be illuminated by Earth for the same reason that there's no moonlight when there's no moon in the sky.

And yeah, you'd have an easier time seeing the milky way since there wouldn't be any lights or even an atmosphere to get in your way.

>Dark side of the moon is "dark" because it never faces Earth. So no, it would never be illuminated by Earth for the same reason that there's no moonlight when there's no moon in the sky.
I am aware of this. However, it is my understanding that the part of the Moon that faces the Earth will sometimes not be exposed to direct sunlight during certain times of a month. During this time, would it be possible for the Earth to illuminate the darkened area on the Moon similar to how the Moon illuminates the part of the Earth that is not directly facing the Sun?
>And yeah, you'd have an easier time seeing the milky way since there wouldn't be any lights or even an atmosphere to get in your way.
I was under the impression that you could not see the Milky Way on the Moon when the Sun is out. Apparently, the astronauts could not see the stars during the time that they were there. Or am I incorrect?

What you are seeing is a long-term exposure of the milky way as seen from Australia. An actual look using the eye's short-exposure (hurdur) time would, amazingly, not look very dim. It's actually possible to see amazing shit without having Hubble's pictures superimposed with infrared, gamma rays, x-rays, and every other wavelenght of radiation, along with long-exposure... You get the idea.

Anyways, the view shows a line of stars perpendicular to the equator. Most know it as the Milky Way.

Well, that is the equator of the galaxy, as seen from our tiny spot, 25,000 light years away from the Central Galactic Black Hole. So we are surrounded in all directions (Not so much to the Galactic North and South, but still) by other star systems, and Hydrogen-Helium nebulae that will eventually give birth to other stars.

Our sun is merely a large-scale fusion reactor, constantly blowing out radiation into space, and trillions upon trillions of tonnes of Hydrogen are constantly flying away from it only to spiral back inwards at the Heliopause, where the Solar Wind meets the Galactic Wind. In a way, the Sun's magnetic field acts as a magnetic parachute, pushing our star in its orbit around the Central Black Hole, for another circuit, another quarter of a million years of spinning around. And in that short time, it doesn't look like we're moving because the stars are moving along with us.

And there it is: The galactic equator. Every star that is within reach of humanity thanks to the benefits of relativistic time dilation.

Every star, nebula, planetary disk, every gas giant, every forgotten, failed brown dwarf star, every asteroid and every comet, every moon, every planet.

All the sentients and the non-sentients, the single-celled organisms trapped in cryvolcanic vents in some distant comet as it flies by its parent star, to beings capable of designing, putting together, and flying antimatter-driven rockets to near the speed of light and back to stationary.

Yeah, you're right. I confused myself. I forgot that when you can see the moon it's behind the Earth since it's reflecting sunlight towards the Earth, and when you can't see it it's actually in front of the Earth where would only be visible during the day were it not for the fact that it isn't reflecting any sunlight towards Earth. So yeah, you'd get some Earthlight reflected on the moon as well.

>I was under the impression that you could not see the Milky Way on the Moon when the Sun is out. Apparently, the astronauts could not see the stars during the time that they were there. Or am I incorrect?

Why do people always say this? I NEVER feel insignificant thinking about the cosmos. For eons, stars and nebulae and planets and supernova go about doing their methodical slow mathematically-governed business, and then suddenly we arise on one watery little rock, look up at the heavens and say "Time to get shit done." Space is incredibly vast, yet we have the capacity to calculate that vastness and discover the mysteries that surround us in countless galaxies. We move between worlds at will, we have the power, if not the resources yet, to alter the trajectory of asteroids, to change the surface of a planet, to send out signals and radiation and energy through space that previously could only be done by the unthinking reactions of solar furnaces. What before was never-changing is now changeable by our desires. Perhaps we cannot fully yet truly comprehend all the laws that govern the universe, but we have our foot wedged firmly in the door of knowledge and we're only a couple crowbars away understanding. We are the cosmos formed into living, thinking, doing creatures, capable of leaving our mark wherever we will it in this garden we have arisen in.

From this distant vantage point, the Earth might not seem of particular interest. But for us, it's different. Consider again that dot. That's here, that's home, that's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.
The Earth is a very small stage in a vast cosmic arena. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.
The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.
It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.

Probably due to the different atmosphere on Mars compared to the Earth's.

I would give anything to stand on the Moon or Mars.

If I had one wish...

Just to stand there for even a split second. They said that the astronauts who landed on it immediately had a life changing experience that really put everything in perspective.

Light scattering on mars is due to suspended dust particles instead of air as its got a stupidly thin atmosphere. You get red skies and blue sunsets. We can see the same on earth if u got alot of crap in the air (heavy pollution, dust storms, etc)

We're all young. One day, my friends, we will all blast off from this planet toward our destinies, with our /sci/borgs by our sides, our knowledge in our heads, and Sagan in our hearts. We'll gaze out the digital view screen at what lies ahead, the incomprehensibly huge playground, the one our scientific forefathers dreamed about, and we'll shed a manly tear as we carry their memories throughout the galaxy.

To quote the writers of Star Trek, who are our brothers in spirit, I say,

To the journey.

Can you see phobos from the surface of Mars?

Maybe it would be very small, but cute instead!
