The big one is probably an hot desert (because its surface is quite smooth), and the small one is an hot selena. (it has the classic "acne" of selenas) cool

An asteroid in a nebula, that orbits a...white main sequence star.

Ding Ding Ding! We have a winner! You guessed the blue planet right first.

Your turn.

Cool to see you guys kept this going in my absence. Since FastFourierTransform is 10 days late already, I figure I may follow with a picture of mine.

Who can tell me what's going on in this image?

Outside the milky way, a planet (or a moon) with atmosphere and aurora, two big moons visible (or a planet and a big moon) eclipsing together and with the first body. Another smaller moon. A planet with a moons system visible on the sky, and a few blue stars.

Awwww really?? am I late??
Ok I will try to reconquer my right to put an image. wink

We are flying above the shore of a lake located in a satellite with a thin atmosphere and magnetic field (because there's an aurora). We are above the galaxy in the halo (that's why we see the galaxy like that and that's why there are so many blue giants). The planet this moon orbits has many other moons. One of these moons can be seen during an eclipse over the planet. There's an other planet with moon in the upper-center part of the image. The diffuseness of the eclipse shadow indicates that the planet has a thick cloudy atmosphere that scatters the light.

Other observations (hypotetical, only for curiosity)
And it seems that there is another shadow over the planet, behind the moon mentioned earlier. Maybe is a double eclipse made by the same moon bacause there are two light sources (binary star system), but I don't think this is a good explanation since every light source would erase the other shadow (and i'ts improbable such small difference in color between the stars). I have another theory, the truth is that the "main shadow" it's generated by us, by the moon in witch we are located, and the other shadow is made by the other moon. Maybe I'm just imagining that second shadow over the surface of the planet.

Sorry for my english, one more time.

And the winner is... Voekoevaka.

He was pretty laconic, but spot on. And since he was first, he wins.

The geometry is as follows, although you wouldn't be able to deduce all this from the image alone. Indeed we're in the halo, on the surface of a Terra moon, near one of the poles. This moon is slightly heavier than the Earth and orbits a desert super-earth very Venus-like but much heavier. The moon we're on is the outermost of a system with two other moons, both much smaller. The larger of these two is eclipsing the primary and in turn being partially eclipsed by the moon we're on (BTW, the fuzzynness, FastFourierTransform, isn't due to the atmosphere. but because the system is pretty close to its star and the main eclipsing body is relatively distant), which is also eclipsing the primary. So we have a triple eclipse here. The other moon, the smaller of them all (and also the innermost, although you can't see that from the image) is shining brightly to the left. There's indeed another planet with a sprawling system of moons to the right. This one is a gas giant -- you wouldn't be able to be sure of this just by looking at this image, but the vastness of the moon system is a good hint of it.

This is one of the systems I created, and the blue stars are a bug in my star-generating algorithm -- I wanted a few but there should be far from that many. They aren't very common in the halo, BTW -- blue stars are creatures of dusty, star-forming areas, not of the vast and relatively empty expanses of the halo. The halo has little dust, and blue stars formed in the galactic arms just don't live long enough to reach it. That's something to change in the future, but you'll see them in many of my images.

So there. Go ahead, Voekoevaka, post something.

I remember I took an eerie screenshot a few weeks ago. It is time to share it :

It's a view from a few kilometers above the surface of a cold planet/moon (it's impossible to know on this screenshot), perhaps a desert or maybe a titan, with a rather thick atmosphere, orbiting a few hundred AU from a white, or maybe blue main sequence star that we can see in the sky. We can also barely see two planet orbiting closer to this star on the right (although they could just be very bright stars outside the system, but they are more likely to be planets because they seems to be aligned with the star).

Or maybe the planet is orbting an other star we can't see, which is orbiting around the main sequence star, and what we see is the night sky with the main sequence star.

Planets? or maybe lens flare artifacts?

relox84, this is not the right planet class, and the right star class. But it is simply the system's central star.
