alanis: Clouds and shadows on Mars, photographed by Mars Express, 24th May 2012.

Between 28 and 36°S, 284°E, on the arc of highlands that surround the southeast Solis Planum. The crater split between the 2nd and 3rd images is Voeykov, about 75 km across, named for climatologist and geographer Alexander Ivanovich Voeykov (1842-1916). The small, deep crater toward bottom left of the 4th image is Los, named for a village of about 400 people in Gävleborg County, Sweden.

Composite of 3 visible light images for colour, and 5 monochrome images for animation. Colour is not balanced naturalistically, and the slightly psychedelic colours of the clouds are a result of mismatches between the images where the clouds have moved between exposures.

After the earth dies, some 5 billion years from now, after it’s burned to a crisp, or even swallowed by the Sun, there will be other worlds and stars and galaxies coming into being - and they will know nothing of a place once called Earth.

Photos: Comet 67P/Churyumov–Gerasimenko.

The European Space Agency’s Rosetta spacecraft successfully rendezvoused with Comet 67P/Churyumov–Gerasimenko this week, at a distance of 555 million kilometers from the Sun.

From the New York Times:

Over the coming months, Rosetta and its comet, called C-G for short, will plunge together toward the sun.

In November, a small 220-pound lander is to leave the spacecraft, set down on the comet and harpoon itself to the surface, the first time a spacecraft will gently land on a comet.
