This moon looks like a ball of cheese
|
view preview
The strangest moon in the Solar System is bright yellow. Taken by the Galileo spacecraft, this image shows Jupiter's moon, Io, and its incredibly bright colours derived from sulphur and molten silicate rock. Io is covered in volcanoes that are so active, they effectively turn the whole moon inside out. And some of Io's volcanic lava is so hot, it glows in the dark.

Pluto up-close
|
view preview
Taken from a range of just 17 000 km, these images were snapped during the spacecraft's closest approach to Pluto, from its flyby of the dwarf planet in July this year. They document an 80-kilometre strip of the planet's surface, offering an intimate perspective of its cratered, mountainous and glacial terrains. The photos scan from Pluto's jagged horizon about 800 kilometres north-west of the informally named Sputnik Planum, across the al-Idrisi mountains, over the shoreline of Sputnik, and across its icy plains.

On Venus it snows metal
|
view preview
At the very top of Venus’s mountains, below a thick layer of clouds, is snow. But not snow as we know it - with some surfaces reaching 480°C, Venus is way too hot for that. So what is this stuff? Researchers have figured out that Venus's heat is vaporising minerals called galena and bismuthinite, causing them to enter the atmosphere as a metallic mist before condensing into a shiny, metallic frost that rains down on the mountaintops.
