Where the moon gets its warmth isn't understood. Another moon of more or less the same size and distance from Saturn is completely dead.
The inflation theory has come under attack recently by scientists who claim that it's not needed to explain why the universe is as uniform as it is. In March new data was recorded by a microwave observatory at the South Pole that seems to confirm the inflation theory. The findings are controversial and the facts are still being checked.
Here's (above) an odd one: a galaxy that's tearing itself apart from the inside. Not much star formation is visible in the pinwheel, but lots of recently created star clusters appear in the matter ejected from the galaxy.
Above, the Great Nebula in Orion, about 1500 light years away. It's in the same spiral arm that we inhabit. The colors are unfortunately false. They're added to code temperature and composition.

Really interesting! I'd like to look into more of those controversial debates, especially over the inflation theory a bit more.
