HERE IS HOW THEY SLEEP IN SPACE
But that is the coolest closet in the universe, I promise you.
Giant Black Hole at Milky Way's Core 'Cooking' Gas
This was seen by the Herschel Space Observatory, which is being retired soon. That's too bad, but it's had a good run.

It ran out of liquid helium coolant. This sort of makes me want to cry.
Here is a space-mouse.

Wow! Man, people really want to go to space.
The Hubble Telescope recently caught this amazing image of a supernova remnant, which is delightfully known as "SNR-B0519-69.0" (we astronomers are renowned for our catchy-naming skills).
Regardless of it's crappy name, it is a striking image. The red whispy shells we see are the outer layers of the star in the centre, mostly hydrogen and some helium with a few heavier elements, which have been expelled out into space in a massive explosion at the end of the star's life. The star which is in the centre of the bubble is now a White Dwarf star, and fusion has ceased in its core, so over the next few hundred million years the star will cool down and fade away, becoming a dead Black Dwarf star. This is how our own Sun's life will end, but not before it takes out half of the Solar System, when it first enlarges to Red Giant status. Not, to worry though, our Sun is only around the middle of it's time in the Main Sequence, so we have many billions of years before we should get concerned.
If anyone would like to learn more about the lives of the stars, may I recommend reading this:

And watching this:
Now, from the death of a star, to the birth of millions of them. Scientists have recently discovered the most efficient galaxy ever studied, SDSSJ1506+54 (another very catchy name, good job guys!).
This green-tinged galaxy is converting gas into stars at a rate previously thought to be the absolute maximum rate possible, in perfect conditions in an isolated system. In reality however, it would seem unlikely to actually find a galaxy doing this because we so rarely see "perfect systems" in the real world. This galaxy was discovered using infra-red telescope WISE, and when we trained our visible-spectrum telescopes on it, it was apparent that millions of stars are being created in a very compact area, only a few hundred light years across. It is spitting out baby stars hundreds of times faster than the Milky-Way. This baby-boom won't last though, as the galaxy is rapidly using up it's star making fuel, and will soon (just 30 million years!) settle down into a massive elliptical galaxy.
It is thought that this star making binge was initiated when two galaxies collided, igniting gas clouds and triggering just all the star formation.
Wait, green-coloured, and a massive family? Must be an Irish galaxy.

Holy crap, guys, this was awesome! Tell your friends on facebook and twitter or whatever.
