The Upgraded Hubble Telescope

If you weren't aware, in may this year NASA/ESA sent a bunch of astronauts up to work on the Hubble Space Telescope. The mission was 13 days longs and they replaced several vital parts of the telescope to hopefully give us a better view of the cosmos than we've ever had before.
Just this month, some of the first images sent to us from the upgraded Hubble were released.

This image I put at the top of the post has become known as the butterfly nebula, for obvious reasons. It used to be a star about five times the volume of our sun, but it exploded.

If you're interested in more pictures like this (in MUCH higher resolutions) with more detailed explanations of what is happening in them, go and visit Spacetelescope.org
