NASA is preparing the final—and very risky—Hubble maintenance mission. They have released an interactive site to explain it, which includes some of my favoriter favoritest Hubble images ever, ready for desktop background use:

NASA also released a new image to commemorate the space telescope's 19 birthday. This is Arp 194, a system containing several interacting galaxies with a "cosmic fountain" of stars, gas, dust, and milk shakes that stretches 100,000 light-years.

I don't know about you, but I can't have enough of these. Actually, I think I'm going to sneak into NY's Hayden Planetarium this weekend. [NASA]
