This beautiful picture of the planetary nebula Kohoutek 4-55, taken on May 4, was the last image delivered by the Hubble Space Telescope's Wide Field and Planetary Camera 2, the instrument credited with saving the once-troubled observatory. Spacewalkers from the shuttle Atlantis replaced the 16-year-old camera with a new instrument.

Hi, neighbor!This image, released April 28, blends the Galaxy Evolution Explorer's ultraviolet view of the galaxy M33 and an infrared view from NASA's Spitzer Space Telescope. M33, one of our closest galactic neighbors, is about 2.9 million light-years away in the constellation Triangulum, part of what's known as our Local Group of galaxies.
Message from Mercury
New observations from NASA's Messenger spacecraft reveal never-before-seen portions of Mercury, including a giant impact crater that spans a length equivalent to the distance between Washington and Boston. This imagery was acquired in 2008 and published in the May 1 issue of the journal Science.
