XMM-Newton spacecraft finds most distant quasar
Quasars are the most luminous known objects in the Universe. They can emit 1000 times the energy of our entire Galaxy, and this prodigious luminosity originates from objects only the size of our solar system. XMM-Newton has detected the X-rays of the most distant known quasar, providing a view of the Universe when it was less than 1 billion years old.

Global Surveyor captures spring thaw on Mars
A newly-released color image from NASA's Mars Global Surveyor spacecraft in orbit around the Red Planet shows the surface thawing in springtime. Beneath the frost some areas get warmer while others stay cold, causing frost to linger in parts and sublime away elsewhere. Dazzling, almost psychadelic patterns are the result.
