This space wallpaper reveals Galaxy 2MASX J09442693+0429569 imaged by Hubble. This elliptical galaxy has entered a transitional phase from a young, star-forming galaxy to an older, larger, "red and dead" galaxy.
The nine-year-old robot has resumed science operations on the Red Planet.
This beautiful space wallpaper reveals a small, sparkling hook in the dark sky known as J082354.96+280621.6, or J082354.96 for short. It is a starburst galaxy, so named because of the incredibly (and unusually) high rate of star formation occurring within
The robot's handlers have prepared commands designed to get things back to normal.
The storm's eye spans a whopping 1,250 miles.

A planetary system 1200 light years from Earth may contain two worlds entirely covered by global oceans. Kepler 62e and 62f are in the habitable zone of a roughly Sun-like star. Each planet is slightly larger than Earth.
The new Antares rocket is set for a 5 p.m. EDT lift-off.
New findings from a NASA moon probe could lead to safer, more efficient spacecraft.
Experiments done in microgravity are revealing new insights about cell behavior.
Curiosity has been busy since landing on the Red Planet last August.
