The Wide Field Imager on the MPG/ESO 2.2-meter telescope at the La Silla Observatory has imaged a region of star formation called NGC 3324. The intense radiation from several of NGC 3324's massive, blue-white stars has carved out a cavity in the surrounding gas and dust.

2011 was a year of farewells in space: an end to the space shuttle program ... NASA's official abandonment of the Spirit rover on Mars ... and the leavetaking of NASA's next Mars rover. This unprecedented image shows a different kind of leavetaking. Italian astronaut Paolo Nespoli snapped the picture of Endeavour docked to the International Space Station on May 23 as he was leaving in a Soyuz spacecraft. This was the only opportunity to photograph the space station and shuttle together from an orbital vantage point.

This week, Boing Boing was invited to visit NASA's Jet Propulsion Laboratory for the first and only opportunity for media to enter the Pasadena, CA clean room where NASA's next Mars rover, Curiosity, and other components of the Mars Science Laboratory spacecraft have been built for launch in late 2011 from Florida.
Shipment from the clean room to Florida will begin next month. Curiosity rover recently completed tests under simulated space and Mars-surface environmental conditions in another building and is back in the Spacecraft Assembly Facility at NASA's Jet Propulsion Laboratory for other tests. Spacecraft assembly and testing specialists showed Boing Boing the rover and the other spacecraft components, including the descent stage "sky crane."
Photographer Joseph Linaschke visited on behalf of Boing Boing (he donned a bunny suit for the occasion) and shot this series of photos. More below.

satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be either polar orbiting, seeing the same swath of the Earth every 12 hours, or geostationary, hovering over the same spot on Earth by orbiting over the equator while moving at the speed of the Earth's rotation. These meteorological satellites, however, see more than clouds and cloud systems.
