The small constellation Sagitta sports this large piece of cosmic jewelry, dubbed the Necklace Nebula. The newly discovered example of a ring-shaped planetary nebula is about 15,000 light-years away.

Comet Hartley 2 can be seen from NASA's EPOXI mission November 4, 2010 in space. The image was taken from a distance of about 435 miles.
This Landsat image features the heart-shaped Small Aral Sea (or North Aral Sea), the former northern basin of the Aral Sea that once supported a vibrant economy in Central Asia.
Still waiting for the green light, the Space Shuttle Discovery sits on launch pad 39-a in Cape Canaveral, Florida, where it's waiting to set off on its final scheduled mission.

ESA's ERS-2 and Envisat satellites were paired up for a final tandem campaign in 2010. Data from this final duet are being used to generate 3D models of glaciers and low-lying coastal areas.
The Robonaut 2 meets the press. The first humanoid robot ever bound for space, this $2.5 million mechanical and electrical marvel will accompany Discovery on a one-way ride to the International Space Station. The hope is that the Robonaut eventually will assume a myriad of space station cleaning duties - and perhaps even work outside the ISS, holding tools for spacewalking astronauts.
