NASA completes first part of Webb Telescope's 'eye surgery' operation Posted: 15 May 2013 02:52 PM PDT Much like the inside of an operating room, in the clean room at NASA's Goddard Space Flight Center in Greenbelt, Md., engineers worked meticulously to implant part of the eyes of the James Webb Space Telescope. They scrubbed up and suited up to perform one of the most delicate performances of their lives. That part of the eyes, the MIRI, or Mid-Infrared Instrument, will glimpse the formation of galaxies and see deeper into the universe than ever before.

New craters abound: Mars camera reveals hundreds of impacts each year Posted: 15 May 2013 01:50 PM PDT Taking before and after pictures of the Martian terrain, researchers have identified nearly 250 fresh impact craters on the Red Planet. The results provide scientists with a better yardstick to estimate how frequently craters are blasted on Mars, allowing them to assess recently formed features with greater accuracy.

Scientists shape first global topographic map of Saturn's moon Titan Posted: 15 May 2013 01:39 PM PDT Scientists have created the first global topographic map of Saturn's moon Titan, giving researchers a valuable tool for learning more about one of the most Earthlike and interesting worlds in the solar system.

Black hole powered jets plow into galaxy Posted: 15 May 2013 12:14 PM PDT The intense gravity of a supermassive black hole can be tapped to produce immense power in the form of jets moving at millions of miles per hour.
