Sun's Almost Perfectly Round Shape Baffles ScientistsThe Sun is nearly the roundest object ever measured. If scaled to the size of a beach ball, it would be so round that the difference between the widest and narrow diameters would be much less than the width of a human hair.

Sad Photos: Rockwell Downey Building 1 Demolition

Kepler: The Long Road to Other Worlds

Looking for planets hundreds of light-years away is tricky. The stars are very big and bright, the planets very small and faint. Locating them requires staring at stars for a long time in hopes of everything aligning just right so we can witness a planet's transit--that is, its passage in front of its star, which obscures a tiny fraction of the star's light. Measuring that dip in light is how the Kepler mission determines a planet's size.

NASA Kicks Off Asteroid Simulation; Media Invited to Observe

The Research and Technology Studies (RATS) test, a 10-day asteroid exploration simulation in Johnson's Space Vehicle Mockup Facility, kicked off this week. As NASA makes plans to send humans to asteroids by 2025, RATS and other mission simulations provide the agency with a way to test new operations, concepts and exploration techniques to influence the future of exploration.

Voyager at 35 - Break on Through to the Other Side

Voyager 2 became the longest-operating spacecraft on Aug. 13, 2012, surpassing Pioneer 6, which launched on Dec. 16, 1965, and sent its last signal back to NASA's Deep Space Network on Dec. 8, 2000. (It operated for 12,758 days.)

Digging deep: New Mars mission to take first look at what's going on deep inside the Red Planet

A UK Space Agency-funded instrument, designed to investigate the interior structure and processes of Mars, has been selected to travel to the Red Planet on NASA's newly announced InSight mission.
