Mini-RF S-band zoom radar image strip through central Mare Serenitatis on the near side of the Moon.

A new study that reconstructed ocean temperatures from millions of years ago could provide new insight into how the Earth responds to climate change.

NASA's Cassini spacecraft has sailed seamlessly through the Nov. 21 flyby of Saturn's moon Enceladus and started transmitting uncalibrated temperature data and images of the rippling terrain.

Why did it take nearly three decades for scientists to create the first global portraits of Earth from NASA's Landsat missions?

Astrobiology Magazine's climate blog, The Hot Zone, recently discussed how receding glaciers could have catastrophic consequences for Earth's climate. Increasing loss of glacial ice will lead to increasing water levels in the oceans. Ultimately, these changes could profoundly affect the biosphere.

Cassini is flying by Saturn's moon Enceladus this weekend for a last peek at the intriguing "tiger stripes" before winter darkness blankets the area for several years.

Sometimes you really can believe your eyes. That's what NASA's STEREO is telling researchers about a controversial phenomenon on the sun known as the solar tsunami.

You don't always have to have a rocket to do rocket science. Sometimes a mere airplane will do – that is, a mere Boeing 747 toting a 17-ton, 9-foot wide telescope named SOFIA.

A proposed space mission that aims to measure dark energy could also detect planets that current surveys are unable to find.
