Studying the Martian climate is important as it helps us understand how a planet that was originally similar to Earth turned out so very different.

New images from NASA's Cassini spacecraft reveal a giant cyclone at Saturn's north pole, and show that a similarly monstrous cyclone churning at Saturn's south pole is powered by Earth-like storm patterns.

Scientists have discovered a giant cyclone swirling on Saturn's north pole, and observed a similar storm on the planet's south pole in detail 10 times greater than before, thanks to new images from NASA's Cassini spacecraft.

South Pole telescope offers fresh views of Universe's expansion.

From the outside, the model lunar habitat at NASA's Langley Research Center looks like a futuristic igloo. The inside looks more like a space-age dorm room equipped with a laptop, magazines and a tiny shower -- everything an astronaut would need

The Exoplanet Task Force of the Astronomy and Astrophysics Advisory Committee has released its report detailing a strategy for obtaining the first detection and characterization of Earth-like planets around other stars within 15 years

Astronomers are announcing that the precise gravity field of the lunar far side and the global lunar topography map were obtained by KAGUYA spacecraft.

The Cassini orbiter took this picture of the Saturnian moon Enceladus taken during Thursday's flyby. The Cassini orbiter came through its closest-ever encounter with a Saturnian moon with flying colors - and with

An ambitious project to track down small, icy bodies circling in the far reaches of the solar system has gone cold. Apparently, Kuiper Belt objects (KBOs) between two and 17 miles in diameter don't exist.
