Studying molecules in the atmospheres of exoplanets used to be a task reserved for powerful, space-based telescopes. Now, astronomers have used a small, ground-based telescope to identify atmospheric organic molecules on a distant planet. The finding means ground-based telescopes could be used in the hunt for habitable planets.

The Solar Dynamics Observatory (SDO), slated for liftoff on Feb. 9th, will make IMAX-quality movies of solar explosions, peer beneath the stellar surface to see the sun's inner dynamo, and--researchers hope--unravel the mysteries of solar variability.

Nicknamed “snowpocalypse” and “snowmageddon,” an exceptionally severe winter storm dropped several feet of snow around the Washington, D.C., area in early February 2010.

NASA radar imaging flights over Central America, Haiti and the Dominican Republic are in the second week of a three-week campaign.

The Solar Dynamics Observatory is set for an unprecedented mission to study the sun and its dynamic behavior.

America’s ambition to explore space has not come without a human cost. The decisions being made today about our future in space depend on lessons learned from past tragedies.

NASA has released the most detailed and dramatic images ever taken of Pluto. The images from Hubble show an icy, mottled, dark molasses-colored world undergoing seasonal surface color and brightness changes.
