In a dramatic ending that marks a beginning in scientific research, NASA's Genesis spacecraft is set to swing by Earth and jettison a sample return capsule filled with particles of the Sun that may ultimately tell us more about the genesis of our solar system.

Aug. 28 Ceremony at Black Rock Mesa for $18 Million Observatory

A team of planet-hunters will announce their discovery of a new class of planets beyond our solar system at a NASA Science Update at 1 p.m. EDT on Tuesday, August 31. Their discovery represents a significant and much-anticipated advance in the hunt for extra-solar planets.

This spectacular image of the supernova remnant Cassiopeia A is the most detailed image ever made of the remains of an exploded star.

In this unusual image, NASA’s Hubble Space Telescope captures a rare view of the celestial equivalent of a geode -- a gas cavity carved by the stellar wind and intense ultraviolet radiation from a hot young star.

These images offer a dramatic look at C153, a galaxy being ripped apart as it races at 4.5 million miles per hour through a distant cluster of galaxies. The infalling galaxy’s gas is being stripped by the pressure of 20-million-degree Celsius gas that permeates the cluster.

Proximity Wins :-)

A team of U.S. astronomers led by James Rhoads from the Space Telescope Science Institute, reports the discovery of extremely high rates of star formation in one of the most distant known galaxies in the universe.

A NASA Chandra X-ray Observatory image has revealed a complex of several intergalactic hot gas clouds in the process of merging. The superb Chandra spatial resolution made it possible to distinguish individual galaxies from the massive clouds of hot gas...

NASA engineers and their industry partners have successfully deployed two solar sails — each nearly 33 feet in length along one side — reaching a critical milestone in the development of a unique propulsion technology that could enable future deep space missions.

Taking out the trash - ISS style...

A new image from NASA's Spitzer Space Telescope shows the shimmering embers of a dying star, and in their midst a mysterious doughnut-shaped ring.

The Cassini spacecraft, which began its tour of the Saturn system just over a month ago, has detected lightning and a new radiation belt at Saturn, and a glow around the planet's largest moon, Titan.

PASADENA, Calif.--Astronomers have identified a new class of cosmic explosions that are more powerful than supernovae but considerably weaker than most gamma-ray bursts. The discovery strongly suggests a continuum between the two previously-known classes of explosions...
