Hubble Peers Inside a Celestial Geode

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.

Too Fast, Too Furious: A Galaxy's Fatal Plunge

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.

Searching for the end of the cosmic dark ages with GMOS

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.

Chandra catches early phase of cosmic assembly

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 team successfully deploys two solar sail systems

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.

Saturn's Shadow and Titan's Glow Shed Light on a Complex System

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.

Gamma-ray burst of December 3 was a new type of cosmic explosion

Gamma-ray burst of December 3 was a new type of cosmic explosion

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...

Hubble Images Majestic Cousin of the Milky Way

Our Sun and solar system are embedded in a broad pancake of stars deep within the disk of the Milky Way galaxy. Even from a distance, it is impossible to see our galaxy's large-scale features other than the disk...

Stellar Pair Shot Out from Its Birthplace:

Stellar Pair Shot Out from Its Birthplace:

Astronomers studying data from the National Science Foundation's Very Long Baseline Array (VLBA) and other telescopes have concluded that a binary pair of stars forming an energetic microquasar was blasted out of the cluster in which it was born by a supernova explosion some 1.7 million years ago. This is the first time that a fast-moving stellar pair has been tracked back to a specific star cluster.
