Galaxy Cleaned Out by Encounter with Hot Cluster Gas

New observations from the WIYN 3.5-meter telescope on Kitt Peak show striking visual evidence for a galaxy being stripped bare of its star-forming material by its violent ongoing encounter with the hot gas in the center of a galaxy cluster...

Smoking gun found for gamma-ray burst in Milky Way

Data from NASA's Chandra X-ray Observatory, along with infrared observations, have uncovered evidence that a gamma-ray burst — one of nature's most cataclysmic events — occurred in our Milky Way Galaxy a few thousand years ago. The Marshall Center manages the Chandra program.

Raw Ingredients for Life Detected in Planetary Construction Zones

NASA has announced new findings from the Spitzer Space Telescope, including the discovery of significant amounts of icy organic materials sprinkled throughout several "planetary construction zones," or dusty planet-forming discs, which circle infant stars.

Milky Way Churning Out New Stars at a Furious Pace

Using NASA's Spitzer Space Telescope, astronomers have found in RCW49 more than 300 newborn or 'protostars,' all with circumstellar disks of dust and gas. The discovery reveals that galaxies make new stars at a much more prolific rate than previously imagined. The stelar disks of dust and gas not only feed material onto the growing new stars, but can be the raw material for new planetary systems.

Chandra reveals two faces of supernova power

The NASA Chandra X-ray Observatory image of SNR 0540-69.3 clearly shows two aspects of the enormous power released when a massive star explodes. An implosion crushed material into an extremely dense (10 miles in diameter) neutron star, triggering an explosion that sent a shock wave rumbling through space at speeds in excess of 5 million mph.

Chandra Opens New Line Of Investigation On Dark Energy

Astronomers have detected and probed dark energy by applying a powerful, new method that uses images of galaxy clusters made by NASA's Chandra X-ray Observatory. The results trace the transition of the expansion of the universe from a decelerating to an accelerating phase several billion years ago...
