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...

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.

First Science from a Virtual Observatory

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.

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.

Cassini vs. Hubble in a no-holds-barred battle for the Ringed Beauty.

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.

One month into the Gravity Probe B mission — a NASA experiment to test two predictions of Albert Einstein's Theory of General Relativity — all spacecraft subsystems continue to perform well, and the spacecraft orbit is stable. . Gravity Probe B is managed by the Marshall Center...

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...
