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...

Thanks to new images by the Chandra X-ray observatory, the giant galaxy's violent past comes into focus...

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...

University of Hawaii Astronomer and Colleagues Find Evidence That Asteroids Change Color as They Age

Like most creation stories, this one is dramatic: we began, not as a mere glimmer buried in an obscure cloud, but instead amidst the glare and turmoil of restless giants...

A pulsar works like a lighthouse, in which the light may be on all the time, but it appears to blink on and off. Scientists were surprised to find that the B pulsar is on only at certain locations in its orbit. "It's as though something is turning B on and off...

Sharpless 140 and NGC300 in all their glory

If approved, the Dark Energy Survey would measure the history of the expansion rate of the universe more precisely than ever before, using the largest camera ever built with Charge Coupled Devices (CCD). The 500 megapixel Dark Energy Camera would be placed on an existing 4-meter telescope located in north-central Chile at the National Optical Astronomy Observatory's Cerro Tololo Inter-American Observatory.

Looking for a very cool astronomical education site for kids? One that even adults will be mesmerized by? The recently unveiled “Cool Cosmos” portal is involving students in science with multi-disciplinary educational materials produced with the goal of engaging the young minds of future generations of scientists.
