Snowball Fight in the Solar System (01-22-2007)
One of the most surprising objects observed in X-rays are comets. X-rays are normally associated with the hottest things in the Universe, such as black holes. Comets, however, were described by Fred Whipple as being "dirty snowballs". So how does a snowball make X-rays?

Black Holes: Tall, Grande, Venti (12-31-2006)
Long before astronomers found evidence that black holes existed, these exotic objects have captured imaginations. In the 21st century, scientists not only have proof that black holes are real, they continue to make startling discoveries both about individual black holes examples and about their populations across the Universe.

Giants of the Universe Probe Cosmic Questions (11-30-2006)
Clusters of galaxies are the largest structures in the Universe that are held together by gravity. Because of their immense size and mass, galaxy clusters are extremely useful as tools to probe a variety of questions about the Universe as a whole as well as properties of the clusters themselves.

Supernovas: When Stars Die (10-30-2006)
When a star explodes, it leaves behind a debris field of stellar material and high-energy particles known as a supernova remnant. Astronomers use Chandra to study these remnants that can produce intense X-ray radiation for thousands of years. Supernova remnants are responsible for seeding cloud that formed our Sun, planets, and ultimately us with elements like nitrogen and oxygen.
