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.

Until Their Dying Day: Stars on the Brink (09-26-2006)
Supernovas are the remnants of catastrophic explosions, and they are among the favorite targets of scientists who use Chandra, for good reason too. Supernovas and their remnants have proven to be extremely important in understanding topics ranging from the birth of our Solar System to the history and composition of the Universe itself.

Peering into the Heart of the Milky Way (08-31-2006)
Humanity has long sought to learn about the Milky Way, our home galaxy. Even after the advent of optical telescopes, the Milky Way's center remained mysterious because gas and dust blocks most visible light along our line of sight. Fortunately, X-ray telescopes like Chandra can detect higher-energy radiation that penetrates this veil of galactic debris.
