The Crab Nebula in 60 Seconds (03-31-2008)
In 1054 A.D., a star's death in the constellation Taurus was observed on Earth. Now, almost a thousand years later, a superdense neutron star left behind by the explosion is spewing out a blizzard of extremely high-energy particles into the expanding debris field known as the Crab Nebula.

The Universe Darkly (02-29-2008)
When you look up at the night sky, you see a lot of things glowing like stars, planets, and galaxies. So it might sound strange to hear that most of the Universe is actually dark. The truth is the protons, neutrons and electrons that make up everything we can see, and that means everything with telescopes we've got, accounts for only about 4% of the mass and energy of the Universe. The rest is dark and mysterious. More specifically, about 70% of the Universe is what is known as dark energy; about 26% is so-called dark matter. Modern day astronomers have developed many tactics to explore the dark Universe, including using telescopes like Chandra.

Chandra in the (Google) Sky (01-29-2008)
Astronomy is truly in a golden age. With a fleet of space-based observatories, including the Chandra X-ray Observatory, astronomers now have a suite of amazing tools to study the Universe. Simultaneously to this bonanza in astronomy has been the growth and expansion of the Internet. Think back to before 1990. The Internet was barely a rumor and there were no Great Observatories! But now people are taking advantage of these two seemingly separate advances to do some amazing things
