Just Two Numbers Is All You Need (06-02-2008)
Black holes sound wildly complicated. After all, there are all sorts of bizarre things going on: intense gravity, the warping of the fabric of space, the distortion of time itself. But when it comes to describing black holes, it comes down to just two numbers: the mass of the black hole and its spin.

Exploring The Large Magellanic Cloud (04-02-2008)
The Large Magellanic Cloud, known as the LMC, is a nearby satellite galaxy of our own Milky Way. At a distance of around 160,000 light-years, the LMC is the third closest galaxy to us. But the LMC is more than just a nice little sidekick.

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
