When Will History Repeat Itself? (10-31-2007)
Astronomers think that a supernova should go off in our own Milky Way galaxy every 50 years or so. When was the last one we've seen? Probably 1604. Yes, that's over 400 years ago. This being astronomy however, things will undoubtedly average out over the long run, but in the meantime, we're left without a recent supernova in our Galaxy to study. Luckily for us, astronomers from previous centuries were on the case.

From First Light to Eighth Anniversary (08-24-2007)
Chandra's launch aboard the Space Shuttle Columbia on July 23, 1999, was obviously a very important event. However, you might say it wasn't until about a month later that the Chandra mission really got started. In late August, after weeks of getting the spacecraft into the correct orbit and testing out various aspects of the satellite, Chandra was ready for its debut to the public. This was Chandra's First Light. Chandra's director, Dr. Harvey Tananbaum, explains the significance of that early image.

The Bigger They Are, The Harder They Fall (05-24-2007)
When you look at the night sky, stars look like permanent fixtures of light. However, stars are born, live for a period of time, and then ultimately die. How they die is directly linked to how massive they were when they were born.

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.
