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.

Mergers And Acquisitions In The Cosmos (06-28-2007)
News about mergers is usually found in the business section. But many objects in the Universe, from black holes to clusters of galaxies, are also prone to mergers. Like the corporate world, cosmic mergers are dictated by where the most assets lie.
