What's in a Name? (01-02-2008)
Names in astronomy don't always tell the whole story. Let's take, for example, radio galaxies. Why, might you ask, would a Chandra podcast talk about such an object? The answer is that radio galaxies are, yes, very bright in radio emission. But they are also powerful emitters of X-rays, optical light and from other parts of the electromagnetic spectrum. More than that, they are important objects that really have played a very big role in how the Universe has evolved.

The Truth and Lies about Black Holes (11-30-2007)
Black holes have a bad reputation. After all, something that could swallow you completely sounds pretty scary. They're invisible, so maybe there's one just around the corner and we dont know it! Also, arent they enormous vacuum cleaners capable of destroying anything that gets near them? Once the black hole starts pulling on something, isnt that just a one-way ticket to oblivion? Well, not all of these things are exactly true.

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.

In A Galaxy Far, Far Away and Also Those Nearby (09-28-2007)
"In a galaxy far, far away..." These are some of the most famous words in movie history. But what do we already know about galaxies, and what do astronomers, like those using the Chandra X- ray Observatory, still hope to learn about them?

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.
