A Black Hole Story Told by a Cosmic Blob and Bubble

IC 2497
Two cosmic structures show evidence for a remarkable change in behavior of a supermassive black hole in a distant galaxy. Using data from NASA’s Chandra X-ray Observatory and other telescopes, astronomers are piecing together clues from a cosmic “blob” and a gas bubble that could be a new way to probe the past activity of a giant black hole and its effect on its host galaxy.

On August 5th, the 2016 Olympic Summer Games will begin with the Opening Ceremonies in Rio de Janeiro, Brazil. A new project from NASA’s Chandra X-ray Observatory and its Communications group takes a look at the amazing feats performed by Olympic athletes and tries to provide context for them in an innovative way.

Birthdays can be a lot of fun and most teenagers can’t wait to turn sixteen. After all, this birthday often marks new adventures and opportunities (not to mention, maybe a party!)

Today we are celebrating the “sweet 16th” birthday not of a person, but of NASA's Chandra X-ray Observatory. On July 23, 1999, Chandra was launched into space aboard the Space Shuttle Columbia and has been working diligently to explore the high-energy Universe ever since.

Chandra, me, and the number 23

A month or two after Chandra launched in July 1999, I was asked at a Chandra X-ray Center (CXC) senior staff meeting how long I actually expected Chandra to operate. I spontaneously responded: "23 years". Now that is a number not heard very frequently, so there were lots of quizzical looks indicating that an explanation was in order.

LUCKY 13

A little bit after midnight (12:31 am EDT to be exact) on July 23, 1999, the Space Shuttle Columbia lifted off from the Kennedy Space Center in Florida. Onboard was what was then the largest payload ever carried by a Shuttle: the Chandra X-ray Observatory.
