Wall Divides East and West Sides of Cosmic Metropolis

A new study unveils NGC 604, the largest region of star formation in the nearby galaxy M33, in its first deep, high-resolution view in X-rays. This composite image from Chandra X-ray Observatory data (colored blue), combined with optical light data from the Hubble Space Telescope (red and green), shows a divided neighborhood where some 200 hot, young, massive stars reside.

Introducing Chandra's Video Blog

While we like the written word as much as the next person, we thought it would be good to mix things up. We recently got a new, small, handheld video camera (about the size of a cell phone). The plan is to use this to add simple videos to the Chandra blog and other places on the website. Because it's handheld and very sensitive, it's easy for the videos to appear shaky and the sound is not perfect. We'll work on this for the future.

Ushering in IYA2009, Chandra-Style

There are some exciting, yet different, Chandra-related events happening at the American Astronomical Society (https://aas.org/) meeting in Long Beach, CA today. First, there was a press conference this morning to announce new results on Cassiopeia A that bring this supernova remnant "to life". One result shows how Cas A has changed from 2000 - just after Chandra's launch - through until late 2007. This is the first time scientists have been able to watch as a supernova remnant changes like this over time.

Last minute E-carding

It sounds like a good portion of the United States got walloped over the weekend with snow and ice and seemingly everything in between. (Yesterday was, after all, the winter solstice and the official start of the season, so what else should we have expected?) While the white stuff can be beautiful, it can also put a damper on holiday errands. For those of us who might be lagging behind on getting their holiday cards in the mail, we here at Chandra can help you out. We've put together a bunch of e-cards that, almost magically, do not involve the Post Office in order to get delivered.

Doing More with More

Back in 2002, we released a colorful image of the star-forming region known as 30 Doradus (also called the Tarantula Nebula.) At the time, we thought it was a beautiful image - and it was - of this pocket of intense stellar birth and death in the neighboring Large Magellanic Cloud.
