A Tour of Eta Carinae
A Tour of Eta Carinae
New Chandra data are helping astronomers better understand how the two stars in Eta Carinae interact with one another through powerful winds blowing off their surfaces. (2014-08-27)


Galactic Center in 60 Seconds

View/Listen
Narrator (Megan Watzke, CXC): This image from the Chandra X-ray Observatory reveals a wealth of exotic objects and high-energy features at the center of our Milky Way galaxy. In this new and deep image from Chandra, red represents lower-energy X-rays, green shows the medium range, and blue indicates the higher-energy X-rays Chandra can detect. The hundreds of small dots show emission from material around black holes and other dense stellar objects like neutron stars. A supermassive black hole -- some four million times more massive than the Sun -- resides within the bright region to the right of center. The diffuse X-ray light comes from gas heated to millions of degrees by outflows from the supermassive black hole, winds from giant stars, and stellar explosions.
