Chandra Deep Field South

astronomical survey in the constellation Fornax

The Chandra Deep Field South (CDF-S) is an image taken by the Chandra X-ray Observatory satellite.

Three-colour composite image of the Chandra Deep Field South (CDF-S), got with the Wide Field Imager on the 2.2-m MPG/ESO telescope at the ESO La Silla Observatory (Chile).

The location has, like the Lockman Hole, a relatively clear "window" through the clouds of neutral hydrogen gas in our Milky Way galaxy. This allows us to clearly see the rest of the universe in X-rays.[1]

The image is centered on a patch of sky in the Southern Hemisphere Fornax constellation.[2] This region was selected because it has much less galactic gas and dust to obscure distant sources.[3]

More observations was taken between 2000 and 2010.[4] The Chandra Deep Field South is the single target where Chandra has observed the longest.
