By examining a cloud of exploded remains, NASA's Chandra X-ray Observatory has "carded" a supernova remnant to reveal its underage status. At a mere 140 years old, G1.9+0.3 is the youngest known supernova remnant in the Milky Way. The materials surrounding it are still expanding at almost 35 million miles per hour, an unprecedented speed for a supernova remnant.

Exploring the Invisible Universe: Chandra X-ray Observatory

The Chandra X-ray Observatory is part of NASA's fleet of "Great Observatories" along with the Hubble Space Telescope, the Spitizer Space Telescope and the now deorbited Compton Gamma Ray Observatory. Chandra allows scientists from around the world to obtain unprecedented X-ray images of exotic environments to help understand the structure and evolution of the universe. Already surpassing its five-year life, NASA's Chandra X-ray Observatory is rewriting textbooks and helping advance technology.

Chandra X-ray Center

The Smithsonian Astrophysical Observatory (SAO) in Cambridge, Mass., is responsible for the conduct of the day-to-day flight operations and science activities from the Operations Control Center and Chandra X-ray Center (CXC) facilities. SAO also coordinates science planning for the observing program and provides user support as science products are made available to the scientific community. The CXC Web site is the primary resource for information on the Chanda X-ray Observatory mission, providing comprehensive materials such as news releases, photos, status reports, mission background materials, etc.
