Hubble Astronomers Use Supernovae to Gauge Power of Cosmic Lenses
Distant exploding stars observed by NASA’s Hubble Space Telescope are providing astronomers with a powerful tool to determine the strength of naturally-occurring “cosmic lenses” that are used to magnify objects in the remote universe.
Two teams of astronomers, working independently, observed three such exploding stars, called supernovae. Their light was amplified by the immense gravity of massive galaxy clusters in the foreground — a phenomenon called gravitational lensing. Astronomers use the gravitational lensing effect to search for distant objects that might otherwise be too faint to see, even with today’s largest telescopes.

Overview: 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 X-ray images of exotic environments to help understand the structure and evolution of the universe. The Chandra X-ray Observatory program is managed by NASA’s Marshall Center for the Science Mission Directorate, NASA Headquarters, Washington, D.C.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. The CXC Web site is the primary resource for information on the Chanda X-ray Observatory mission.
