Hubble discovers 67 more galaxiesFebruary 20th, 2008 - 12:25 pm ICT by admin
New York, February 20 (IANS) The Hubble space telescope has discovered 67 “lensing” galaxies in the distant universe, under the massive COSMOS project to map space. Gravitational lensing occurs when light travelling towards us from a distant galaxy is magnified and distorted by unusually huge clusters of other galaxies.
The “lenses” often allow astronomers to peer much further back into the early universe. They come from a recent set of observations, part of a project to survey a stretch of sky nine times the size of the full moon, facilitated by a host of space and earth-based observatories.
The COSMOS project, led by Nick Scoville of the California Institute of Technology, used, among others, the Hubble Space Telescope, as well as the Spitzer Space Telescope and the Chandra X-ray Observatory.
