Galaxy Cluster Is a Cosmic Magnifying Glass for Hubble Telescope
Galaxy Cluster Is a Cosmic Magnifying Glass for Hubble Telescope
   A new image from the Hubble Space Telescope reveals a Galaxy Cluster so huge that it acts like a Magnifying glass, warping and amplifying light from galaxies much farther away. The new Hubble telescope photo shows the Galaxy Cluster MACS J0454.1-0300, which is so massive it is the equivalent of about 180 trillion suns. For comparison, the sun is about 333,000 times the mass of the Earth. In this image, released last week, the Cluster magnifies galaxies that would be too faint to be detected **rmally with today's tech**logy. These faraway galaxies, each containing millions or billions of stars, appear as sweeping, elongated arcs to the left of this image, NASA officials said. This Magnifying process is k**wn as gravitational lensing. Read more...
