Single telescope discovers 72 new galaxies
Astronomers have discovered 72 galaxies using ESO's Very Large Telescope (VLT) in Chile as part of the deepest spectroscopic survey ever conducted. VLT used an instrument which split light into its component colours to create a spectrum. This allows measurement of distance, colours and other properties of galaxies which went undetected even by NASA's Hubble Space Telescope, said astronomers.
