By Leonidas Papadopoulos, on August 19th, 2015 A composite image of a galaxy as seen in different wavelengths by the GAMA survey. The results of the survey, which studied more than 200,000 galaxies in the local Universe, revealed that the latter’s total energy output has decreased by at least 50 percent during the last 2 billion years.
