#Astronomy: An international team of astronomers, led by David Sobral from Leinden University of the Netherlands used three telescopes located across the globe to study the trends in star formation, from the earliest stars that made up the first galaxies in the universe, up until now. Their findings suggests something quite shocking .. almost 95% of stars that will ever live have already been born!
Astronomers used to think the universe contains 100-200 billion galaxies. Now, the population estimate has jumped up to 2 trillion. (NASA, ESA, G. Illingworth, D. Magee, and P. Oesch (University of California, Santa Cruz), R. Bouwens (Leiden University), and the HUDF09 Team)
Called the eXtreme Deep Field, or XDF, the photo was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full Moon. Image released September 25, 2012.
