Astronomers make first accurate measurement of oxygen in distant galaxy August 3, 2016 Please Register or Log in to view the hidden image! Galaxy COSMOS-1908 is in the center of this Hubble Space Telescope image, indicated by the arrow. Nearly everything in the image is a galaxy; many of these galaxies are much closer to the Earth than COSMOS-1908. Credit: Ryan Sanders and the CANDELS team UCLA astronomers have made the first accurate measurement of the abundance of oxygen in a distant galaxy. Oxygen, the third-most abundant chemical element in the universe, is created inside stars and released into interstellar gas when stars die. Quantifying the amount of oxygen is key to understanding how matter cycles in and out of galaxies. Read more at: http://phys.org/news/2016-08-astronomers-accurate-oxygen-distant-galaxy.html#jCp
