Astronomers have used data from three of NASA's Great Observatories to make the most detailed study yet of an extremely massive young galaxy cluster. This rare cluster, which is located 10 billion light years from Earth, weighs as much as 500 trillion Suns. This object has important implications for understanding how these megastructures formed and evolved early in the Universe. The galaxy cluster called IDCS J1426.5+3508 (IDCS 1426 for short), is so far away that the light detected is from when the universe was roughly a quarter of its current age. It is the most massive galaxy cluster detected at such an early age. First discovered by the Spitzer Space Telescope in 2012, IDCS 1426 was observed using the Hubble Space Telescope and the Keck Observatory to determine its distance. Observations from the Combined Array for Millimeter Wave Astronomy indicated it was extremely massive. New data from the Chandra X-ray Observatory confirm the galaxy cluster mass and show that about 90% of the mass of the cluster is in the form of dark matter, a mysterious substance detected so far only through its gravitational pull on normal matter composed of atoms. “We are really pushing the boundaries with this discovery,” said Mark Brodwin of the University of Missouri at Kansas City, who led the study. “As one of the earliest massive structures to form in the Universe, this cluster sets a high bar for theories that attempt to explain how clusters and galaxies evolve. #NASA #chandra - January 08, 2016 at 01:04AM Source: https://scontent.cdninstagram.com/hphotos-xpf1/t51.2885-15/sh0.08/e35/11267382_1723324997900784_1791889298_n.jpg #nasa #space #iss #isro #mars #marsorbiter #outerspace #lightyears #milkyway #universe #galaxy #stars #sun #moon #saturn #jupiter #stumble #stumblespace
