‘Supervoid’ Is 1.8 Bn Light-Years Across, The Largest Single Structure In Universe – Study – 21 April 2015

RT logoAstronomers have discovered a vast supervoid measuring 1.8 billion light-years across. They believe this will provide new insight into the remaining mysteries of the Big Bang.

The massive spherical blob known as the supervoid may be “the largest individual structure ever identified by humanity,” according to lead researcher for the project, István Szapudi, of the Institute for Astronomy at the University of Hawaiʻi at Mānoa.

“Using data from Hawaii’s Pan-STARRS1 (PS1) telescope located on Haleakala, Maui, and NASA’s Wide Field Survey Explorer (WISE) satellite, Szapudi’s team discovered a large supervoid, a vast region 1.8 billion light-years across, in which the density of galaxies is much lower than usual in the known universe,” a press release stated.

“This void was found by combining observations taken by PS1 at optical wavelengths with observations taken by WISE at infrared wavelengths to estimate the distance to and position of each galaxy in that part of the sky.”
