Largest Thing In Universe: A Supervoid 1.3 Billion Light Years Across
Astronomers may have found “the largest individual structure ever identified by humanity”, according to Dr István Szapudi of the University of Hawaii at Manoa. Dr Szapudi and his team report their findings in the journal Monthly Notices of the Royal Astronomical Society.
A map of the cosmic microwave background made using the Planck satellite. The Cold Spot, the ellipse at the bottom right, area resides in the constellation Eridanus in the southern galactic hemisphere. The insets show the environment of this anomalous patch of the sky, as mapped by Szapudi’s team using PS1 and WISE data and as observed in the cosmic microwave background temperature data. The angular diameter of the vast supervoid aligned with the Cold Spot, which exceeds 30 degrees, is marked by the white circles.
