The Largest Feature In The Universe

Astronomers have discovered the largest possible feature in the known universe. The feature is a ring of nine gamma ray bursts, five billion light years across. Gamma-ray bursts (GRBs) are the most incandescent*incandescent*

occurrences in the universe. They release as much energy in a few seconds as the Sun does over its 10 billion year lifetime.

This occurs as a result of enormous stars collapsing in to black holes, and the luminosity generated by them guides the astronomers to map the location of distant galaxies. The feature that has been discovered was observed using multiple space-and-ground-based observations.

Researchers suggest GRBs seem to be at very similar distances from us – around 7 billion light years in a circle more than 70 times the diameter of the full moon. This entails that the ring is more than 5 billion light years across. Professor Lajos Balazs of Konkoly Observatory in Budapest said there is only a 1 in 20,000 probability of the GRBs being in this distribution by chance.”
