Headf*** ahoy....

Astronomers have found a structure in the universe so huge, that current cosmological theory says it shouldn't exist

A US-Hungarian team recently discovered a ring of nine gamma ray bursts, in nine distant galaxies, 5 billion light years across.

For comparison, our galaxy is just a hundred thousand light-years across.

Gamma-ray bursts are the brightest objects in the universe, releasing as much energy in a few seconds as the sun does over its 10 billion year lifetime.

Recent evidence from recent satellites like Swift and Fermi indicate that the energy behind a gamma-ray burst comes from the collapse of matter into a black hole.

Their huge luminosity helps astronomers to map out the location of distant galaxies, something the team exploited to find the structure.

The Gamma-ray bursts (GRBs) that make up the newly discovered ring were seen using a combination of space- and ground-based observatories.

They appear to be at very similar distances from us around seven billion light years in a circle 36 across on the sky, or more than 70 times the diameter of the full moon.

This suggests that the ring is more than 5 billion light years across.

The structure also defies a widely accepted cosmological principle, which says that the universe would look uniform when observed at the largest scales.

Why do they consider it a structure rather than 9 separate galaxies with GRBs in them

It was a UFO in that it was unidentified. It wasn't an alien.

It was space junk. Earth's orbit is litered with the stuff.

EDIT - just seen it's a new one, a red glow.

Aliens' visiting us here do not exist. Anyone with even a basic understanding of the vastness of space and distances know it isn't possible.

Aliens might be united fans so had travelled over for the match

Seen a couple of shooting stars already from tonight's show apparently should peak in about 20 mins.

If you don't know where to look, Google's Sky Map app is awesome. Look for Perseids to the north east
