Here is the likelihood that this is just chance.  And from statistics class, or just plain common sense it sure seems that the observation has rhyme and reason to it!

This implies that the ring is more than 5 billion light-years across, and, according to the team, there is only a 1 in 20,000 probability of the GRBs being in this distribution by chance.

And below is a cool video of these gamma ray bursts described as such:

An artist’s conception of the environment around GRB 020819B based on ALMA observations. The GRB occurred in an arm of a galaxy in the constellation of Pisces (The Fishes). GRBs are huge explosions of a star spouting high-speed jets in a direction toward the observer. In a complete surprise, less gas was observed than expected, and correspondingly much more dust, making some GRBs appear as “dark GRBs”.

We hope you like the video and I am curious to see if astronomers will come up with more meaning about this surprising observation.
