The cosmos is the stage for a variety of giant explosions.

These include stellar flares, where stars suddenly release magnetic energy; and neutron star mergers, where two dense stars collide together.

But one class of explosions outshines the rest: gamma ray bursts are the most energetic explosions seen in the universe.

No gamma ray bursts have been documented in our galaxy yet, which may not be a bad thing.

A gamma ray burst pointed directly at the Earth would probably lead to a mass extinction event, and the end of civilisation as we know it.

Undocumented events may in fact already have caused mass extinction events in Earth's history.

Gamma ray bursts have been seen far away, however.

The paper suggesting researchers had discovered a new gamma ray burst in the most distant known galaxy was published in 2020.

Using the Keck telescope on Mauna Kea, Hawaii, the researchers observed strips of the sky, and happened to see a bright flash, just a few seconds long, in one of their exposures.

By modeling the duration and brightness of the flash, they ruled out the possibility that it was a natural or human-made satellite close to home.

They also ruled out a number of other astronomical explanations, and concluded that the most likely explanation was, indeed, a gamma ray burst.

The Roman Baranowski Telescope/Poznań Spectroscopic Telescope used to confirm the man-made nature of the flash, and the position of GN-z11.

Hubble Team Breaks Cosmic Distance Record

This animation shows the location of galaxy GN-z11, which is the farthest galaxy ever seen.

The video begins by locating the Big Dipper, then showing the constellation Ursa Major.

It then zooms into the GOODS North field of galaxies, and ends with a Hubble image of the young galaxy.

GN-z11 is shown as it existed 13.4 billion years in the past, just 400 million years after the big bang, when the universe was only three percent of its present age.

Wow. That last video... put me into a trance

Justbtrying to imagine that... 13.4 billion years

And here we are.. in comparison, we are just saplings
