Astronomers think some of these explosions occur when a massive star — five or 10 times the mass of our sun — detonates, abruptly becoming a black hole. Gamma-ray bursts may also occur when two superdense stellar corpses called neutron stars collide, often forming a black hole. And conveniently, a gamma-ray burst that scientists watched during a few nights in 2019 likely occurred only about 1 billion light-years away from Earth, relatively close by for these dramatic events.
Two NASA space-based observatories, Fermi and Swift, first detected the event, which is known as GRB 190829A because it was detected on Aug. 29, 2019. The fireworks came from the direction of the constellation Eridanus, a large swath of sky in the Southern Hemisphere.
When the scientists behind the new research heard about the gamma-ray burst detection, they mobilized a set of five gamma-ray telescopes in Namibia, called the High Energy Stereoscopic System (HESS). Over three nights, the telescopes observed the explosion for a total of 13 hours, in an attempt to understand what took place.
With those observations, the scientists could analyze much higher-energy photons than is possible in more distant gamma-ray bursts.
During those analyses, the team noticed that the patterns of X-rays and very high-energy gamma-rays matched — something scientists wouldn't expect, since they believe different phenomena cause the two different types of radiation.
But so far, scientists have only observed four of these bright explosions from the surface of Earth, so they're hoping that new instruments and additional observations give them more insight into the details of gamma-ray bursts.

Our alien overlords that the powers that be have been preparing us for with their talk of UFOs?
Too far away for that, I think.
Well, I’m sure they would have some sort of warp/hyperspace drive. (or Dean Drive.)
Gamma rays? Have we consulted Dr. Banner?
Understood, but even if that were the case I would expect them to “drop out of warp” a lot closer. Maybe somewhere just outside the heliosphere?
Blame global warming. It works for everything else.
Infinite Improbability Drive is faster
Gamma Day Bursters were discovered by probes designed to detect nuclear explosions on Earth. Since the blast is usually only seconds long it’s been a long search trying to establish the cause of these mysterious events. They thought they had the answer but the Universe still has more surprises for them.
“Too far away’
Might be the turbo kicking in.

We’re all gonna DIE. These f#%^ing things cause climate change. And sea level rise. And volcanoes.
Guvmint needs to spend another $6 Trillion dollars
