Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe.
These energetic bursts are typically unleashed by the incendiary death of a star, or when it is shredded by a black hole.
The observation of repeating bursts has never occurred before, given that the events that produce them are so catastrophic, said Antonio Martin-Carrillo, an assistant professor in astrophysics at the University College Dublin in Ireland. But in July, several bursts were detected in a single day.
“(It’s) unlike any other seen in 50-years of GRB observations,” Martin-Carrillo said in a statement. He is the co-lead author of a study based on observations of the event published August 29 in [The Astrophysical Journal Letters](https://iopscience.iop.org/article/10.3847/2041-8213/adf8e1).
Do i understand it correctly that if one hits the Solar system – we are toast?
Can’t this be one and the same event that due to a gravitational lens effect (like an Einstein cross) arrived at different times on Earth?
It’s a pulsar, isn’t it? It’s always a pulsar
Dr. B. Banner is working closely with astronomers to find answers!
“50 years of GRB observations”……There might be similar every million years, we may have just got lucky. Until of course more are detected, a calculation can be estimated.
Witholding any speculations until the almighty Andromeda dude/dudette expands on this in the comment section
