Isn't this just bonkers?
A massive gamma-ray burst went off in space recently and it was so strong, that it ionised the upper parts of Earth's atmosphere, changing how radio waves propagate through it. Detectors in India, Germany and UK observed this change 👇

Folks who work in these fields have mentioned that it is likely due to the collapse of a massive star, giving birth to a black hole, about 2 billion years ago.
Kinda blew my mind how it affects Earth's atmosphere so much!

Data (~10 hrs) from the orbiting Fermi Large Area Telescope shows gamma-ray light of the #GRB221009 event.

There are even some reports that amateur / ProAm astronomers have been able to catch the optical counterpart signal of #GRB221009 (not sure if these observations have been confirmed/vetted by astro community, at this stage though?)

Def. looking forward to reading the papers on this big event in the not too distant future!
oh lol, wait until you see what today's @apod is ... jinx!
whoa, adding this to this thread.
That remarkable Gamma-Ray Burst that happened ~2 billion years ago and hit our atmosphere, affecting radio signals, was imaged by @ESA_XMM and shows an echo of X-rays scattering off interstellar dust in marvellous rings
