#astronomy #GammaRayBurst #supernova #GRB221009A
An article published in the journal "Nature Astronomy" reports a study on the gamma-ray burst cataloged as GRB221009A, the brightest ever detected, which confirms that it was caused by the collapse of a massive star, which subsequently exploded in a supernova.

More detail on Brightest of All Time – #gammarays
Beams from brightest #gammaray burst ever seen were pointed directly at #Earth
Boffins puzzle over #GRB221009A's shape unlike any other #astronomical electromagnetic jets, it is a strange structure #astronomers have never seen before. "It is 70x brighter than any other gamma-ray burst discovered in over 50yr of observation." Part of reason why e explosion is so bright is because beams were directly pointed at Earth

Interestingly, the ESA Gaia space observatory, located at the L2 Lagrange point similar to JWST, detected the GRB 221009A burst.
Gaia does not have a particle detector, but it routinely counts tracks created by charged particles on one its detectors, so that they can be excluded from the astrometric data.
On Oct 9, 2022, the unusual signal, shown in the graph below was measured, which was puzzling until news of the GRB came out!

Where is Gamma-Ray Burst GRB 221009A located in the night sky, as seen from Earth?
It is in the direction of the constellation Sagitta, close to the plane of the Milky Way (see skymap below).
Of course, it lies outside the Milky Way galaxy, 2.4 billion light-years away, while the Milky Way is only ~87,400 light years across.
Also, see graphic in previous post.

This insightful graphic shows the locations of the dust layers for the 5 smallest X-ray rings (inset, circled) from GRB 221009A. The thick line shows the direction to the GRB, and dark patches within it represent the dust layers that reflected the X-rays to create the ring image. The smallest ring corresponds to the most distant dust, located about 61,000 ly away and 4,600 ly above the galaxy's midplane.

Interestingly, GRB 221009A was first detected by the Voyager 1 spacecraft, now more than 23 billion km from Earth, about 19 hours before it was detected by more than a dozen satellites around earth built for astrophysics, planetary science, and solar observations.
Of course, data from Voyager 1 arrived after earth-based satellites sounded the alarm. Also, Voyager 1 is not along the line of sight to the GRB.

Comparison of gamma rays with other regions of the electromagnetic spectrum.
The wavelength of gamma rays is smaller than 0.00001 µm. Visible light wavelength is around 0.5 µm.
Gamma ray freq is > 30 exahertz, i.e., > 30,000,000,000 GHz.
From GRB 221009A, a large number of very high energy photons extending up to 18 TeV (2.8E-6 J) were detected, which corresponds to a freq. of 4.3E27 Hz.
