How likely is a gamma ray burst
WebGamma-ray bursts and supernovae happen when very massive stars explode at the end of their lives. The stars that make supernovae are probably at least 8 times the mass of the sun, the stars that make gamma-ray bursts are probably even more massive. Probably 20-40 times as massive as the sun. WebAn explosive gamma-ray burst, one of the brightest ever detected, lit up in the sky on 9 October 2024. A gamma-ray burst is a super energetic explosion and this one originated in the constellation Sagitta. The signal of the burst – called GRB 221009A – was picked up by many ESA observatories.

WebCould the Earth survive a gamma ray burst if that burst occurred in our galaxy and the Earth is in the Sun's shadow?
