🆕 Long Duration Gamma Ray Burst (GRB 211211A) - Origin❓

Long Duration Gamma Ray Burst GBR 211211A with peculiar Origin.

Deep-space discovery: Oddball gamma-ray burst forces revision of theoretical framework.
Bizarre long gamma-ray burst came from merging stellar corpses.

On Dec.11, 2021, a GRB triggered several gamma-ray detectors in space, including NASA's Fermi Gamma-ray Telescope and the Neil Gehrels Swift Observatory. This burst, with a duration of nearly 70 seconds, would typically be regarded as a normal long GRB. That is, until multiple teams from the U.S. and Europe performed follow-up observations and discovered a surprising signature.

"This GRB includes two parts: a 13-second long hard spike and a 55-second softer extended emission," said UNLV alumnus and study corresponding author Bin-Bin Zhang, who's currently with China's Nanjing University. "The duration of the 13-second hard spike should have completely excluded this burst from the short GRB category."

Scientists traced a high-energy blast of radiation - called a gamma-ray burst - to the merger of two neutron stars and an explosion called a kilanova that resulted from the cosmic collision. 

The gamma-ray burst (GRB) could change our understanding of the universe's most powerful explosions and upend decades of thinking about them. It was previously believed that GRBs only resulted from the destruction of massive stars, but astronomers now believe that some can result from the combination of two neutron stars.

💡Key Points:
2. Scientists detected a gamma-ray burst that changes their understanding of how these cosmic explosions happen
3. It was believed that GRBs only resulted from the destruction of huge stars, but astronomers now believe that some result from combining two neutron stars
4. They found evidence of a kilanova - a rare event that happens after the merger of a neutron star with either another star or a black hole 
5. 'This event represents an exciting paradigm shift for gamma-ray-burst astronomy,' Jillian Rastinejad, who led the research

Providing sources and everything . What a channel simply great keep it up

Sir kya ye possible hai ki ek Black hole to doosre black hole ko hin apne andar sametle, this based on their Mass.

Agr kilo Nova bana, to definitely dead star (black hole) se to nahi bana hoga, to ho sakta hai ki woh, Normal Neutron star se bana ho yani ki woh SMALL GRB ho, lekin as apne bola ki, LGRB 2 second se kuch mins Tak hota, yani ke ek naya hi discovery hai???
