Scientists working with NASA’s NuSTAR telescope have made a surprising discovery, observing the brightest cosmic explosion ever detected. The explosion, which occurred in a galaxy 390 million light-years away, was caused by a jet of energy unlike anything previously seen.

The team of scientists used NuSTAR to record the entire process of the explosion, which was more than 10 times brighter than any other gamma-ray burst ever observed.

The explosion was initially detected by NASA’s Swift satellite, which alerted astronomers that something unusual was happening. They then used NuSTAR to study the event in greater detail.

The explosion was caused by a massive star collapsing in on itself and forming a black hole. As matter from the star fell into the black hole, it released a jet of energy that traveled at nearly the speed of light. This jet of energy was responsible for the gamma-ray burst that scientists observed.

What makes this explosion so unusual is that the jet of energy was extremely focused, unlike other gamma-ray bursts, which are more diffuse. The team of scientists says this could be due to the magnetic field of the black hole, which may have played a role in shaping the jet of energy.

Overall, the discovery sheds new light on the process of black hole formation and the role that energy jets play in shaping the universe. Scientists hope to use these findings to better understand the most powerful forces in the cosmos.
