The world of astronomy is still surprising with significant findings, and one of them has just been detected by NASA's NICER telescope, located at the International Space Station.

A NASA telescope captures an unusual burst of X-rays in space.

It is one of the brightest X-ray explosions captured so far, from a pulsar at 11,000 light-years in the constellation Sagittarius.

According to a statement from NASA, this phenomenon revealed many phenomena that have never been seen together in a single explosion, in addition to the subsequent fireball briefly lit for reasons that astronomers still cannot explain.

As the US space agency reveals, the explosion released as much energy in 20 seconds as our Sun does in almost ten days.

This explosion was outstanding. We see a two-step change in brightness, which we believe was caused by the expulsion of separate layers of the surface of the pulsar, and other features that will help us decode the physics of these critical events.

The fireball continued to develop for another two seconds and then peaked, expelling the most massive helium layer. The helium expanded faster, exceeded the hydrogen layer before it could dissipate, and then slowed down, stopped, and settled back on the surface of the pulsar.

The pulsar briefly brightened again at approximately 20 percent for reasons that the team does not yet understand.

The detail that the NICER telescope captured in this record eruption will help astronomers sharpen their understanding of the physical processes that drive thermonuclear outbreaks and other explosive pulsars, the statement said.
