NASA suggests that the black hole monster may have committed a “magnetic coup”; all you need to know – Technology News, Firstpost

Perhaps the black hole overturned its magnetic field, causing a rare and mysterious explosion that was recorded by satellites. According to the National Aeronautics and Space Administration (NASA), the magnetic revolution took place in the galaxy 1ES 1927 + 654, 236 million light-years away.

A magnetic coup occurs when the South Pole becomes the North and vice versa.

A statement by scientists described this unusual celestial phenomenon. In March 2018, in visible light, the galaxy lit up almost 100 times, a few months after the eruption in 2017. The galaxy’s ultraviolet radiation increased 12 times, but further data showed that it actually decreased, indicating an unnoticed peak before. In June 2018, X-rays of the galaxy stopped.

Watch a NASA video that explains the events:

Emissions resumed in October of that year, indicating that a magnetic coup had taken place. By the summer of 2021, emissions have returned to baseline.

What does that mean?

The Milky Way and most other large galaxies have a supermassive black hole in the center that pulls matter. Matter first gathers into the accretion disk, surrounding the black hole. The matter is then heated, emitting visible, ultraviolet and X-ray light as it is pushed inward.

It forms a cloud of very hot particles (crown) when pushed inside. A new NASA study suggests that changes in the corona have led to the fact that X-rays coming from the heart of the galaxy 1ES 1927 + 654, temporarily stopped.

When a magnetic coup occurs, the field becomes weak and unable to support the crown, which can lead to the disappearance of X-rays. Later, the magnetic field is amplified in a new orientation

According to Sibashish Lakh, a research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the University of Maryland, “This event marks the first time we’ve seen X-rays completely fall out and other wavelengths fall.”

According to scientists, the magnetic field of a black hole creates and maintains the crown, so its X-ray properties can be affected by any changes in the magnetic field. This unprecedented event will help researchers better understand black holes.
