The largest cosmic explosion in history was recorded. Why do we care?

fireball “100 times larger than the solar system” Observed by astronomers, he went down in history as The largest cosmic explosion. Also known as starburst the Supernova.

according to Publishing From the related study in Monthly Notices of the Royal Astronomical Society It is believed that this event was caused by a huge cloud of gas – perhaps thousands of times more massive than the sun – that was swallowed by a supermassive black hole.

The bang (named AT2021lwx) is more than 10 times Brighter than anything known Supernova (See starburst).

It has lasted more than now Three yearsmaking it More powerful blast recorded at all.

The event was first discovered in 2020 by Zwicky Transit Facility in California, where it scans the night sky for sudden increases in brightness that could indicate cosmic events. like;

A supernova is passing by asteroids And comets.

“For a year this phenomenon went unnoticed. But gradually, it became brighter. Subsequent observations made it possible to calculate the distance, and then we realized that this is an unimaginable scale. pointed to guardian astronomer and chief of work, Dr. Philip Weisman.

“We calculated that it was an explosion 100 times the size of the solar system with a luminosity of about 2-3 times the luminosity of the Sun.

In three years, this event released about 100 times as much energy as the Sun has released in its 10 billion years of life.

Once we realized how very bright it was, we had to find a way to explain it.”.

It wasn’t in the reasonable range for a supernova, so his scenario was examined Tidal disturbance: when a star (or whatever) approaches Black holethe nearest side receives a larger side gravitational attraction From behind, the imbalance creates a strong tidal forcesthe star distorted And Dissolves.

Part of it is swallowed by the black hole. The other runs on a rotating disc.

In other words, this is what happens.

The simulations did not put the event observed by the researchers into this category, and thus tested the much larger gas cloud theory, such as “Supermassive black holes are usually surrounded by a huge halo of gas and dust. We speculate that some of this material may have been disrupted, perhaps by a galactic collision, and sent inwards.”.

These events, although very rare, can be so energetic that they are fundamental processes in how the centers of galaxies change over time. “.

Why do we care about all this?

If it is the phenomenon corresponding to what you have just read, then its eruption occurs especially near the Earth cosmic radiation It could have devastating consequences on a global scale.

Simulations showed that a pulse of energetic particles would dramatically alter the chemistry in the atmosphere, forming compounds such as Nitrogen dioxide that case acidification and attack it chemically Ozone Layer (which leads to higher levels of ultraviolet radiation from the sun reaching the earth’s surface).

Some of the energetic particles created during these reactions also reach the surface and thus can form Immediate radiation danger to life. The magnetic field will provide protection – reducing the impact of the cosmic ray blast on Earth.

Scientists assure that the chances of all this happening are very small.
