Astronomy enthusiasts should all know.
The so-called supernova explosion.
Refers to a kind of violent explosion certain stars undergo when they approach the end of their evolution.
Such explosions are extremely bright, and the sudden electromagnetic radiation during the process often illuminates the entire galaxy it resides in.
It can last for weeks to months before gradually fading into invisibility.
During this period.
A supernova radiates an amount of energy comparable to the total energy radiated by the Sun throughout its entire life.
On the other hand.
While supernova explosions in the universe are a dazzling phenomenon, magnificent, and enchanting.
For humanity, it actually poses a certain risk.
During the explosion, a supernova releases a large amount of gamma rays, which radiate at light speed to the Earth's atmosphere.
Gamma rays induce a special chemical reaction when they interact with the atmosphere:
They convert nitrogen molecules into nitrogen oxides.
