Not only does it hold the entire solar system together with its gravity . Advertisement. This supernova was close to Earth at 20, 000 light-years away, it was so bright that it was visible in daylight. A coronal mass ejection (CME) is a vast cloud of electrically charged particles from the sun's upper atmosphere or corona that's heated to enormous temperatures and launched . An explosion very near to the solar system forming a supernova can annihilate the whole planet earth in this process. Supernova SN 2022blm in UGC 3457 galaxy: a image - 23 Feb. 2022.

Supernovas may have affected the Earth's climate in the last 40,000 years. That means, that even the normal solar flares will scorch the earth, and there will be electrical storms reaching the ground non-stop. Email.
