The Crab Nebula is the leftover, or remnant, of a massive star in our Milky Way that died 6,500 light-years away. The core collapses, and a supernova is born. evidence on Earth of a supernova type Ia explosion, . A massive star that exploded near Earth about 2.5 million years ago—a supernova—may have helped drive the megalodon to extinction and may even have affected human evolution.

Our sun is a giant sphere of unimaginably hot hydrogen and helium located around 93 million miles from Earth. There are a lot of negative effects of supernova explosion on both organic and non-organic matter on earth but the probability of it occurring inside 500 light-year radius from the earth is very low. Could a supernova destroy Earth? - How It Works The fourth appearance of the flare is expected to be visible in . A supernova (/ ˌ s uː p ər ˈ n oʊ v ə /; pl. The density of the star creates a massive gravitational pocket and pulls everything within its vicinity into it. Scientists take temp of atoms in supernova shock wave - Futurity The explosion will be visible from Earth with the naked eye, and it could be about as bright as Polaris, the north star. The supernova is indicated by an arrow in the upper left inset. Molnar predicts that the stars will merge and create an explosion in 2022, "give or take a year," according to the statement. .
