•Could a supernova ever destroy Earth?
61% Informative
A supernova will be brighter than any planet and almost as bright as the full moon.
Betelgeuse is roughly 650 light-years away; it won't be a factor in damaging our planet.
The vast majority of the energy emitted by a supernova is in the form of neutrinos, ghostly particles that hardly ever interact with matter.
There are no known supernovas that tend to occur in our galaxy, but we're safe in that regard.
Type Ia supernovas are triggered when white dwarfs accumulate material from an orbiting companion.
Gamma-ray bursts are much more dangerous because they are more distant and difficult to predict.
Thankfully, the nearest candidate is the binary white dwarf IK Pegasi , which sits safely about 150 light-years away.
