•Could a supernova ever destroy Earth?

When Betelgeuse explodes, it will be brighter than any planet and almost as bright as the full moon.
Most of the energy emitted by a supernova is in the form of neutrinos, ghostly particles that hardly ever interact with matter.
But the good news is, supernovas tend not to produce copious amounts of high-energy radiation.
There are no known supernova candidates within 30 light-years of Earth .
Type Ia supernovas are triggered when white dwarfs accumulate material from an orbiting companion.
Gamma-ray bursts are much more dangerous because they are incredibly powerful and their explosive energies are focused into narrow beams that can punch over 10,000 light-years through a galaxy.
Thankfully, the nearest candidate is the binary white dwarf IK Pegasi , which sits safely about 150 light years away.
