Can the earth survive a supernova?

Absolutely. Any planet with life on it near a star that goes supernova would suffer. X- and gamma-ray radiation from the supernova could damage the planet’s ozone layer (assuming it had one), exposing its inhabitants to harmful ultraviolet light from its parent star.

What if Betelgeuse exploded?

Whenever Betelgeuse does blow up, our planet Earth is too far away for this explosion to harm, much less destroy, life on Earth. Astrophysicists say we’d have to be within 50 light-years of a supernova for it to harm us. Betelgeuse is nearly 10 times this distance.

Why do the sun or stars go supernova?

One type of supernova is caused by the “last hurrah” of a dying massive star . This happens when a star at least five times the mass of our sun goes out with a fantastic bang! Massive stars burn huge amounts of nuclear fuel at their cores, or centers. This produces tons of energy, so the center gets very hot.

Will the Sun explode into a supernova?

Our sun will never explode in a supernova. Only massive stars with initial mases larger than 10 solar masses will eventually evolve to a supernova. This is not the case for our sun.

Is a supernova brighter than the Sun?

‘Assassin’ supernova discovered that is 570bn times brighter than sun. Super luminous supernovas — extra bright stellar explosions — are believed to be rare. The newly discovered supernova is especially rare: It is more than twice as luminous as any supernova observed to date, including the previous record-holders.

What would happen if Earth went supernova?

Produced in the core of a supernova and carrying away 99\% of its energy, all life on an Earth-like would receive a lethal dose of neutrinos within 1/20th of a second as every other location on the planet. No amount of shielding, even from being on the opposite side of the planet from the supernova, would help at all.
