An explosion of a nearby star might leave Earth and its surface and ocean life relatively intact. But any relatively nearby explosion would still shower us with gamma rays and other high-energy radiation. This radiation could cause mutations in earthly life.
A supernova combined with a boosting magnetic field could have a further reach than normal. But even with an ideal magnetic field, there are no stars anywhere close to us that could pose a risk. You’re safe from deadly supernova radiation. Just don’t think about gamma ray bursts.
Theoretically, though, if a star were to go supernova one light year away from Earth it would rip our planet and the entire solar system to shreds. The force of the shockwaves would easily destroy every nearby celestial object, and leave our solar system as a nebula remnant that would eventually lead to the formation of new stars and planets.
But how far is “near?” New research suggests it’s a lot farther than scientists previously believed. A previous study found that any supernova that went off within about 25 light-years would be enough to wipe us out, but any farther than that and we’d be mostly safe.
Can supernova kill you?

What would happen if a supernova hit us?
Both types are extremely powerful, sending energetic radiation and blast waves of ejected gas far into space. If a supernova explosion were to occur within about 25 light-years of Earth, our planet would probably lose its atmosphere, and all life would perish.
Can you survive a supernova?
Can life survive? There is no way for life to survive on the surface of a planet witnessing a supernova. As shown above, a habitable planet orbiting Betelgeuse will lose at least 4 km of its surface, vaporized to space.
Can a supernova destroy life on Earth?
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.
Will we see a supernova in 2022?
While scientists are confident a supernova will occur in 2022, whether it occurs in our galaxy is a different matter. In any given year, it is an unlikely prospect. On the other hand, one day it may just happen in our galactic neighbourhood. If it does, astronomers say they will be ready.
Can a supernova kill us?

Will the next supernova destroy Earth?
Although they would produce a substantial sight, were these “predictable” supernovae to occur, they are thought to have little potential to affect Earth. It is estimated that a Type II supernova closer than eight parsecs (26 light-years) would destroy more than half of the Earth’s ozone layer.
Will there be a red Nova in 2022?
While scientists are confident a supernova will occur in 2022, whether it occurs in our galaxy is a different matter. In any given year, it is an unlikely prospect. On the other hand, one day it may just happen in our galactic neighbourhood. If it does, astronomers say they will be ready.
Will the supernova in 2022 happen?
In 2022—only a few years from now—an odd type of exploding star called a red nova will appear in our skies in 2022. This will be the first naked eye nova in decades. And the mechanism behind it is fascinating as well.
Will 2022 have a supernova?
While scientists are confident a supernova will occur in 2022, whether it occurs in our galaxy is a different matter. In any given year, it is an unlikely prospect. On the other hand, one day it may just happen in our galactic neighbourhood. If it does, astronomers say they will be ready.
Will 2 stars collide in 2022?
According to study from a team of researchers from Calvin College in Grand Rapids, Michigan, a binary star system that will likely merge and explode in 2022. This is an historic find, since it will allow astronomers to witness a stellar merger and explosion for the first time in history.
Will I see a supernova in my lifetime?
Unfortunately, supernovae visible to the naked eye are rare. One occurs in our galaxy every few hundred years, so there is no guarantee you will ever see one in our galaxy in your lifetime.

Dark energy’s weakness may be why supernovae didn’t kill us all
Massive stars, which live short lives and then explode as incendiary supernovae, would deliver lethal doses of radiation to nearby planets, sterilizing any life that happened to exist—and leaving behind no observers.

Yes, there are very real stars– as in “great balls of nuclear fire a million miles across” — with a velocity so great that they can actually escape the gravitational pull of their galaxies and roam free throughout the universe.
