…Research published in the journal Nature Astronomy shows how WOH G64, a giant binary star system in the Large Magellanic Cloud, has recently undergone a striking transformation…
…researchers say they’ve examined more than 30 years of brightness measurements and found that the star, long classified as a cold, red supergiant, has become markedly hotter – by over 1,000°C – and now appears yellow rather than red…
So, in 163 millennia, will the shockwave from this explosion reach Sol? Is this an existential threat for the distant future? I should hope by then whatever dominant species is on earth will have figured out how to hedge their bets and spread to multiple worlds.
This author claims the minimum safe distance from a supernova is about 160 light years.
WOH G64 is 160,000 light years away, so we’re probably fine.
163,000 light years from Earth.
This explosion is ancient history.
