  • Jan 05, 2020 · Betelgeuse, one of the brightest stars in the night sky, has been dramatically dimming recently, indicating that it's about to enter its last phase of life before finally exploding into a supernova. Some scientists believe that Betelgeuse may be ready to go supernova anytime between now and 100 000 years from now, making it as bright as the moon, or even brighter, for weeks
  • Dec 26, 2019 · There have been attempts to link past supernova events with extinctions. These are based on correlating isotope bands with geological events. The jury is still out. Even if Betelgeuse does pose a hazard to life on Earth, it will not affect us until 100,000 years after it goes nova. That’s 20x the span of human history.
  • Although Betelgeuse is only around six million years old, some regard the star's current variability as suggesting that it is already in the carbon burning phase of its life cycle, and will therefore undergo a supernova explosion at somme time in the next thousand years or so. Skeptics dispute this contention and regard the star as being likely to survive much longer.
  • A near-Earth supernova is a supernova close enough to the Earth to have noticeable effects on its biosphere. This would need to be nearer than about 100 to 3000 light-years away, depending upon type and energy - different figures have been suggested.
  • From Earth, its visual magnitude (or appearant magnitude) is 0.58 (0.3 to 1.2) according to Wiki. So if you plug -5.14 into M (absolute magnitude) and 600 LY into d (distance) you get its visual (appearant) magnitude from Earth of 1.8, which is at the high end of the range wiki gives. Change 600 LY into 4.5 LY and you get -9.4.

  • Although it’s far enough away to keep Earth safe from radiation when it goes supernova, red supergiant star Betelgeuse is about 700 times the size of our sun, with a radius roughly equivalent to the orbit of Jupiter. “It would be astounding,” said Andy Howell, an astronomer at the Las Cumbres Observatory and the University of California at Santa Barbara about Betelgeuse’s inevitable explosion.

  • Jan 03, 2020 · If the star does become a supernova, Betelgeuse would likely be as bright as, or even brighter than the moon for weeks or even more. At 642.5 light-years from Earth, it would be the closest supernova observed and recorded by humans (closer than the Crab Nebula, which is 6,523 light-years from Earth and is the result of a supernova reported to have taken place in A.D.1054).

  • Jan 05, 2020 · Betelgeuse is 8 million-plus years old but may still be thousands of years away from its end. There is another problem. That light years separate earth and Betelgeuse? Yes. It is 640 light years away. So it will take 640 years for light from Betelgeuse to reach us. That means, even if the supernova happens, we won’t know in a hurry.
