Jan 01, 2020 · If Betelgeuse does go supernova, is there any danger to us here on Earth? The simple answer is no. The star is about 700 light-years away , which would attenuate the impact of the blast. Ancient astronomers would have easily spotted Betelgeuse because of its size and relatively close distance from Earth: it is about 600 light-years away and has a variable brightness generally peaking at 0.4 and falling below 1.2. 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 ... Rso shelf lifeAnd it's only 642.5 light-years from Earth, much closer than Vela. "We can hope that's not what's about to happen because Betelgeuse is really close," he said. Journal Reference: G. Robert Brakenridge. Solar system exposure to supernova γ radiation. International Journal of Astrobiology, 2020; 1 DOI: 10.1017/S1473550420000348 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. As seen from Earth, Betelgeuse as a type IIP supernova would have a peak apparent magnitude somewhere in the range −8 to −12. This would be easily visible in daylight, with a possible brightness up to a significant fraction of the full moon, though likely not exceeding it. This type of supernova would remain at roughly constant brightness ...

  • Betelgeuse, which is located approximately 640 light-years from Earth in the constellation Orion — is one of the biggest and brightest stars in our galactic neighborhood. It could swallow the Sun... NASA and astronomers worldwide have been watching Beletgeuse for some time because it has been growing (if it were placed in the center of our solar system, its outer edge would reach Jupiter) and appears to be heading towards supernova. That would be a thrill for astronomers – it’s only 725 light years away – but it would potentially create the closest black hole to Earth.
  • Will the explosion of Betelgeuse destroy earthly life? When 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. So we’re safe from Betelgeuse.
  • However, Betelgeuse would outshine Kepler’s Star. Mr Brown wrote in an article for The Conversation: “If [Betelgeuse supernova] did occur, it would become the brightest supernova ever observed. “In a matter of days, it would become as bright as the full moon, be visible during day time and be bright enough at night to cast shadows on Earth.

Jan 14, 2016 · The supernova would hang as a blinding point in our sky, like a smaller, but much more dangerous Sun. Dangerous because in addition to the visible light, the exploded star would pour X-rays, gamma ...
  • Anyway, Betelgeuse is around 640 lightyears or 200 parsecs away. The mean absolute magnitude of a Type II supernova is -16.45 . Figuring out the apparent magnitude of an object of known absolute magnitude at a known distance (in parsecs) is pretty easy: m-M=5*log(D) - 5. so m+16.45=5*log(200)-5. and m = -9.95 (or thereabouts.) Let's go with -10. Betelgeuse Supernova watch - we’ll know by Feb 21st Feb 21st is the day we’ll know if the puzzling dimming of Betelgeuse is just an alignment of dimming cycles in a highly variable star, or a prelude to a supernova we’ll be able to witness with our bare eyes.

In fact, if it was placed where our Sun is that it would reach as far as Jupiter, engulfing Mercury, Venus, Earth and Mars. Now, when we think about the most fantastic and terrifying explosions in the universe you might hear or think of supernova.
  • Betelgeuse, which is located some 725 light-years from Earth, began dimming radically in October 2019, dropping about two-thirds of its brilliance. This led some astronomers to speculate that the red supergiant – 1000 times the magnitude of the Sun – may be getting close to finishing its life in a supernova explosion. Betelgeuse to go Supernova in Days or Decades? #21886605 BY Aaron747 - Sat Dec 28, 2019 1:00 am The shoulder of Orion is fading fast, according to astronomers. One of the most well-known stars in our stellar neighborhood may be dying, is about to, or its life-ending event could still be decades or centuries away.
  • However, the researchers estimated this is still plenty of distance between the star and Earth to protect our planet from sustaining significant impacts when the star eventually explodes. So when will Betelgeuse experience a supernova? It may not happen for another 100,000 years, according to the researchers. Radiation from the Betelgeuse supernova will certainly have some measurable effects on Earth's environment, but probably only a minor impact on life. Betelgeuse is too far away to significantly...Astrophysicist Miguel Montargès has a clear memory of the moment the stars became real places to him. He was 7 or 8 years old, looking up from the garden of his parents’ apartment in the south of France. A huge, red star winked in the night.
