Question

If the Betelgeuse explodes today, who will be able to observe it? People
living in the year

Answer 1

Answer:

• It would take around a year for people to be able to witness the supernova in the daytime sky. And as the supernova remnant dims, it would be visible to the human eye at night for several years.
• If we were too close to the explosion of Betelgeuse, the radiation and gamma waves would fry our atmosphere and cells. High radiation doses can burn and harm your skin, change the makeup of your genes, and even be lethal if they are sustained. Gamma radiation in particular is very powerful.
• Since Betelgeuse is located 650 light years away from Earth, it takes 650 years for light to reach us. If the explosion took place in the year 3000 AD, then the light would appear 650 years later, in the year 3650 AD.
