What will happen to us when Betelgeuse explodes?

Whenever 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.

What will Betelgeuse leave behind when it dies?

As that star died and became a black hole, it gently cast off its outer envelope and grew five times brighter. If Betelgeuse follows suit, its brightness will increase but never surpass that of Sirius, the brightest star in the night. Then Betelgeuse will disappear, leaving a literal hole in Orion.

When Betelgeuse explodes Will it become a black hole?

If the remains are less than 2-3 solar masses in the central region, then Betelgeuse will become a neutron star and will appear as a pulsar, as seen from the earth. If the explosion remains are more than 3 solar masses in the central region, a black hole formation is possible.

Will Betelgeuse become a neutron star or a black hole?

If Betelgeuse does explode, it could become either a neutron star or a black hole. To become a black hole, the material left over by the supernova explosion would have to equal more than 3 solar masses.

Can we see Betelgeuse from Earth?

You can see Betelgeuse with the naked eye. Betelgeuse’s colour is due to the fact that it is an ageing ‘red supergiant’ star, over one billion kilometres in diameter (that’s nearly 1,000 times the size of our Sun).

Will Betelgeuse become a white dwarf?

In fact, Betelgeuse is one of the largest stars we know: but it’s also nearing the end of its life. Then, the star’s core continues to collapse until it becomes a white dwarf. This process will eventually happen to Betelgeuse when it runs out of fuel and implodes under its own weight.

Is Betelgeuse a massive star?

Betelgeuse is just one of the many aging, massive stars — called red supergiants — that could go supernova at any moment. But as one of the closest and brightest, Betelgeuse is the one that space enthusiasts know best.

Can the human race survive a population explosion?

Will the human race go extinct within 100 years?

Could a single nuclear bomb wipe out a civilization?

A single nuclear bomb hitting a large city would certainly wipe out an unthinkable number of people, but it probably wouldn’t end civilization. However, it’s the retaliation of another nuclear bomb that could do us all in.

Is climate change to blame for the human race’s imminent demise?

Fenner blames the onset of climate change for the human race’s imminent demise. He said: ‘We’ll undergo the same fate as the people on Easter Island.
