How fast is a supernova shockwave?
How fast is a supernova shockwave?
approximately 30,000 km/s
What remains after a supernova?
Neutron Stars The core that remains after a supernova explosion is an extremely dense ball of neutrons. If its mass does not exceed three solar masses it will remain a neutron star (Begelman & Rees, 43). Neutron stars besides being dense have intense magnetic fields.
Will a supernova happen in my lifetime?
Supernovae are not predictable in way, that suits human timescales. Betelgeuse is well known as a star at the end of its lifespan and its big enough to end in a supernova. But stars have a lifetime of a few billion years, so the best prediction we can make is, that Betelgeuse may have a couple of million of years left.
Will we see a supernova in 2022?
Molnar and his team determined that the stars would eventually collide, resulting in a kind of stellar explosion known as a “Red Nova”. Initially, they estimated this would take place between 2018 and 2020, but have since placed the date at 2022.
What are the odds of seeing a supernova?
approximately 20-50 percent
What star is supernova in 2022?
The period of the variations in KIC 9832227 has been observed to be growing shorter since 2013, leading to the prediction of the merger in 2022….KIC 9832227.

What would happen if 2 Suns collide?
While stellar collisions may occur very frequently in certain parts of the galaxy, the likelihood of a collision involving the Sun is very small. Astronomers say that if a stellar collision happens within 100 light years of the Earth, the resulting gamma-ray burst could possibly destroy all life on Earth.
What would life be like with two suns?
No sunscreen would prevent you from getting toasted by two suns. The Earth’s orbit could be stable if the planet rotated around the two stars. The stars would have to be close together, and the Earth’s orbit would be further away.
