What is a Supernova?
A star with a mass 8 to 25 times the mass of the sun will eventually collapse due to gravitational collapse, eventually leaving a neutron star. Studies have shown that if they are more massive stars, they will end their lives by forming black holes. This black hole-forming eruption is the largest supernova eruption in the universe, called a "hypernova" (hypernova), or a "supernova". Supernovas are extremely powerful, they can destroy all life instantly, and stars are severely damaged as a result.
Super supernova
- Black holes form inside stars, leading to star destruction
- There is still a lot of uncertainty about this supernova, and it is still being researched. Extreme supernova is more than mass
- Can only inhale substances
- There is another situation, in
- According to theoretical analysis, a star with a mass of more than 140 times the mass of the sun is very unstable, and will eventually burst, leaving nothing behind. In 2010, scientists were
- It is believed that if an extremely supernova explodes near Earth, its high-energy radiation will definitely destroy Earth's life. According to a joint study conducted by scientists from NASA and the University of Kansas in 2005, it is pointed out that the Ordovician-Silurian extinction event of 450 million years ago may have been a supernova release. Caused by a gamma-ray burst, the process lasted ten seconds and destroyed half of the earth's ozone layer, causing the ultraviolet rays emitted by the sun to hit the earth, causing a large number of organisms on the ground and near the sea to die, thereby destroying the food chain.
- If a supernova occurs only on a star that is 40 times more massive than the Sun, then Earth will be safe and spared. The closest possible supernovae to the Earth is the Haishan II (ship ) star, which is 7,500 light-years away from Earth and 140 times the mass of the Sun.
