An explosion of a nearby star might leave Earth and its surface and ocean life relatively intact. But any relatively nearby explosion would still shower us with gamma rays and other high-energy radiation. This radiation could cause mutations in earthly life.21-Dec-2021

Will the supernova in 2022 destroy Earth?

Will the supernova in 2022 destroy Earth? It is estimated that a Type II supernova closer than eight parsecs (26 light-years) would destroy more than half of the Earth's ozone layer.

Will we see a supernova in 2022?

This is exciting space news and worth sharing with more sky watch enthusiasts. In 2022—only a few years from now—an odd type of exploding star called a red nova will appear in our skies in 2022. This will be the first naked eye nova in decades.

What if the sun exploded?

For Earth to be completely safe from a supernova, we'd need to be at least 50 to 100 light-years away! But the good news is that, if the Sun were to explode tomorrow, the resulting shockwave wouldn't be strong enough to destroy the whole Earth. Only the side facing the Sun would boil away instantly.

Can a supernova create a black hole?

Stellar-mass black holes are born with a bang. They form when a very massive star (at least 25 times heavier than our Sun) runs out of nuclear fuel. The star then explodes as a supernova.

Could the sun explode at any time?

Scientists have conducted a lot of researches and study to estimate that the Sun is not going to explode for another 5 to 7 billion years. When the Sun does cease to exist, it will first expand in size and use up all the hydrogen present at its core, and then eventually shrink down and become a dying star.

Will I see a supernova in my lifetime?

Unfortunately, supernovae visible to the naked eye are rare. One occurs in our galaxy every few hundred years, so there is no guarantee you will ever see one in our galaxy in your lifetime. In 1987, a supernova called 1987A was visible in a nearby galaxy called the Large Magellanic Cloud.

What if the Sun died?

After the Sun exhausts the hydrogen in its core, it will balloon into a red giant, consuming Venus and Mercury. Earth will become a scorched, lifeless rock — stripped of its atmosphere, its oceans boiled off. Astronomers aren't sure exactly how close the Sun's outer atmosphere will come to Earth.

What would happen if there was no moon?

The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.

How is a black hole born?

In the stellar remnants of a supernova, however, there are no longer forces to oppose that gravity, so the star core begins to collapse in on itself. If its mass collapses into an infinitely small point, a black hole is born.
