Bottom line: Rigel, the brightest star in the constellation Orion the Hunter, shines a brilliant bluish-white color. It's much hotter and more massive than our sun, and someday, Rigel will explode as a supernova.Jan 19, 2022

Is Rigel going to explode?

Other stars relatively close to us that could go supernova include Deneb, Rigel and Spica, the latter two visually close to Betelgeuse in the night sky. Research also suggests that a star called V Sagittae, 7,800 light years distant in the tiny constellation of Sagitta, could explode around the year 2083.

What stars will explode in 2022?

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. And the mechanism behind it is fascinating as well. This story really begins 10 years ago, when astronomers closely monitored a distant star in Scorpius.

What will happen when Rigel dies?

Rigel's large mass (18 times that of the sun) will mean Rigel will become a black hole. When the star runs out of fuel, it can no longer push gravity back, and the core will collapse. After the core collapses on itself, gravity, pushing against the star, will compact the core until it is very small.

Will the sun explode in 2022?

Luckily for us here on Earth, the eruption on February 15, 2022 occurred on the farside of the sun, the side facing away from our planet. But ESA and NASA predict geomagnetic storms are possible in the next few days as the active region on the sun responsible for the blast turns toward us.

Is Betelgeuse going supernova?

Betelgeuse is a red supergiant — a type of star that's more massive and thousands of times shorter-lived than the Sun — and it is expected to end its life in a spectacular supernova explosion sometime in the next 100,000 years.

What if Betelgeuse exploded?

If we were too close to Betelgeuse when it explodes, our atmosphere and cells would be fried by the radiation and gamma waves. When you're exposed to high doses of radiation, it can burn and scar your skin, cause genetic mutations, and can ultimately be lethal. Gamma radiation, in particular, is incredibly powerful.

Will the supernova in 2022 destroy Earth?

According to NASA, a supernova would have to be within 50 light-years of Earth before we would feel its damaging effects. The 2022 lunar calendars are here.

Will there be a supernova soon?

Supernovae explode and fade away over time. Researchers predict that a rerun of the same supernova will make an appearance in 2037.

Will Rigel become a black hole?

With an estimated age of seven to nine million years, Rigel has exhausted its core hydrogen fuel, expanded, and cooled to become a supergiant. It is expected to end its life as a type II supernova, leaving a neutron star or a black hole as a final remnant, depending on the initial mass of the star.
