When the Betelgeuse star will explode?

(ORDO NEWS) — According to the conclusions of astronomers, the red giant is much closer to us than previously thought. Betelgeuse’s transformation into a supernova may occur in 100 thousand years. Then there will be a huge explosion.

The study was conducted by Dr. Meredith Joyce of the Australian National University. The specialist was able to more accurately figure out the distance from the star to the Earth, the size of Betelgeuse, as well as the estimated lifetime.

The red supergiant has long attracted specialists, and recently made it draw attention again when it lowered its brightness. It is worth noting that Betelgeuse is considered one of the brightest stars in the sky, but astronomers have been observing a dimming for two years in a row.

Scientists have made conclusions about a possible explosion of the star in the near future. If the first eclipse was associated with the arisen dust cloud, then the second – with the pulsation of the object itself.

To understand the physical processes that govern the star, experts have resorted to hydrodynamic and seismic simulations. Study co-author Shing-Chi Leung from the University of Tokyo noted that the pulsation of the star caused the wave pressure, which was sound waves.

In the core of Betelgeuse, a thermal reaction of helium is currently taking place. There is still a lot of time left before the explosion – about 100 thousand years. The star is 530 light years away. This is 25% closer than scientists previously thought. The distance is sufficient so that in the event of an explosion, the Earth is not in danger.
