(ORDO NEWS) — Betelgeuse is the closest red supergiant star to Earth and is predicted to explode soon. However, recent observations show that she is not going to give up yet.
The star, which is in the final stages of its existence, partially exploded in 2019. Surprisingly, the Hubble telescope captured her recovery.
Betelgeuse is the closest red supergiant star to Earth, and when it suddenly began to dim in 2019, it caught the world’s attention. This will be the first time we can see a star collapse and explode.
Astronomers have now confirmed that the bright red supergiant star did explode in 2019, losing much of its visible surface and causing a giant surface mass ejection (GSM).
Betelgeuse ejected 400 billion times more mass than a normal ejection on the Sun. Now she is slowly recovering from this catastrophic injury.
“Betelgeuse is doing some very strange things right now. The inside is kind of bouncing,” said Andrea Dupree, an astrophysicist at the Harvard Center for Astrophysics and the Smithsonian Institution in Cambridge.
Astronomers used the Hubble telescope and several other observatories to observe the star. Observations have shown how red stars lose mass at the end of their lives when their fusion furnaces burn out and then explode as a supernova.
NASA has stated that the amount of mass loss significantly affects their fate. However, Betelgeuse’s surprisingly capricious behavior does not prove that the star is about to explode anytime soon.
“We have never seen a huge mass ejection from the surface of a star before.
There is something we don’t fully understand. This is a completely new phenomenon that we can observe directly and determine the details of the surface using Hubble.
We are watching the evolution of stars in real time,” added Andrea Dupree.
What happened in 2019?
Telescopes aimed at Betelgeuse in 2019 found that the star was suddenly dimming, in what was initially thought to be the beginning of its end.
However, further analysis showed that the unexpected dimming was caused by a huge amount of hot material ejected into space. The resulting dust cloud covered the light of the star.
Betelgeuse is easy to find on the right shoulder of the constellation Orion, making it visible even with ordinary telescopes used by amateur astronomers.
Now the star is so large that, if it were to replace the Sun, its outer surface would go beyond the orbit of Jupiter.
