As early as the end of 2019, , The red supergiant star that forms the shoulders of Orion, suddenly began to dim. Initially, some astronomers believed that the star was dying and was about to explode into a supernova, but this is not the case. On the contrary, Betelgeuse returned to normal brightness.
Published in a new paper , Scientists say that the “great dimming” of Betelgeuse is partly caused by bubbles ejected by stars.use (VLT) In Chile, Miguel Montargès from the Paris Observatory in France and his team analyzed images of red supergiant stars.
Emily Cannon, one of the co-authors of the study, said: “Our general idea is that there is a cold spot on the star, and the local temperature drop causes the previously ejected gas to condense into dust.” “So, cold spots on the surface will initially make us look darker. But this kind of dust condensation will increase the rapid decline in star brightness.”
Unfortunately, for those who wish to see a supernova at some point in their lives, this event is not considered a sign that Betelgeuse is about to end his life. In cosmic terms, it may be decades, even hundreds, or thousands of years later.
