Astronomers say they've put to bed the mystery of why one of the most familiar stars in the night sky suddenly dimmed just over a year ago.Betelgeuse, a red supergiant in the constellation of Orion, abruptly darkened in late 2019, early 2020.The behaviour led many to speculate that it might be about to explode.But a team using the Very Large Telescope (VLT) in Chile say the cause was almost certainly a giant dust cloud between us and the star....
how much of a electromagnetic disturbance would that star cause?
