Betelgeuse dims 70% ahead of a potential supernova

June 30, 2020

There has been much speculation a super giant star could be about to explode  creating a real life super nova…for the red giant stars like the Betelgeuse.

But expectations and rumours cooled recently with cold patches on the very bright star which is quite close to Earth  -  thought to be the reason  why it suddenly dimmed down at the back end of last year.

An international team of astronomers, led by Dr Thavisha Dharmawardena from the Max Planck Institute for Astronomy, have demonstrated that the dimming was most probably caused by giant star spots covering up to 70% of Betelgeuse's surface

.Betelgeuse is about 500 light-years from Earth and as much as it may well be reaching the end of their sparkle, nobody know when it will explode and some say that could take as long as hundreds of thousands of years or even as much as a million years for the lights to go out completely.
