The Dimming of Betelgeuse Telescope Liv

The dimming was obvious to everyone when looking at the constellation Orion; it was very weird, Betelgeuse was almost missing. As a semi-regular variable star, this sort of thing is expected. The luminous red star in Orion's shoulder, Betelgeuse, has been dimming. Betelgeuse has long been one of the brightest stars in the sky, and it is likely over 8.5 million years old. The sudden dimming of the star has led some scientists to suggest that the star could be entering a pre-supernova phase before exploding spectacularly and collapsing in on itself Normally, the star dims and brightens over a cycle of about 420 days in a breath-like rhythm, rising and shrinking in measurement and luminosity alike. However in December 2019, skywatchers seen one thing unusual was taking place as Betelgeuse started to dim.
