Near star could soon explode science space
Dr Boyce said if it does do that, Betelgeuse will give off more light than the Milky Way, more energy than it collectively has over the millions of years it’s been alive, and be the brightest object in the sky.

Decin et alSome were quick to point out that Betelgeuse is classed as a semi-regular variable star, meaning its brightness is prone to change.
But researchers from Villanova University said Betelgeuse reached its lowest ever brightness level earlier this month. “This season shows the star has been declining in brightness since October,” a note from Villanova astronomy professor Edward Guinan posted on“Betelgeuse undergoes complicated quasi-periodic brightness variations with a dominant period of approximately 405 – 435 days. But also Betelgeuse has longer-term and shorter term smaller brightness changes. Currently this is the faintest the star has been during our 25-plus years of continuous monitoring,” the note said.
