A young, bright star has been acting a little erratic lately.
The star, Betelgeuse, is suddenly dimming. It may be a sign, astronomers say, that the star is about to explode. Another possibility is the red supergiant may just be going through a phase.
Ed Guinan, an astronomy professor at Villanova University, was the lead author on a December 8 paper entitled “The Fainting of the Nearby Supergiant Betelgeuse.”
He told CNN that Betelgeuse (pronounced: BAY-tel juice) been declining in brightness sharply since October, and was now about 2.5 times fainter than usual. Once the ninth brightest star in the sky, Betelgeuse has fallen now to about the 23rd brightest.
