Mystery Surrounds Strange Behavior of Supergiant Star Betelgeuse.

Betelgeuse, a red supergiant star located in the constellation Orion, is shining 50 percent brighter than usual, and scientists are monitoring the situation closely to understand the change better. A new research paper suggests that Betelgeuse is in the late stage of core carbon burning and a good candidate for the next galactic supernova. However, it is difficult to determine when Betelgeuse will go supernova since the star pulses, ejects material, rotates, and is also a runaway star speeding through space.
