Space explorers have found another mystery. The Shrinking Betelgeuse
! This red supergiant in the constellation of Orion appears as a bright star to the naked eye observer. It has been found to be shrinking for the last 15 years. By now it has shrunk 15% that is by the size of the Venus orbit!
Generally stars that shrink should become hotter and thus brighter. However no increase in brightness has been seen.
There are speculations, will it implode or explode?? Or maybe we are yet to learn something new in the life of stars.
