Browsing: Betelgeuse
Betelgeuse is a red supergiant star located in the constellation Orion, easily recognizable as the bright, reddish star marking Orion’s right shoulder. It is one of the largest stars visible to the naked eye, about 700 times the size of the Sun and around 640 light-years away. Betelgeuse is thought to be nearing the end of its life and some expect to explode as a supernova within the next million years. Recent observations have shown significant variability in its brightness, sparking interest and speculation about its future. This variability is thought to be due to complex processes in its outer layers, possible ejections of gas or dust, or the effects of a stellar companion.
