Impending Explosion: Our Fascinating Star Draws Near.

Betelgeuse, a red supergiant star in the constellation Orion, is known for its brightness fluctuations and is inching closer to a grandiose collapse and stellar explosion, known as a supernova. While it's uncertain when this will happen, historical records suggest it might not explode for a long time. When it does explode, it will be visible to the naked eye and will be the brightest star in the sky for around 100 days. Other red supergiants in our galaxy, like Eta Carinae, might erupt before Betelgeuse.
