Betelgeuse: A Chaotic Star Nearing Its Violent End.
TL;DR Summary
Astronomers have observed a chaotic star, BELLS 1, in the Triangulum galaxy that is transitioning into a highly unstable Wolf-Rayet star. The star has begun beaming a new signal indicating that it is churning either carbon or iron deep within it through nuclear fusion, and is inching closer to its eventual fate of exploding into a spectacular supernova. BELLS 1 is shedding about 10 solar masses' worth of star matter every million years or so, which is pumped back into the nearby universe, triggering the formation of future generations of stars and enriching them with recycled elements.
