New telescope images provide best evidence yet that the bright red star Betelgeuse is actually 2 stars in disguise
SMRTR summary
Betelgeuse, the famous red star in Orion's shoulder, may actually be two stars. Astronomers using the European Southern Observatory's Very Large Telescope captured images in December 2024 of a faint companion star, nicknamed Betelgeuse B, orbiting very close to it. The companion is two to three times heavier than our sun, and scientists believe it may influence how Betelgeuse eventually explodes as a supernova.
