Betelgeuse still appears to be recovering from the event. The 400-day pulsation rate that has been tracked by scientists for 200 years is gone, and the star itself is bouncing as it reforms.

Betelgeuse is now so huge now that if it replaced the sun at the center of our solar system, its outer surface would extend past the orbit of Jupiter. Dupree used Hubble to resolve hot spots on the ...

The Hubble Space Telescope has captured a never-before-seen phenomenon following a titanic ejection of Betelgeuse’s surface calculated at 400 billion times the mass of a solar flare.
