James Webb Telescope Observes Red Supergiant Star Before Supernova

Astronomers using the James Webb Space Telescope (JWST) have observed a massive red supergiant star on the verge of exploding as a supernova, providing new insights into a long-standing astrophysical mystery. Although red supergiants are expected to produce many supernovae, they are rarely observed ... [More info]

An article published in the journal "Astronomy & Astrophysics" reports the creation of a detailed image of the red supergiant star WOH G64 and its surroundings, the first ever obtained of a star outside the Milky Way. A team of researchers led by astrophysicist Keiichi Ohnaka used the GRAVITY instrument on ESO's VLTI in Chile to obtain details of this star in the Large Magellanic Cloud.

Betelgeuse is Almost 50% Brighter Than Normal. What's Going On?

Betelgeuse will explode as a supernova and Orion will never be the same. That much is certain. But when will it explode?
