Mystery of Betelgeuse's dip in brightness solved

When Betelgeuse, a bright orange star in the constellation of Orion, became visibly darker in late 2019 and early 2020, the astronomy community was puzzled. A team of astronomers have now published new images of the star's surface, taken using the European Southern Observatory's Very Large Telescope (ESO's VLT), that clearly show how its brightness changed.

The new research reveals that the star was partially concealed by a cloud of dust, a discovery that solves the mystery of the Great Dimming of Betelgeuse.

It's possible the star Betelgeuse could explode in our lifetimes, perhaps next year (not 2012, because it's HARD to predict when a star is exactly a supernovae).

It's possible, but most astronomers think that it is thousands of years away from a supernova explosion. When astronomers say that Betelgeuse is close to going supernova they mean it is likely within the next 100,000 years.

not see if it has for another 650 years.

Bingo

 

Rarely if ever mentioned.

Almost like its omitted from articles. Although, it's just now being mentioned in passing here and there in the last few years in presentations etc.
