One of the biggest and brightest stars in the night sky will momentarily vanish as an asteroid passes in front of it to produce a one-of-a-kind eclipse.
There are lingering uncertainties over those predictions as well as the size of the star and its expansive atmosphere. It's unclear if the asteroid will obscure the entire star, producing a total eclipse. Rather, the result could be a "ring of fire" eclipse with a miniscule blazing border around the star. If it's a total eclipse, astronomers aren't sure how many seconds the star will disappear completely, perhaps up to 10 seconds.
Sounds very interesting to anyone with a telescope in a cloud free area.
