That would be big news because a supernova hasn’t been seen in our galaxy since the 17th century, but it wouldn't be dangerous—Betelgeuse is well beyond the 50 light-years “supernova danger ...

And unlike most stars, we can see it changing, in part because it's relatively nearby in our galaxy. Betelgeuse is known for ...

NASA's powerful Webb Telescope has spotted more than 40 ancient stars in a distant galaxy, researchers said in a new study. The study, published Monday in Nature, said the researchers used a ...

A supernova hasn’t been seen to explode in our Milky Way galaxy since the 17th century. Betelgeuse will inevitably explode as a supernova, but that could occur at any time in the next 100,000 years.

This figure shows measurements of Betelgeuse's brightness from different observatories from late 2018 to present. The blue and green points represent data from ground-based observatories.
