Strangely Behaving Red Supergiant Betelgeuse Smaller and Closer Than First Thought

“It’s burning helium in its core at the moment, which means it’s nowhere near exploding,” Dr. Joyce said.

“We could be looking at around 100,000 years before an explosion happens.”

Co-author Dr. László Molnár from the Konkoly Observatory?in Budapest says the study also revealed how big Betelgeuse is, and its distance from Earth.

“The actual physical size of Betelgeuse has been a bit of a mystery — earlier studies suggested it could be bigger than the orbit of Jupiter. Our results say Betelgeuse only extends out to two thirds of that, with a radius 750 times the radius of the sun,” Dr. Molnár said.

“Once we had the physical size of the star, we were able to determine the distance from Earth. Our results show it’s a mere 530 light years from us — 25 percent closer than previously thought.”

The good news is Betelgeuse is still too far from Earth for the eventual explosion to have a significant impact here.

I forgot Holmes. That was quite interesting. I could see it from my back yard in the middle of town. There will be more!

Not really. Joke at their expense since they were to blame, no one else. Idiots.

I just knew something wasn’t right when I looked at it.
