That report doesn't seem right.
"But measurements made since then using the same instrument show that Betelgeuse is now only about as wide as the orbit of Venus - a size reduction of about 15 percent in 15 years."
If Betelgeuse was the size of the orbit of Jupiter, and now is just the size of the orbit of Venus, that is a massive contraction, much more than a mere 15%. If I was living in the neighborhood I would be worried. I would consider moving.
Preferably move somewhere around 2000 light years away, which makes the Earth, at only 600 light years away, a little too close for comfort.
I think we should move too!
