I had to look it up.

Interesting.

The explosion is in all directions but the collapse to the black hole and the resultant GRB shoots out the poles. I did read an article in recent years that said one of Betelgeuse’ poles is pointed almost directly at us but that at 640 light years away the actual direction of the pointing is too difficult to determine precisely. If the collapse is of a certain type and it is pointed directly at us, it could strip away our atmosphere.

It’s an interesting movie, if you get the chance.

Betelgeuse has a 30 year rotation, and the star's axis isn't pointing anywhere near us.

A Gamma Ray Burst is not associated with a Betelgeuse-type red supergiant explosion. GRBs are short lived events that are believed to be caused by the catastrophic collision between two stars spiraling in on each other, typically neutron stars, or the explosion or a Wolf-Rayet type star.

I thought I heard it said that it could be in the next 200,000 years....hard for a non-scientist to get excited about it today....

"Similar dimming events have occurred before, reducing the brightness of Betelgeuse below even what it currently is at."

Whoever wrote this thing must have slept through grammar class.
