Betelgeuse Is Being Weird Again. What Gives?

I thought you were talking about Beetlejuice, former Chicago Mayor Lori Light-in-the-loafers.

I agree. I hope to live to see it. Apparently supernova events happened throughout history and were cause for quite a significant stir.

[Doctor Congo]

The supernova will be as bright as the full moon for a while, and be visible during the day.

During those first three months or so, Betelgeuse will be so bright that it will be clearly visible during the day as well as the night; only after the fourth month or so will it become a nighttime-only object. And as it begins to fade from its brightness to look like a normal star once again, the extended structures should remain illuminated through a telescope for decades, centuries, and even millennia to come. It will become the closest supernova remnant in recorded history, and will remain a spectacular sight (and astronomical object of study) for generations to come.

It would be cool to witness a super nova. It would really light up the night sky for a while.

[Red Badger]

Yes, it has been estimated that it would be visible during the day, IF your section of the sky is pointed at Orion................

[Red Badger]

I hope it is in wintertime in the Northern Hemisphere.

Betelgeuse is in Orion’s shoulder and is directly visible at night then. Plus, here the air is usually clear that time of year......................

[glennaro]

Well, Betelgeuse was “being weird again” 642 years ago.

[SuperLuminal]

Going through the change of life can be a bitch...
Give her another million years and she will be ok...

Betelgeuse appears as a bright orange/red star in the upper left ‘shoulder’ of the constellation Orion. This red supergiant-type star is one of the largest you can see with your naked eye. It is one of the easiest stars to identify in the night sky thanks to its distinctive orange/red color, and position within Orion.
