A very interesting little clip. If Betelgeuse does go supernova, the light would be fantastic. Maybe brighter than the full moon. The whole clip is worth watching (very short) as it talks about the supernova of 1054...which is new to me. I had never heard about this!! At the 7.58 mark, an interview takes place where the scientist describes what a Betelgeuse supernova would likely look like.

It got me thinking about the Day of the LORD in Zechariah 14. 2nd link below. It's just a thought!!  Natan testified that he was told that this phenomenon of constant daylight - no nightfall - would occur on the day Israel is attacked. The day that Messiah Jesus touches back down on the Mount of Olives.

What Happens if Betelgeuse Explodes?

Zechariah 14:7 It will be a day known only to the LORD, without day or night; but when evening comes, there will be light.
