I thought I read that a supenova releases intense gamma ray jets.
If aimed at earth, might not be so harmless?

Women and minorities hardest hit.
And, of course...
Trump’s fault!

Betelgeuse has the cool name, but it never made the hit parade in celestial navigation.
And it's because Betelgeuse was not as bright as other stars around Orion.
You see, a sextant can only get an accurate navigational fix only two times of day: sunrise and sunset. (not counting Sun and planet fixes)
Around sunrise and sunset there's often a very narrow window of time (maybe 20 minutes?) when the sextant user has a clear enough horizon to accurately measure the angular height ( in degrees ) between the star and the horizon.
Ideally you need three good sightings where the stars (or planets) are located at wide enough horizontal distance from each other to create a triangular fix on your navigation chart.
I bought a sextant once because I was in the Navy and thought sextants were cool tools. And I read a great little book:
How to Read the Night Sky by W.S. Kalswhich (out of print)
The value of that book boiled down one key sentence I have remembered for 50 years:
Captain, All de Rigging Seems Properly Polished.
Hover your mouse over the words above to see the brightest "navigation-ready" stars around Orion.
If you memorize that little ditty and the circular path of finding them in the night's sky, you have little trouble getting accurate celestial readings
Now I understand a clever high school teacher added to the mnemonic to loop back to Betelgeuse. Here it is:
Captain, All de Rigging Seems Properly Polished using Cast-off BeetleJuice.
And here's a Britannica link showing the brightest stars in night sky.

So like squashing a bug, there will be beetle juice everywhere.

*Halley’s Comet was a bust. Definitely, but Hale-Bopp and Hyakutake more than made up for it, though 10 years later.

Orion appears “upside-down” when visible in the southern hemisphere.
