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:

The value of that book boiled down one key sentence I have remembered for 50 years:


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:


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.

turning a link into a live link does not, alas, work in an initial post. As Beetlejuice might say, “don’t you hate it when that happens?”

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