Since it's Friday, and things have been a tad serious around here for the past few days (as they often are), time for a little TGIF diversion.
As the thread title suggests, here are a couple of odd things about
the moon I came across while websurfing recently, and, while not exactly earth-shaking (and that's arguably a good way to put it), they are actually sort of interesting. I suspect few people know about
, or have spent a lot of time thinking about
either of them.
First, people who live in the southern hemisphere see the moon at night upside down
from the way we see it here in the northern hemisphere.
The article linked below explains the geometry of why this is true (I didn't believe it was myself at first, but it is), giving us a graphic to demonstrate it. Which is useful, as most of us will never have the opportunity to visit in the other hemisphere and observe this phenomenon for ourselves.https://www.sciencefocus.com/science/does-the-moon-look-upside-down-in-the-southern-hemisphere/
Again, not something that anyone is going to spend a whole lot of time contemplating, but maybe it's odd enough to bring up in a conversation sometime, or something.
BTW, this phenomenon is also true for any of the stellar constellations near the celestial equator that can be seen from both hemispheres. The constellation of Orion, for example, looks upside down when seen in Australia.
And second, speaking of curious lunar phenomena that one actually can
observe, here's one you may not have known about
, but which you can indeed verify for yourselves.
During the next full moon, go outside with a newspaper, book, or other print material,
open it up, and, standing there in the darkness, start reading it by the light of the full moon! Yes, you can actually do it! A full moon puts out that much light!
Ah, the wonders of nature!
Have a good Friday, everyone!
