The Moon Is Flipped Upside Down in the Southern Hemisphere

posted by Jason Kottke   Nov 21, 2018

How old were you when you learned that the Moon in the Southern Hemisphere is upside down? I was today years old…this is my head exploding —> %@*&!$. Ok, the Moon isn’t upside down (that’s Northern-ist) but its orientation changes depending on if you’re north or south of the equator.

“From our perspective, the Moon and the night sky is actually rotated 180 degrees compared to our Northern Hemispherical friends,” Jake Clark, an astronomer from the University of Southern Queensland in Australia, explained to ScienceAlert.

“In the south we see the Moon’s dark ‘Oceanus Procellarum’ sea in the south-east corner compared to in the north-west corner for a northern observer.”

But why does it look like this? Well, because physically, we’re actually upside down compared to someone standing in the opposite hemisphere.

That makes perfect sense & the explanation is quite simple but it’s still messing with my head. How did I not know this? Here’s how the Moon appears in the Northern Hemisphere (from Wikipedia):
