Astronomy Picture of the Day - Terminator Moon

Explanation: What's different about this Moon? It's the terminators. In the featured image, you can't directly see any terminator -- the line that divides the light of day from the dark of night. That's because the image is a digital composite of 29 near-terminator lunar strips. Terminator regions show the longest and most prominent shadows -- shadows which, by their contrast and length, allow a flat photograph to appear three-dimensional. The original images and data were taken near the Moon by NASA's Lunar Reconnaissance Orbiter. Many of the Moon's craters stand out because of the shadows they all cast to the right. The image shows in graphic detail that the darker regions known as maria are not just darker than the rest of the Moon -- they are flatter.

Does the Terminator moon look like Arnold “Screw your Freedoms” Schwarzenegger?

Slightly odd view angle at least for people in North America. Normally we see the Mare Crisium near the edge at the upper right; here it’s shown at the far right.

The crater with the prominent, symmetrical rays in the 10 o’clock direction, about halfway out from the center, is Kepler. The big crater inboard of Kepler is Copernicus.

Tycho’s enormous ray system is invisible in this view, at least to my eye. I think Tycho is the nicely round crater with the prominent central mountain at about 7 o’clock in the picture, about three-quarters of the way out from the center.

Can you say that anymore? I am guessing that the current proper term is nonbinary astronomical illusion.

I agree, I checked one of my Moon Atlases, and I believe you are right on.
It’s a striking picture of the Moon, not one we would ordinarily see.
The LRO is so cool…

Would have been cool to see some of those impacts.

Tycho isn’t pictured.

There’s no mistaken Tycho. That huge crater with the three big gouge marks from what ever hit breaking into three chunks.

It is a beautiful picture, no doubt about it. Having a permanent orbiting telescope looking down at the surface of the moon from a height of just a few miles is indeed very cool.

I guess Tycho’s ray system is only prominent to us on Earth because of some sort of lighting effect. This picture was assembled from “terminator strips,” selected to place the angle sun’s angle very close to glancing in every part of the image. Whereas when we see the full moon in the sky, we’re seeing light reflected back at us from high in the lunar sky.

I would like to see a map of the Moon’s magnetic field superimposed on this picture....

Very long, pleasing, prominent shadow.

Those impact craters are huge. I would not want to be living on the Moon’s surface in a space exploration colony when another one of those big meteors crashed into the area.
