Astronomy Picture of the Day - Terminator Moon: A Moonscape of Shadows

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 featured image is a digital composite of many near-terminator lunar strips over a full Moon. 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 overlay images were taken over two weeks in early April. 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 also flatter.

That’s a fantastic picture. My Grandpa was an avid backyard astronomer in the 1970s and passed away all too early back then. He would have loved to see the images we’re able to get now.

I hate when a Terminator moons you.

If there were female Terminators it wouldn’t be horrible.
Sarah Connor in her prime would be really nice.

At 2:14 A.M. it becomes self-aware...

WOW! That picture is so clear I can see my vacation home!

JK, It’s on the dark side, I can never see it from earth. That is a great picture, though.

It’s on the dark side

...far side...

It gets the same amount of light as the side facing Earth.

I prefer shooting lunar images that include the terminator for contrast etc.

Crater Copernicus at center

Copernicus is about 58 miles in diameter. The crater floor is about 2.4 miles below the crater rim crest. Mountains rise from the center of the crater to a height of about 4,200 feet. An impact this size on earth today would triggered a mass extinction event.

A comparison image of Copernicus taken by NASA/lunar reconnaissance orbiter LRO.

Great job! If you have Instagram, the photographer used a 6” Celestron and he describes the process he used to capture such an incredible image.

Not a whole lot of difference between your photo and the LRO.
