The scientist/artists in NASA's Scientific Visualization Studio created this magnificent video to accompany a recent performance by the National Symphony Orchestra Pops of Claude Debussy's "Clair de Lune." From NASA:

The visuals were composed like a nature documentary, with clean cuts and a mostly stationary virtual camera. The viewer follows the Sun throughout a lunar day, seeing sunrises and then sunsets over prominent features on the Moon. The sprawling ray system surrounding Copernicus crater, for example, is revealed beneath receding shadows at sunrise and later slips back into darkness as night encroaches...
The visualization uses a digital 3D model of the Moon built from Lunar Reconnaissance Orbiter global elevation maps and image mosaics. The lighting is derived from actual Sun angles during lunar days in 2018.
The Royal Museums Greenwich announced the shortlisted images from their Astronomy Photographer of the Year 2018 and the photos are absolutely breathtaking. They'll announce the winners in October. See more at: Insight Investment Astronomy Photographer of the Year 2018 shortlist gallery

On Saturday, space photographer John Kraus, age 17, captured this magnificent image of the International Space Station transiting the full moon. He took the photo using a Nikon D500 and Nikkor 200-500mm lens on an equatorial mount used for astrophotography. This wasn't a lucky shot. It took John weeks of planning. From Kraus's article at Petapixel:
As the ISS orbits Earth at 17,500mph, or roughly five miles per second, the transit lasted just 0.90 seconds.
This transit was visible from a narrow path stretching from the middle of Florida to the east coast. I was stationed in a very specific location, as being just several tenths of a mile can throw off a planned transit photo.
Given that the transit occurred so quickly, and I was in such a specific location, it’s natural to ask how I calculated the information required to take this photo. Luckily, I didn’t have to, as there’s a website dedicated to finding out transit info.
