Photographer Eric Brummel created this magnificent time-lapse video of the Milky Way in which the sky is stabilized so you can experience the Earth's rotation. He captured the footage at Font's Point, Anza-Borrego Desert State Park, California. From Universe Today:
Eric created this time-lapse by using a star-tracker with his camera. A star-tracker rotates the camera at the same speed as the Earth, but in the opposite direction. It has the visual effect of stabilizing the sky. Usually, star-trackers are used to stabilize the camera during a long exposure, to avoid blurry or streaked stars in the image.

Amateur astrophotographer Ethan Chappel was using his telescope to look for Perseid meteors on Wednesday night when he happened to capture an image of something very large slamming into Jupiter. It was most likely a massive meteor. From Sky and Telescope:
After running the camera data through a program designed to alert the user to just such transient events, Chappel spotted a flash of light in the planet's South Equatorial Belt (SEB). It expanded from a pinpoint to a small dot before fading away — telltale signs of a possible impact based on previous events observed at Jupiter....
If confirmed this would be the 7th recorded impact at the solar system's biggest planet since July 1994, when 21 fragments of Comet Shoemaker-Levy 9 slammed into the planet in succession to create a rosary of dark impact boils visible in amateur telescopes.

Ralf Vandebergh captured an image of the US Air Force's X-37B space plane in orbit. The reusable, uncrewed space vehicle, designated OTV-5, is on a secret testing mission since its launch in September 2017. From Vandebergh's
post at Spaceweather.com:
I have been hunting for the OTV-5 since months and saw it visually in May. When I tried to observe it again mid June, it didnt meet the predicted time and path. It turned out to have maneuvered to another orbit. Thanks to the amateur satellite observers-network, it was rapidly found in orbit again and I was able to take some images on June 30 and July 2. This most recent pass was almost overhead. The OTV is a small version of the classic Space Shuttle, it is really a small object, even at only 300 km altitude, so dont expect the detail level of ground based images of the real Space Shuttle. Considering this, the attached images succeeded beyond expectations. We can recognize a bit of the nose, Payload Bay and tail of this mini-shuttle with even a sign of some smaller detail.
Images were taken through a 10 inch F/4,8 aperture Newtonian telescope with an Astrolumina ALccd 5L-11 mono CMOS camera. Tracking was fully manually through a 6x30 finderscope.

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.

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.
