Cloud streets over the Labrador Sea.
The image was taken with good conditions on February 5, 2020. The play of shadows near the south lunar pole gives relief to the craters. Equipment: Skywatcher 254/1200 telescope (0.18 “/ p), ASI178M, Baader Q-Turret X2.25 barlow and Baader green filter. Stack of 300 images with AS!3. The final image is presented with its acquisition size. Best regards.
Over the last five years I’ve collected eclipses with this single composition in mind. I call it “Cyclipse”. It’s made of a total solar eclipse, partial solar eclipse, total lunar eclipse, and waxing crescent Moon. It feels so good to see it come together over the years. #eclipse
Fantastic science themed pictures.

The far side of the Moon is surprisingly different. The most striking difference evident in the Luna 3 pictures is the absence of the large, dark seas of cooled lava, called maria, that cover a substantial fraction of the Earth-facing near side. The far side is instead densely peppered with impact craters of every size and age.

Dunes come in various characteristic shapes on Mars just as on Earth, providing clues about the prevailing wind direction. Monitoring them over time also gives us a natural laboratory to study how dunes evolve, and how sediments in general are transported around the planet.

In the clear water of the Red Sea, a shoal of bigeye trevally circle 80 feet down at the edge of the reef. For the past 20 years Alex has travelled here, to Ras Mohammad—a national park at the tip of Egypt’s Sinai Peninsula—to photograph the summer-spawning aggregations of reef fish. This time, it was the high numbers of bigeye trevally. Their circling behavior is a dating exercise prior to pairing up, though it also deters predators. Alex captured the shape of the shoal against the deep blue water below, the iridescent angled fish reflecting the light from the sun and his strobes.
