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
Saturn’s icy moon Enceladus is of great interest to scientists due to its subsurface ocean, making it a prime target for those searching for life elsewhere. New research led by Carnegie’s Doug Hemingway reveals the physics governing the fissures through which ocean water erupts from the moon’s icy surface, giving its south pole an unusual “tiger stripe” appearance.
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.
This is the first clear image of a planet caught in the act of formation. The star, PDS 70, is blacked out at the center of the image, while the planet, PDS 70b, is visible as a bright dot to its right. Astronomers just discovered a second newborn planet circling PDS 70.
