There aren't many photos showing Neil Armstrong on the Moon during the #Apollo11 moonwalks, simply because Neil took most of the photos. This one—a crop and edit of AS11-40-5894—shows Neil in the shadows next to the LM. There's noise and glare from the film scanner, but it's him.

@BrianRoemmele I debunked this a few years back. It’s a calm pond with dirt poking out of it. You’re seeing the dirt reflecting off itself.

Al atardecer, se capturó una hermosa alineación entre un arcoíris y una montaña.
La majestuosa sombra de la montaña parece apuntar al centro del elegante arco. Debido a la perspectiva y la línea de visión, la sombra de la montaña forma naturalmente una figura triangular cónica, con su ápice posicionado en el punto opuesto al Sol en el horizonte. Después de las tormentas eléctricas en la región, el arcoíris se formó con su característico arco de 42 grados, a medida que la luz solar es refractada y reflejada por las gotas de agua atmosféricas.

At the @NASAAmes booth at Open Sauce they had sections of the Orion heat shield from Artemis 1 and 2 side by side for comparison. So you can see the spallation effects up close.

Schiller Crater: The Moon’s Elongated Enigma
Nestled on the southwestern near side of the Moon you will find one of the oddest looking craters on the lunar surface. Measuring 179 km long by 71 km wide, Schiller's strange form sets it apart from far more common circular impact craters.
This strange elongation likely stems from the merger of multiple craters, further emphasized by its position near the lunar limb. The crater boasts terraced inner walls and a mostly flat floor flooded by ancient lava. A striking double ridge runs through the northwest section of the floor. At about 2.5 km deep, Schiller offers a fascinating look at the Moon’s ancient past.
This view is captured approaching local sunset across the region.

Lunar South-West Libration Zone
After capturing Saturn on the 9th, I turned my telescope to the Moon and recorded what is easily my best image yet of this elusive libration zone, revealing features that only swing into view for a short time thanks to the Moon’s natural wobble.
In the upper left is Hausen (163 km). Just below and to its right lies the vast walled plain Bailly (300 km), the largest such feature on the lunar near side. Time has worn it down so thoroughly that only a faint, ghostly outline remains.
Off to the upper right is Drygalski (162 km). Both Drygalski and Hausen would rank among the most impressive craters on the near side if they were located in more favorable positions.
The real bonus that morning was the near-perfect lighting, which beautifully revealed the subtle topography across the whole region.

#PPOD: The Tallest Peaks 🪐
Vertical structures, among the tallest seen in #Saturn's main rings, rise abruptly from the edge of Saturn's B ring, casting long shadows on the ring in this image taken by NASA's @CassiniSaturn two weeks before the planet's August 2009 equinox.
Part of the Cassini Division, between the B and the A rings, appears at the top of the image, showing ringlets in the inner division.
Cassini scientists believe this is a prominent region at the outer edge of the B ring where large bodies, or moonlets, up to 1 kilometer in size are found. It is possible that these bodies significantly affect the ring material streaming past them, forcing the particles upward in a "splashing" manner.

✨What you see is the protostar HH 211. It's about 35,000 years old, only 6% the mass of the Sun, and located 1,000 light-years away.
It has a bright bipolar jet, and it's one of the few known cases where a magnetic field has been detected ➡️almaobservatory.org/en/audiences/a…

A new result using NASA’s @chandraxray shows that the outer spiral arms in the Milky Way galaxy may reach wider than previously thought. This finding may lead astronomers to adjust their understanding of our home galaxy’s structure.
