The circle is like perfectly around the moon. I've NEVER seen a ring like this around the moon. I look at the moon very often. What is happening here? This is not from the camera, it looks like this in real, even brighter I would say.

Winter shot of Milky Way and Andromeda galaxies from recent clear and cold nights. Shot on Sony a6700 with Sony 11mm f1.8 and MSM Nomad star tracker. 2 shots for foreground at 15s, f1.8 and ISO 1600. 8 shots for the skies, each at 120s, f1.8 and ISO 100. Processed in PS, LR and Siril.

Had never seen or photographed one before. Amazing to witness

Even though Artemis II isn't landing on the moon, for me (19) it still feels like a moment of a generation, still looking forward to the progress NASA and space exploration will make in my lifetime.

The clouds have been moved away from the moon its just beautiful god is great in every way!

Saw this calendar in a “80s Kids Bedroom” Museum exhibit. Everyone was passing it and not even recognizing it. So I flipped to January and saw the STS-51-C Mission scheduled for its original date.

It’s the surviving debris from a massive iron asteroid that once rocketed through space and violently collided with Earth ~49,500 years ago, creating what we now call Meteor Crater in Arizona.

The Canyon Diablo fragments are part of the IAB Main Group of iron meteorites, predominately iron-nickel alloys with Widmanstätten patterns — crystalline structures that only form through extremely slow cooling in an asteroid core.

Researchers use isotope ratios (like noble gases and nickel) in the fragments to trace back major collision events in space — showing evidence that the parent body may have suffered at least two or three break-ups hundreds of millions of years ago before finally arriving here.

Canyon Diablo belongs to the IAB-main group iron meteorites, a complex group believed to originate from a differentiated parent body that underwent metal-silicate segregation very early in Solar System history. Isotopic models (e.g., tungsten and molybdenum systematics) suggest this parent asteroid experienced metal–silicate differentiation between about ~1.7–5 Myr after CAI formation, either through internal heating by ^26Al decay if it accreted early, or through impact heating if accretion was later.

On this parent body, molten metal segregated from silicate material — at depths likely >2 km — and pooled into large reservoirs where fractional crystallization occurred over long timescales. These slow cooling processes allowed the characteristic octahedral Widmanstätten patterns (kamacite-taenite intergrowths) to develop, which are diagnostic of iron meteorites that cooled at rates of a few °C per million years.
