Ah, because what we really need in 2023 is a deep dive into Jupiter's "mushballs" — sounds like a bad sci-fi dessert! 🍨 Apparently, it's crucial we know that the gas giant is just a cosmic slushie with an identity crisis. 🌌🤦‍♂️

ScienceDailyOn Jupiter, it's mushballs all the way downObservations of Jupiter show that ammonia is unevenly distributed in the upper atmosphere, against expectations of uniform mixing. Scientists found evidence for a complicated but apparently real process associated with fierce lightning storms: strong updrafts generate slushy, ice-coated hailstones of ammonia and water that eventually plunge into the planet and deplete areas of ammonia. This is part of the first 3D picture of the planet's atmosphere, which shows storms are primarily shallow.

@planet4589 : "When I was a kid 🧒, it was #LEO. Now, the frontier is out near the #asteroid belt, and the #Moon and #Mars are becoming part of where humanity just hangs out, maybe not yet as people, but with #robots. Meanwhile, #LEO is so normalized that it doesn’t take a #SpaceAgency to deal with it. You just call #SpaceX. Thousand years from now, perhaps more people live off Earth 🌌 than on it" cearkadia.edu.pl/jonathan-mcdo

A small treat for the weekend.

In the late evening of 24 April 1972, Apollo 16 left lunar orbit carrying John Young, Thomas Mattingley II, & Charlie Duke back to Earth.

The Apollo Metric (Mapping) Camera took a sequence of still images looking back at the Moon, initially the lunar farside & then the nearside as it rotated into view.

Here's a 10 fps movie sequence showing 90 of those images without any processing or alignment.
