It appears that they really are rings, not spherical. That astounds me! Equally astounding is that the plane of the rings appears to be nearly normal (perpendicular) to our line of sight. Just Wow!

New Webb Image Captures Clearest View of Neptune's Rings in Decades - NASA Science

NASA’s James Webb Space Telescope shows off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this distant planet’s rings in more than 30 years, but its cameras reveal the ice giant in a whole new light.

Most striking in Webb’s new image is the crisp view of the planet’s rings – some of which have not been detected since NASA’s Voyager 2 became the first spacecraft to observe Neptune during its flyby in 1989. In addition to several bright, narrow rings, the Webb image clearly shows Neptune’s fainter dust bands.

“It has been three decades since we last saw these faint, dusty rings, and this is the first time we’ve seen them in the infrared,” notes Heidi Hammel, a Neptune system expert and interdisciplinary scientist for Webb. Webb’s extremely stable and precise image quality permits these very faint rings to be detected so close to Neptune.

DART is the NASA mission that sent a speeding box to crash into an asteroid to deflect it (planetary defense!). I watched the "event" live this evening.

DART goes silent after hitting an asteroid [Update]

Details of the impact aren't yet here, but the probe's last image indicates success.

In that view, I assume the "box" hit the asteroid head on, that the debris of the collision kept traveling in the same direction as the asteroid, and that it outpaced the asteroid slightly, expanding to the left. All korrekt?

Swedish Man Arrested For Trying To Build Nuclear Reactor In His Kitchen

Police arrested the man after he called the Swedish Radiation Authority to ask whether splitting atoms at home was legal. After his arrest and after police took his radioactive material, he said he would keep his projects "theoretical."

Astronomers Discover Closest Black Hole to Earth - Gemini North telescope on Hawai‘i reveals first dormant, stellar-mass black hole in our cosmic backyard

Astronomers using the International Gemini Observatory, operated by NSF NOIRLab, have discovered the closest-known black hole to Earth. This is the first unambiguous detection of a dormant stellar-mass black hole in the Milky Way. Its close proximity to Earth, a mere 1600 light-years away...

I am fairly certain Australia is another planet, so why not Pluto?
