Neptune’s inner moons may have formed from the deep interiors of ancient icy satellites, new observations show. Learn more in #ScienceAdvances: https://scim.ag/4pGwU9f
Neptune’s inner moons and rings are exposed icy body interiorsTriton’s destructive wake exposed clay-like minerals from within ancient icy worlds, now reaccreted as Neptune’s inner moons.scim.ag

U.K. physics cuts may force iconic 1950s telescope to closeJodrell Bank Observatory is one of several projects to lose funding following a review by the cash-strapped Science and Technology Facilities Councilwww.science.org
NSF has decided to ban collaborations between every U.S. scientist it funds and nearly all Chinese research institutions and their employees. The new policy abandons NSF’s earlier attempt to balance the potential risks and benefits of such collaborations. https://scim.ag/4bw5Of5
New NSF policy would ban almost all collaborations with Chinese scientistsAgency drops attempt to mitigate risk in favor of outright prohibition on working with most Chinese research institutionswww.science.org
The protection of dark and quiet skies in the era of satellite constellations is an important topic today at #EAS2026Lausanne @eso.org’s Olivier Hainaut and others explain why
A disturbing vision of the future night sky: 'Each of the 50,000 reflectors would shine as bright as Venus, the brightest object in the sky after the Moon. In a light-polluted city, hundreds of these bright pinpricks would likely be the only “stars” visible.' By @danclery.bsky.social
Proposed new satellite fleets could overwhelm the night skyOrbiting data centers and sunlight reflectors would scupper astronomy by leaving streaks on telescope images and brightening skies, study findswww.science.org
Astronomy & Astrophysics has published a statement on the use of artificial intelligence (AI)-assisted technologies by authors in the journal. www.aanda.org/component/co...
"The goal is not just more capable AI, but AI that is more intelligible, accountable, and aligned with human aims. The window for achieving that future is narrowing," argue Eric Horvitz and Robert West in a new #ScienceEditorial. https://scim.ag/4oaIYig
A nice paper by @asborlaff.bsky.social showing that launching telescopes to space doesn't necessarily solve the light pollution issue from satellites. These are satellite trails seen by NASA's SPHEREx space telescope, which appear in 73% of all its images. Eek. arxiv.org/abs/2605.27501
Particle physicists in Europe intend to build a 91-kilometer-long circular collider—the largest accelerator ever—to smash electrons into positrons. https://scim.ag/4tZAFr3
It’s official: Europe physicists plan to build 91-kilometer particle colliderThe $19 billion Future Circular Collider would build on results from CERN’s Large Hadron Collider, currently the world’s largestwww.science.org
