🚀 3I/ATLAS: NOT A SPACESHIP. JUST A COMET.
“Non-gravitational acceleration” doesn’t mean aliens—it means outgassing. A new AAS paper shows interstellar comet 3I/ATLAS behaves like a normal comet, with icy jets giving it a gentle push. Mass, size, acceleration? All ordinary physics.

Another canary in the collapsing coalmine.
A paper today in Nature by Borlaff et al. on the impact of ever-increasing numbers of satellites in low-Earth orbit on space telescopes like Hubble, SPHEREx, & CHEOPS today, & Xuntian & ARRAKIHS in the future.
The number of proposed satellites is eye-watering, & the effects on astronomy horrendous – there are wider effects on pollution of the upper atmosphere & safety of key orbital assets as well.

From Voyager 2’s smooth blue-green view in 1986 to Webb’s breathtaking 2023 image, our vision of Uranus has transformed. Keck (2002) revealed faint rings, Hubble (2022) showed brighter tones and weather patterns, and Webb unveiled glowing rings and a luminous atmosphere.

Hundreds of NASA employees and supporters have signed the #VoyagerDeclaration, formally expressing dissent against budget cuts and attacks on key NASA missions.
This action follows similar statements from #NIH and #EPA communities, voicing objection to the unlawful policies of the Trump administration.
