Why are planetary scientists, astrobiologists and and SETI scientists so negative (pissed off, even) about Avi Loeb’s repeated claims that 3I/Atlas may be an invading alien spaceship?

An incredible discovery. The first ever image of a baby exoplanet embedded in the dust rings from which planets are forming around a star. Confirms the developing view of planet formation that we’ve never before seen in action.

I think democrats should push for a thorough review of all Elon Musk govt contracts as part of their 2026-8 portfolio. Why are taxpayers financing the work of a racist near-trillionaire? Leaving that unexamined was one of the biggest failures of the last Dem majority.

I’m sorry to learn that Donna Jean Godchaux has died. Her exuberant harmonies with the Grateful Dead in the 1970s enriched and elevated the band’s vocal sound during their most consistently great decade of performances. When she was on (not every night…) it was frequently pure heart of gold magic.

Oh, I find this story strangely encouraging. I’ve long wondered if the planets around dead stars are permanent dead-end sinks of the potentially life-supporting elements they have accumulated, keeping these useful atoms away from the composting stellar recycling of a living galaxy.
Perhaps not…

An interstellar comet is such a cool find. It’s really a shame the bright nucleus of this wondrous appearance has been surrounded by an obscuring coma of alien conspiracy.
The Harvard astronomer responsible for that is doing sizable harm to the fields of speculative science he claims to represent.🧪

3I/ATLAS is behaving just as a comet should. No shenanigans. Looking forward to the possibility of JUICE (a European spacecraft heading eventually to Jupiter) observing this object in the coming weeks!
I have just received from Kevin Walsh of SWRI a re-analysis of the PUNCH data for 3I/ATLAS, & have redone our gas and dust coma prediction models as a result. These new data agree well with the independent reductions of Thomas Lehmann and bode well for the Juice observations starting November 2nd.
