Thanks to Chris Young at Interesting Engineering for the chance to contextualize 3I/ATLAS. I would have preferred two thumbnails of the comet itself, but... enjoy.

3I/ATLAS: A city-sized alien spacecraft or simply the ‘coolest comet’ ever seen?
Harvard professor Avi Loeb claims 3I/ATLAS could be an alien spacecraft. Arizona State University professor Steven Desch is sure it isn't.

Avi Loeb's calculations about 3I/ATLAS are 100% wrong because he has never understood that dust in the tail(s) responds to solar radiation pressure. Solar wind shapes the ion tail. But the radiation pressure is about 1000 times larger than the solar wind ram pressure, for particles that feel it.

New morphology in the tail of comet 3I/Atlas will inevitably be spun by the quack Avi Loeb as some evidence of alien activity. This is nothing new, we've seen similar behavior in other comes including 17P, C/2016 R2, and C/1961 R1, and others. It's ionized carbon monoxide. #3I #3I/Atlas #Comet 🔭

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.

Have spent a substantial portion of the day turning down requests to comment to the media on Loeb's claims that 3I/ATLAS might be artificial. What was a really interesting science story has been ruined by one man ignorantly shouting. So frustrating.

🌟 Comet 3I/ATLAS brightens rapidly! 🌟
As it reached perihelion on Oct. 29, spacecraft watching the Sun saw a sudden surge in brightness. Scientists expect it to emerge from solar conjunction much brighter and easier to see from Earth. 🔭

Sorry, but interstellar visitor 3I/ATLAS really is a comet, not aliens Interstellar objects like 3I/ATLAS are exciting, but there is no reason to claim that they are evidence of alien spacecraft – sometimes a comet is just comet, says Robin George Andrews
