What Hacker News says?
> It also means that No, it doesn't mean that. What makes 'Oumuamua special is not the fact that we didn't see interstellar objects before. It's rather the fact that 'Oumuamua has highly unusual and hard to explain properties. Avi Loeb: > ‘Oumuamua exhibited a non-gravitational acceleration of 4.92 ± 0.16 × 10^⁻6 m/s² that decreased proportionally to 1/r², where r represents the heliocentric distance, corresponding…

HN discussionRelated to this is Loeb's proposal to nudge the Juno spacecraft, currently orbiting Jupiter and soon facing EOL, into the path of 3I/Atlas to try to scan it and snap some pictures. I doubt it has enough fuel left, but I hope they're looking into it. https://avi-loeb.medium.com/how-close-can-the-juno-spacecraf...

HN discussionAvi Loeb is an interesting scientist. I read a longer article about him that gave some more background about his work [1]. While he is famous for going on podcasts and making wild claims about objects being signs of alien intelligence, the actual hard science that he's doing is interesting. E.g, this expedition he managed to get funding to recover these extrasolar particles. The clickbaity pop media says that this i…

HN discussionThis article is late to the party. I would hardly call SETI leading edge alien detection tech today. Our best bet would be to look at our recent interstellar visitor 3I/Atlas and to use other modern instruments to detect remnants or signatures of past intelligent activity. It's very likely given the age of the universe and the number of known habitable zone planets that other life forms did evolve and live there (or…
