Its not aliens, its probably just outgassing! Here&#x27;s the first public paper I could find off hand on the topic. The acceleration due to outgassing of 67P/Churyumov–Gerasimenko (of Rosetta spacecraft fame) https://arxiv.org/abs/1902.02701 While I haven&#x27;t personally seen anything that decides if Oumuamua counts as a comet or not, thats beside the point, since anything can outgas with enough heat. It appears to be covered with Tholins (based on the spectroscopy https://arxiv.org/abs/1712.06552) which aren&#x27;t immune to outgassing, and likely make up at…</p><p><a href="https://hackerpaper.kaipfister.de/p/1902.02701/">Paper and discussion history</a>.
