"By far, the most likely outcome will be that 3I/ATLAS is a completely natural interstellar object, probably a comet," he wrote in the blog post. A look at 3I/ATLAS from NASA.

Interstellar comet 3I/ATLAS shines in the sharpest view yet captured by the Hubble Space Telescope, helping astronomers determine the object’s size.

For instance, when the first interstellar object ever detected in our solar system was spotted in 2017, Loeb similarly posited that it was of extraterrestrial origin – a theory later debunked.
