Scientists believe that 3I/ATLAS, a rare comet, is not alone and that more interstellar objects may be on their way.
Astronomers have detected 3I/ATLAS, one of the rarest comets observed, and suggest that more interstellar visitors could soon be discovered.
New detection methods are expected to reveal that such visits are more common than previously thought, despite 3I/ATLAS being only the third confirmed interstellar object.
As 3I/ATLAS passes Mars and approaches Earth, it will be obscured from view as it travels behind the Sun.
Such discoveries are likely, thanks to advanced new detection methods.
Author's summary: Comet 3I/ATLAS approaches Earth, possibly with others.
