A newly discovered comet has astronomers excited. Formally named C/2019 Q4 (Borisov), the object appears to have come from outside our solar system. If confirmed, that would make it the second known interstellar visitor to our solar system, after the space rock ʻOumuamua.

Astronomers first found Comet C/2019 Q4 on August 30. The past week of observations, including this image taken by the Canada-France-Hawaii Telescope on Hawaii’s Big Island, have increased astronomers confidence that the comet started life in another solar system.
