Harvard astronomers theorize that a meteor that struck Earth's atmosphere in 2014 could have been from another solar system, judging by what scientists know about 'Oumuamua, an interstellar object that zipped through our solar system in 2017. (An artist's depiction of 'Oumuamua is seen here.)

An Interstellar Meteor May Have Collided With Earth in 2014

Researchers have identified an object that, they theorize, was traveling too fast to have originated within our solar system
