Scientists have come up with a simple explanation for the strange movements of our solar system's first known visitor from another star.
In October of 2017, astronomers in Hawaii spotted an object they called 'Oumuamua, which means "a messenger from afar arriving first," according to NASA. The reddish object was shaped like a cigar or a pancake, and was over 300 feet long. Its trajectory indicated that it had come from another solar system, traveling through the Milky Way galaxy for hundreds of millions of years before encountering our sun.
