Astronomers Search for Clues of Alien Life on “Oumuamua”

The thought that Earth might not be the only planet that harbors life is an inevitable one. Possibilities of extraterrestrial life in the vast expanse of the universe are arguably limitless. In their quest for evidence of alien life, astronomers are turning their attention to an interstellar object that is known to be traveling though our solar system. This object could be either a comet or an asteroid. Since the time we shared news about its discovery, it has earned the name of “Oumuamua” which ideally means “scout”. Oumuamua has a unique “cigar” shape that somehow indicates that it could have potentially been artificially shaped by aliens for space aerodynamical travel purposes. For this reason, a team of astronomers from the Search for Extraterrestrial Intelligence (SETI) institute are working on a program called Breakthrough Listen using the Green Bank Telescope to closely observe Oumuamua across radio bands for any kind of observable evidence of extraterrestrial life.
