The presence of an unidentified object hurtling through our solar system recently prompted a call to action from observatories throughout the world. NASA has confirmed that it’s the first object to arrive from another star – and it may be as long as a quarter mile. While the rocky asteroid, dubbed ‘Oumuamua, is definitely not piloted by aliens, it could give us clues into the formation of other solar systems. In late October, scientists thought they might have observed an object that came from outside the solar system with the aid of the University of Hawaii’s Pan-STARRS1 telescope.
