Astronomers using the Panoramic Survey Telescope and Rapid Response System (Pan-STARRS 1) telescope in Hawaii uncovered the odd object, which was at first designated as A/2017 U1.
[ ] "It's long been theorized that such objects exist — asteroids or comets moving around between the stars and occasionally passing through our solar system — but this is the first such detection," Paul Chodas, manager of the Center for Near-Earth Object Studies at the NASA's Jet Propulsion Laboratory in Pasadena, California, said .
The visitor was also tumbling end-over-end and had a dark red color, similar to other cold, small objects in the outer solar system.
Observations suggest that it is than our solar system's homegrown comets, perhaps because 'Oumuamua's outgassing has blasted dust from its surface, revealing bright ice underneath.
After seeing 'Oumuamua, researchers are now eager to spot other similar objects.
