Artist’s impression of the interstellar asteroid `Oumuamua

This artist’s impression shows the first interstellar asteroid, `Oumuamua. Observations from ESO’s Very Large Telescope in Chile and other observatories around the world show that this unique object was travelling through space for millions of years before its chance encounter with our star system. It seems to be a dark red highly-elongated metallic or rocky object, about 400 metres long, and is unlike anything normally found in the Solar System.
