The first minor planet from beyond our Solar System was discovered in October 2017. `Oumuamua may have been travelling between the stars for billions of years before its brief visit to us. Michele Banister will take you on a journey from the excitement and uncertainty of the first announcement to the confirmation of `Oumuamua's interstellar origin, and the rapid pace of observations that she and her colleagues made with telescopes around the world to understand this skyscraper-sized visitor: barely a week after discovery, it grew too faint to see.
