'Oumuamua: the first interstellar object found in our Solar System
On 19 October the Pan-STARRS telescope, one of the NASA-funded surveys dedicated to discovering new NEOs, found an object that proved to be extremely unique: for the first time, an asteroid originated around another star had been spotted when transiting inside our Solar System. The object, first labelled P10Ee5V by the discovery team, was quickly followed up by a few observatories, including by our team using the ESA Optical Ground Station in Tenerife.
