An Interstellar Visitor from Deep Space
Sometime around the year 1837, a mysterious object silently crossed an invisible cosmic milestone: 1,000 astronomical units (AU) from the Sun, where one AU represents the average Earth-Sun distance. It then continued its journey toward our star.
The Historic Discovery on October 19, 2017
Traveling undetected toward the Sun for more than a century, the object finally caught human attention. On the night of October 19, 2017, astronomers observed a faint and thin celestial body that was later named 'Oumuamua.
Scientific Impact of the Interstellar Discovery
The discovery of 'Oumuamua marked a significant milestone in detecting objects arriving from outside our Solar System. Observing this unique cosmic visitor opened new perspectives in astronomical research.
