‘Oumuamua: The Scout from Interstellar Space
In 2017 our solar system was briefly visited by an object from interstellar space. Observatories around the Earth studied it intensely for the few days it remained detectable by modern instruments. The object was named ‘Oumuamua, which is Hawaiian for ‘scout’, and had unusual characteristics. While most astronomers have concluded that the interstellar object was likely made of rock and ices (e.g., asteroid; comet), a prominent astrophysicist at Harvard University, Professor Avi Loeb, has argued that the object may be an ancient spacecraft launched by another civilization in our Milky Way galaxy. The concept of space archaeology has emerged. This presentation will describe the observational data about this interstellar visitor known as ‘Oumuamua.
