ESOcast 26 Jun 2020, 08:47 UTC In this ESOcast, we explore some of the many questions interstellar visitors 1I/'Oumuamua and 2I/Borisov have raised including: what are they made of? How did they form? Are they like the comets or asteroids in our Solar System? And finally, what can they reveal about other planetary systems? Image credit: ESO/ M. Kornmesser.
