Artist’s concept of interstellar object1I\/2017 U1 (‘Oumuamua) as it passed through the solar system after its discovery in October 2017. Image Credit: European Southern Observatory \/ M. Kornmesser<\/p><\/div>\n

The first interstellar object to be discovered was ‘Oumuamua, detected in 2017. Joined by Comet 2I\/Borisov a couple of years later, astronomers are eagerly awaiting further discoveries of such objects, which were ejected from other solar systems.<\/p>\n

We explore what the link is between these interstellar objects and the history of star formation around the galaxy, thanks to new research by Prof Chris Lintott<\/a> (University of Oxford), Dr Ted Mackereth<\/a> (University of Toronto, Canada) and Dr Michele Bannister<\/a> (University of Canterbury, New Zealand).<\/p>\n

Chris and Ted explain how these two seemingly disconnected fields have led to new hypotheses about what we might learn from future observations.<\/p>\n
