Interstellar comets, coming in and going out - Roger O'Brien
Join us for a captivating journey beyond the boundaries of our Solar System as we explore the mysterious world of interstellar comets. These rare cosmic visitors arrive from distant stars, sweep through our neighbourhood, and disappear back into deep space — leaving scientists racing to study them before they vanish forever. Discover how astronomers detect these fleeting objects, what makes them so unusual, and why each one offers a priceless glimpse into other planetary systems. A fascinating and unmissable talk for anyone who loves the thrill of discovery.
After six decades, Roger O’Brien is still an amateur astronomer. Whilst working for 26 years in a bank in the City, he “survived” to earn a BSc in Astronomy and began teaching.
One course was held at the Sele School and it was students from that course, who founded the Hertford Astronomy Group.
He says that one of his proudest moments was to be elected President of HAG.
