Is it Aliens? The Most Unusual Star in the Galaxy - Chris Lintott

Boyajian's star, a faint and unprepossessing presence in the constellation of Cygnus, attracted astronomers' attention when it began to flicker alarmingly. We will discuss explanations for its behaviour, from disintegrating comets to alien megastructures, and consider how modern astronomy hunts for the truly unusual objects in the Universe. For this task, the involvement of large numbers of volunteers - citizen scientists - is essential, for example via the Zooniverse platform, which invites you to participate in classifying galaxies and discovering planets. This lecture was recorded by Chris Lintott on 29th April 2024 at Conway Hall, London Chris is Gresham Professor of Astronomy. He is also a Professor of Astrophysics at the University of Oxford, and a Research Fellow at New College.
