Hunting for exoplanets – planets around stars other than the Sun – is a booming astronomical industry. Results from facilities all over the world, particularly from NASA’s Kepler satellite, have shown that planets are common, and given new insight into the formation of our own Solar System. The latest planet hunting satellite, TESS, provides a chance to find planets around brighter stars In this talk, Chris Lintott (University of Oxford, and presenter on BBC Sky at Night) will talk about what we know and don’t know about how planets form and will explain how you might find a planet of your own using only a laptop. There will be at least one photo of penguins, and some speculation about alien megastructures.
