We've been looking forward to sharing this one with you... Last year, we started thinking about what it would take to detect mountains, valleys and volcanoes - surface topography - on an exoplanet. It seemed like a crazy idea at the time but we decided to make the calculation for fun and were surprised that it may actually be feasible in the not too distant future. Moiya McTier of the Cool Worlds Lab explains how we started thinking about this and our novel method for attempting to detect such features. As always, we look forward to answering your questions you may have about our research - Have a great day!
