During the recent AAS meeting, I also managed to catch up with Hannah Wakeford - exoplanet cloud expert. We're just starting to learn about clouds on exoplanets and recent work has found evidence for corondum clouds, a mineral which forms the basis of rubies and sapphires! Hannah explains how this weirdness arises, how we detect them and what other surprises might lie in store for us. Be sure to check out Hannah's podcast (www.exocast.org) for more exoplanet news! ::More about this Video:: ► Wakeford et al.
