Kepler's Dark Worlds | Tiffany Jansen @CoolWorldsLab

Cool Worlds | Kepler's Dark Worlds | Tiffany Jansen @CoolWorldsLab | Uploaded 6 years ago | Updated 4 hours ago
Graduate student Tiffany Jansen recently submitted a new paper making the first-ever measurement of the reflectivity, or "albedo", of small exoplanets discovered by Kepler. In this video, Tiffany explains how we pulled off this trick by stacking different but similar planets together to boost signal-to-noise and showing for the first time that even sub-Neptune sized planets tend to be dark. Make sure to say congratulations to Tiffany and Moiya below who recently were awarded a prestiguous NSF fellowship for their excellent research!

$The Jovoscope Planets, like the Earth, could potentially serve as giant telescopes - as explored in our last video (https://youtu.be/jgOTZe07eHA). This happens because the atmosphere refracts light and so bends it into a focus, like a huge spherical lens. Parabolic dishes on Earth can be sued as both telescopes and antennae, and so in the same way - could planets be used as antennae? Today we explore the possibility of using the Jupiter as a giant antennae, perhaps serving as the basis for an interplanetary internet, and how Juno could very well test the idea today.
