Episode 177: The Case of the Missing Dark Matter, with Guo Chi

Feature Guest: Guo Qi Dark matter vastly overshadows ordinary matter in our universe. Wherever astronomers turn their telescopes they find galaxies dominated by dark matter. But all that changed recently with the first discoveries of dwarf galaxies suspiciously deficient in dark matter. To make sense of this baffling finding and how it relates to our Milky Way's own local dwarf galaxies, today we're joined here at The Star Spot by study lead Professor Guo Qi from the Chinese Academy of Science. Current in Space NASA's newest planet hunter has made its most remarkable discovery yet: an Earth-sized world in its star's habitable zone, and Anshool provides everything you need to know. Amelia and Priyanka explain a mystery surrounding a particle, and a strange halo around a pulsar may be the key to solving it. And in his debut, Jeff offers more pulsar news in that a new surface map of a particular pulsar may question everything we thought we knew about these lighthouses of the Galaxy. About Our Guest Guo Qi is Professor of Astronomy at the National Astronomical Observatories of the Chinese Academy of Science. She received her PhD from the Max-Planck Institute for Astrophysics and held a Postdoctoral Fellowship at the UK's Durham University.
