Our coverage of last week’s AAS meeting continues with new work on the formation of planetary nebula based on Hubble Space Telescope images. Plus, a massive quasar in the early universe, water ice on Ganymede, a super-puff planet, and plans for taking spectra of Venus’ surface, featuring our guest, PSI scientist Dr. Darby Dyer.

Rocky Planet Found Orbiting Extremely Old Milky Way Star

Scientists using Hubble to track storms on Neptune found that a current storm has reversed direction and possibly shed a fragment. Plus, an update on Hayabusa2’s sample return, a non-technological radio emission from an exoplanet, This Week in Sky Watching, and more!

Strange Exoplanet Could Be Similar to Theoretical Planet 9

HD 106906 b is an exoplanet 336 light-years away, 11 times the size of Jupiter, and possibly an analog of our own not-yet-discovered Planet 9. Plus, a large body of water ice has been discovered on Mars, and we interview lead author Dan Berman of the Planetary Science Institute. Also included, stories on Jupiter, Uranus’s moons, a young galaxy, and how space weather impacts habitability.

Finding Primordial Ripples Using Gravitational Waves
