Walkabout the Galaxy closes out 2019, the first annual Year of the Astroquark, with an episode touching on everything from interstellar comet I2/Borisov to the tiger stripes of Enceladus and the first map of the surface of a freakin' neutron star! As always we share abundant space news, from Starliner to the Mars InSight mole, and embarrassing nerdiness, so wrap up the year with Strange, Charm, and Top, and we'll see you in 2020 for the second annual Year of the Astroquark.
