Walkabout the Galaxy

A system of seven Earth-sized planets has been observed orbiting a (relatively) nearby star. At least three of these planets are in the habitable zone, or as Top Astroquark Jim Cooney would say, the haBITable zone. That's where there may be liquid water on the surface of the planet. The star for these planets is tiny and not so hot, so the planets are huddled around it like campers around the embers of a dying fire. Tune it for that plus: Star Wars! Note to Star Wars and Star Trek: next movie have some planets that are, like these, so close to their star that they have synchronous rotation, with a permanent dayside and a permanent nightside!

It's the plural episode of Walkabout as the Astroquarkae discuss the formation of White Dwarfs and Planetary Nebulae, what they have to do with each other, planets, and the price of tea in China (answers: lots, something superficial, and nothing at all). Also in this episode: nerd news, fishing advice, space trivia, and an imperial sponsor. 

Walkabout the Galaxy is a fun and informative discussion of news in astronomy hosted by astronomers Josh Colwell, Addie Dove and Jim Cooney.

The astroquarks welcome Brendan Byrne from WMFE 90.7 to discuss the some jaw-dropping images of Saturn's rings as Cassini begins working its way in towards its fateful plunge into Saturn on September 15, 2017. Along the way we'll dissect F/X no-no's in Star Wars and find out from Brendan if we're there yet. There = Mars, by the way, and time's a wastin'.
