(200 words excerpt, click title or image to see full post)

We have a new podcast on the feed! It’s been a while since our last show but we made up for it with a nice, long and informative show about Polaris, also known as The North Star.
The podcast features the usual crew — Michael Koppelman, Doug Welch and Mike Simonsen and includes an interview with Dr. Edward Guinan and Scott Engle from Villanova University.
A quick summary of Polaris facts:

Polaris is not the brightest star in the sky.
Polaris is in the north.
Polaris hasn’t always been and won’t always be the north star.
Polaris is a variable star of a type known as Cepheids, which have been important stars in understanding cosmic distance scales.
