Universe Today podcasts with Fraser Cain

The Guide to Space is a series of space and astronomy poddcasts by Fraser Cain, publisher of Universe Today

00:00 Start
00:12 Would extraterrestrial life have any impact on us?
03:01 When did Mars shut down?
05:16 Could the rovers be repaired?
07:05 Would an ejected star take its planets with it?
08:54 Dangerous to go to Mars at the same time?
10:19 Is there any way to go faster?
13:37 Should the smallest black holes already have evaporated?
15:48 Shouldn't Voyager be coming back?
17:15 Could there be life inside Jupiter?
18:50 Does the Sun have a binary black hole partner?
19:57 Aren't I on vacation?
