Customer Reviews
Better than StarTalk
I love the show gets a deal strictly with Astronomy and not some stupid comedians and everything else sports StarTalk used to be great but now it’s going downhill fast.Fraser is a great host and I love the show and astronomy podcastWith cohost Pamela Gray
Has Taken Over StarTalk
Like I have seen with some people here, I have moved here from StarTalk which has been gradually becoming more comedic. They have started to run out of ideas and don’t know how to deal with it. So far, with this podcast, I have not seen any of that loss of idea. Always has something to talk about and always goes into great depth. Love it!
Long Time Follower of Universe Today
The host is well-known in astronomy and science circles— Mr. Fraser Cain smartly hosts a ‘multi-media pronged’ endeavor that gives astronomy a sense of popularity and a new sense of purpose. Not since Carl Sagan— can I think of someone who has elevated science to a sense of purpose that many of us could follow as a template. Take you Fraser!
