What listeners say

A curated, balanced selection of Apple Podcasts reviews.

I have listened to several different astronomy podcasts over the years. This one is far and away the best. It is the only one I make sure never to miss. Although Mr. Gary is apparently a scientific layman, the depth and breadth of his knowlege of astronomy, and space science are truly impressive. He obviously does not read just the popular literature. He on top of the important professional journals. This enables him to ask wonderfully insightful questions in his interviews of practicing scientists. I also enjoy his condensed audio feeds from space launches. I could go on and on, but I won't bore you. If you are interested in astronomy, listen to a couple of episodes of SpaceTime. You will be hooked.

Beavertonian · May 2016

My wife and I have been long time listeners to this podcast. We were so incredibly sad when it was briefly cancelled by ABC (Australia). It is a great podcast for those interested in astronomy and space exploration. We appreciate that the topics are covered in greater detail than most news shows give these topics, and Stuart Gary does a great job lining up interviews with real experts on the topics.

Star Stuff is my favorite astronomy podcast despite some tough competition. Great interviews and Stuart is a pro at distilling the most interesting astronomy news. Glad to have the show back.

publiusjones · Feb 2016

I have been listening to Star Stuff for years; I listen to the day it comes downloaded. It’s a wrap up news from the Astronomical world from the last few days. It is fast-paced, informative and full of detailed interviews with experts who know their Star Stuff. This current incarnation gives us TWO episodes each. Often he tells me about Star Stuff that happened at Cape Canaveral, only 180 miles from my house, that I wouldn’t otherwise have known. I don’t know how Stuart keeps up with all this Star Stuff - He must have a staff of a hundred ears and eyes, listening and watching. If you care about Star Stuff, this will fill your ears!
