    Astronomy Cast Ep. 744: Lunar Time

    Astronomy Cast Ep. 744: Lunar Time By Fraser Cain & Dr. Pamela Gay Streamed live on Feb 10, 2025. What time is it? OK, fine, what time is it on the Moon? The Moon orbits the Earth, so it doesn’t fall into a specific time zone. Also, there’s lower gravity on the surface of the Moon, which changes the rate that clocks tick. Well… It’s time to introduce Lunar Time.  When are you when you are on the Moon? Researchers are putting together definitions! Hosted by: Fraser Cain and Dr. Pamela L.

    Astronomy Cast Ep. 741: Technosignatures By Fraser Cain & Dr. Pamela Gay Streamed live on Jan 20, 2025. As humanity developed more advanced technology, we’re having a larger effect on our environment. The more we do, the more we could be detectable.

    Astronomy Cast Ep. 740: Sneaky Stars!

    Astronomy Cast Ep. 740: Sneaky Stars! By Fraser Cain & Dr. Pamela Gay Streamed live on Jan 13, 2025. Why stars can’t be trusted! If you’re an astronomer you depend on accurate observations of stars, but there’s a problem. Stars are sneaky! Changing in size, brightness, color, they hide their chemistry, their age and even their companions from all but the cleverest observers. Stars explode precisely when they intend to. Betelgeuse took a brightness plunge, T CrB refused to go nova, and other failures to be predictable irk observers for good reasons. Let's talk about it.   SUPPORTED BY YOU!
