Astronomy Cast Ep. 17: Where Does the Moon Come From?
The 365 Days of Astronomy
From January 1, 2007. We take the Moon for granted, but its effect on the Earth is very important; possibly even critical for the formation of life. But where did it come from? Did the Earth and Moon form together? Or did the Earth capture a wayward Moon? Or was there a more catastrophic cause to this lunar mystery?

The Cosmic Savannah - Ep. 64: Bursts From Space
The 365 Days of Astronomy
In this episode, Tshiamiso and Dan have a discussion with Alexander Andersson from Oxford University about Zooniverse, citizen science projects and how citizens can contribute to the work that astronomers do. During the episode Alex discusses how important and useful the work done by participants in the Bursts from Space project is for helping scientists train AI in the search for radio transients – or as Alex puts it: “Things that go bump in the night”. Join us for another exciting episode and learn how you can contribute to the fascinating research going on in Astronomy today!...

EVSN - Impact Gardening Churns Surface of Saturn’s Moon Europa
The 365 Days of Astronomy
From July 17, 2021. Over tens of millions of years, the surface of Europa has been churned by impacts down to an average depth of 30 centimeters. This churning means that the search for chemical biosignatures must look below that zone. Plus, methane and icequakes at Enceladus, predicting underwater eruptions, Virgin Galactic's flight, and a Chinese spacewalk.

The 365 Days of Astronomy
From September 6, 2023. Hosted by Tony Darnell. Astronomers have recently concluded an observation study of the closest exoplanet to Earth, Proxima Centauri b and found that the planet does not transit its star. These observations settle a question that astronomers have been asking since the exoplanet's discovery in 2016 using the radial velocity method.

Cheap Astronomy - Dear CA # 113: The Planets
The 365 Days of Astronomy
We’ve plundered Earth, what’s next? Dear Cheap Astronomy – If we did colonize the Solar System, what would we do with the different planets? It remains to be seen if we will spread out across the solar system. While we starting to feel more confident about avoiding a mass extinction asteroid strike, a super-volcano eruption could just as easily end civilization as we know it. There’s also the more mundane scenario of where our population keeps growing, we run low on resources and then fight a bunch of wars over what’s left, pretty-much trashing what’s left of the ecosystem in the...
