The 365 Days of Astronomy Podcast is a project that is publishing one podcast per day, 5 to 10 minutes in duration, for all 365 days of the year. The podcast episodes are written, recorded and produced by people around the world. We are looking for individuals, schools, companies and clubs to provide 5 - 10 minutes of audio for the daily podcast. You can do as few as 1 episode or up to 12 episodes (one per month, subject to our editorial discretion). Our goal is to encourage people to sign up for a particular day (or days) of the year.

Guide To Space - Why Is The Moon’s South Pole So Important?
Last Tuesday at 11:00 AM

https://www.youtube.com/watch?v=q2c7nZB-040

As NASA prepares to return to the Moon by 2024 as part of its Artemis program, the agency is focusing its efforts on exploring the Moon’s polar regions. These are areas of the Moon which seem to have a lot of water mixed in with the regolith.

 

Some of these craters are permanently in shadow, and might still have large quantities of water, that’s accessible to human and robotic explorers. This is a critical resource, and the Moon might be just the place to he...


Astronomy Cast Ep. 193 - Astronomy With The Unaided Eye
Last Monday at 11:00 AM

http://www.astronomycast.com/archive/

From June 7th, 2010.

We talk a lot about telescopes here on Astronomy Cast, but you really don’t need any special equipment to appreciate what the night sky has to offer. Just head outside with some sky charts, maybe a planisphere, some friends and hot chocolate, and you’re good to go. Let’s talk about what kinds of things you can see with just your eyes.

NOIRLab - NOIRLab Education Programs Go Virtual
Last Saturday at 11:00 AM

NOIRLab has a wide variety of educational programs at all sites. Two of the large flagship programs took place in March: Journey Through the Universe at Gemini Observatory in Hawai’I and AstroDay Chile in La Serena, Chile. Both programs are traditionally done in person. In 2021, however, both programs had to adapt and become virtual events. Learn about this programs and how they changed in 2021 and hear what the future may hold!

Welcome to Observing With Webb, where a high school astronomy teacher tells you what you’re looking at, why it’s so cool, and what you should check out later this month…at night. 

April of 2021 delivers a few mornings and a few evenings of lunar close encounters, as well as a meteor shower, as we stay up later to get those dark skies.

April 22nd – LYRID METEOR SHOWER – 2021 is a decent year for the Lyrids, if you’re willing to get up in the morning to watch. At only 10-20 meteors per hour, it is a minor sh...

Cheap Astronomy - Dear CA #65: Unusual Orbits
03/31/2021

Stumbling Around in the Dark Again.

- How do stars in the galaxy orbit?

There is something weird about how stars orbit in the Milky Way Galaxy – and probably in any other rotating galaxy. But the physics of it is totally different to how things work in, say, our Solar System.

- Why doesn’t the image of the black hole in M87 look like the image of the black hole in the movie Interstellar?

So the back story here is that astronomers recently imaged the supermassive black hole within the elli...

Cheap Astronomy - Famous Physics Formulas #7: Free Fall To A Center Of Mass
03/23/2021

Falling, as little as possible.

Free-fall time to a centre of mass

A listener asked the question “How long would it take an object to fall into the Sun from one light year away”. The answer to this question turns out to be a Fantastic Physics Formula, which has been attributed to Arthur C Clarke (who also had geostationary orbits attributed to him). In reality, it could just as well be attributed to Johannes Kepler, since it’s really about the mathematics of an orbital system and the relationship between the distance of an object from t...
