The Cosmic Savannah - Ep. 77: Troublesome Inkathazo & the Age of Giants
The 365 Days of Astronomy
Hosted by Dr. Jacinta Delhaize, Dr. Tshiamiso Makwela & Dr. Daniel Cunnama. In this “mid-season special” episode, we introduce you to an extraordinary giant radio galaxy nicknamed “Inkathazo”, meaning ‘trouble’ in isiXhosa and isiZulu. We speak with Kathleen Charlton, a Master’s student from the University of Cape Town, about the discovery of Inkathazo and her newly published work on the topic. Kathleen spoke with us from the University of Oxford, where she was working with team members from the ‘MIGHTEE’ collaboration. She describes her experiences of first...

EVSN - Six-Exoplanet System in Resonance, Challenges Formation Theories
The 365 Days of Astronomy
From January 27, 2021. It’s a day ending in ‘y’, and planetary formation theories are once again being challenged. This time the challenge comes from a six-planet system with five planets in resonance. Plus a cloudless Jupiter, TRAPPIST-1, volcanoes, and some science of the weird.

Space Stories - Second Landing
The 365 Days of Astronomy
Hosted by Dr. Pamela Gay. A gentle fancy for the Christmas Season—an oft-told tale with a wistful twistful of Something that left the Earth with a wing and a prayer. Earlier today, I had the stark realization that at the core of many Christmas stories is a core of sorrow or longing that must somehow be transformed into joy. Scrouge must learn charity. Ralphie longs for a bb gun and is betrayed by his joy. George is on the brink of suicide when his Guardian Angel intercedes. John McClane just needs to keep his wife alive (yes, Die Hard is a Christmas movie). Over and over, the holiday...

Space Stories - Solstice: When the Sun Stands Still
The 365 Days of Astronomy
Hosted by our Director, Avivah Yamani! What does “solstice” really mean? In this episode, we unpack the Sun’s yearly turning point, the seasonal flip between hemispheres, and the ancient sky-architecture of Stonehenge, from June solstice sunrise to December solstice sunset.

Astronomy Cast Ep. 775: The Hydrogen 21-cm Line
The 365 Days of Astronomy
Hosted by: Fraser Cain ( ) and Dr. Pamela L. Gay ( ) Streamed live on Dec 15, 2025. Atomic hydrogen is the raw material for stars, but there’s a problem. It’s cold & dark, but it can do a very rare trick, releasing a photon in a very specific wavelength, known as the 21 centimeter line. And thanks to this wavelength astronomers have mapped out star forming regions across the Milky Way, the Universe and into the Dark Ages! This forbidden transition of Hydrogen has led to the mapping of galaxy rotation, a cool classroom application of quantum mechanics, and weirdly no Nobel prize. In...

Travelers in the Night Eps. 359E & 360E: One in 100,000 & Finding Spacerocks
The 365 Days of Astronomy
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. From October 2025. Today's 2 topics: - Friday the 13th appears to continue to be a lucky day for the human race. When astronomers first discovered Apophis in 2004 it appeared possible that this 3 million ton, 1,200 foot diameter asteroid traveling at 8 mi/s could impact our planet creating a crater a several miles diameter and more than a half mile deep. Additional observations over the years have eliminated this possibility...

EVSN - Asteroid Destruction, Brown Dwarf Formation & Getting Science From Dust
The 365 Days of Astronomy
From February 11, 2020. Today’s show starts with a mighty YORP. It turns out the YORP effect may spin asteroids to death in dying star systems. We also look at how the formations of giant planets and brown dwarf stars differ, and a new way to get science from dust.

Actual Astronomy - PiFinder
The 365 Days of Astronomy
Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. Today we have a guest joining us, Richard Wolf-Jacobson who is the founder of BB Labs/ PiFinder which is a new type of finder device. Before we get going Richard, can you tell us about where you are / observe / how you got started in Astronomy, what your interests are and what equipment you use? * What is a Pi Finder? * How does it work? / How do you set it up? * Do you need to attach anything to your AltAz or Dec Axis? * What is plate solving..isn’t that just for imagers? * How...
info_outlineWhat is gracing the September 2024 skies? A juuuuust barely partial lunar eclipse, the best viewing for Saturn, 5 lunar close encounters, and the transition to fall.
Hi everybody, I’m Rob Webb, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare.
We’ll start by talking about September’s big events, then highlight the naked eye planets, and finish up with the lunar phases, so you can plan ahead better than me.
7th – 8th – Opposition of Saturn – Saturn, Earth, and the Sun are essentially lined up, causing Saturn to rise at sunset, and set at sunrise, with best viewing around midnight.
17th - Just Barely Partial Lunar Eclipse - The Moon passes into the shadow that Earth is casting into the solar system, but only a little. Times here are Eastern Daylight, so adjust for your location, assuming you are in the Americas, Africa, or Europe. The penumbral stage will be almost not noticeable, however the hour of partiality will be. At 10:12pm the Moon will start to graze the dark inner portion of the Earth’s shadow called the umbra. About half an hour later it’ll be at maximum eclipse, with 8% of it covered up. Another half hour later, the dark shadow will no longer be noticeable, and the moon will be in the penumbra until 12:47am.
8:41pm - Penumbral Eclipse Starts
10:12pm - Partiality Starts
10:44pm - Maximum Eclipse (8%)
11:15pm - Partiality Ends
12:47pm - Penumbral Eclipse Ends
