Guide To Space - Oldest Rock From Earth Was Found On The Moon (Of All Places)
The 365 Days of Astronomy
From Feb 2, 2019. Geologists think they’ve found the oldest Earth rock ever seen. And they found it in one of the last places you’d ever suspect, on the Moon. When the Apollo 14 astronauts returned their lunar samples back to Earth, they were carrying one rock that had formed on Earth 4 to 4.1 billion years ago, which was carved out of our planet during the time of intense bombardment and delivered to the Moon.

Astronomy Cast Ep. 763: Interstellar Comets
The 365 Days of Astronomy
Season 19. Streamed live Sep 8, 2025. Welcome to the first episode of our 19th season! This week we look at objects coming from other solar systems that come passing on by our Sun. During the summer hiatus the 3rd interstellar object was discovered: Comet 3I/ATLAS! So now we have 3 different interstellar interlopers to compare & contrast. What are we starting to learn about other star systems from this small sample size and how will our detection get even better? [Editor’s note: HiRISE’s telescope is 1/2 meter.] We've added a new way to donate to 365 Days of Astronomy to...

Travelers in the Night Eps. 331E & 332E: Asteroid Defense & Another Close One
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 April 2025. Today's 2 topics: - In 2013 a 56 foot diameter space rock exploded over Chelyabinsk, Russia releasing the energy of 450 kilotons of TNT and filled local hospitals with some of the 1,500 people who were injured. Fortunately no one died. In 1908 a 200 ft diameter meteor exploded over a largely unpopulated region at Tunguska, Siberia knocking down trees over a 750 square mile area. If it had hit over a...

NOIR Lab - Fast X-Ray Transients & The Deaths Of Massive Stars
The 365 Days of Astronomy
Since their first detection, powerful bursts of X-rays from distant galaxies, known as fast X-ray transients (FXTs), have mystified astronomers. FXTs have historically been elusive events, occurring at vast distances away from Earth and only lasting seconds to hours. Einstein Probe (EP), launched in 2024, is dedicated to observing transient events in the X-ray and is changing the game for astronomers looking to understand the origin of these exotic events. In this podcast, Dr. Robert Eyles-Ferris discusses a recent FXT and what it reveals about the deaths of massive stars. ...

EVSN - Rockets Make Bad Neighbors
The 365 Days of Astronomy
From September 3, 2025. In this week's episode, we take a look at the impact SpaceX launches from the Space Coast will have on their competitors and those living, working, and going to school near Kennedy and Cape Canaveral. We also look at a bunch of new science discoveries, including the origins of Ryugu & Bennu, the solar system shocked itself, a new supernova that blew off an unusual number of layers before exploding, and quick updates on Psyche, Juno, JUICE, and the number of moons orbiting Uranus.

Space Stories - Where Day Meets Night: The Equinox
The 365 Days of Astronomy
Hosted by Avivah Yamani, our Director. We are exploring the word Equinox. We start by having the definitions, why “equal night” isn’t quite exact, how spring/autumn flip between hemispheres, and a whirlwind tour of equator monuments from Pontianak to Macapá, Cayambe, Kayabwe, Nanyuki, Ilhéu das Rolas, and Bonjol.

Guide To Space - What Does the Universe Do When We're Not Looking?
The 365 Days of Astronomy
Hosted by Fraser Cain. From Jul 19, 2016. Some of the greatest discoveries in astronomy have been made by watching how the skies change over time. Today we talk about these techniques, and an observatory that will revolutionize time-based astronomy.

Ask A Spaceman Ep. 255: How Do The Biggest Stars Get So Big?
The 365 Days of Astronomy
How do we measure the sizes of stars? What are the biggest ones today, and how big could stars have gotten in the past? Is there any way for a star to cheat and get even bigger? I discuss these questions and more in today’s Ask a Spaceman! Support the show: All episodes: Watch on YouTube: Read a book: Keep those questions about space, science, astronomy, astrophysics, physics, and cosmology coming to #AskASpaceman for COMPLETE KNOWLEDGE OF TIME AND SPACE! Big thanks to my top Patreon supporters this month: Justin G, Chris L, Alberto M, Duncan M, Corey D, Michael P,...

Astronomy Cast Ep. 155: Dwarf Stars
The 365 Days of Astronomy
From September 14, 2009. We think we live near an average star, but that’s not the case at all. Compared to most stars in the Universe, the Sun is a giant! Let’s look at the small end of the stellar spectrum, to stars with a fraction of the size and mass of our own Sun. There are many ways that a star can get small, and they lead dramatically different lives and deaths.

info_outlinePaul Hill, Ralph Wilkins and Dr. Jenifer “Dr. Dust” Millard host.
Damien Phillips, John Wildridge and Dustin Ruoff produce.
The Discussion:
- Farewell Frank Drake.
- It’s uncrewed, not unmanned!
- Filming with the BBC again.
- Listeners’ emails on city astronomy and the missing AweAst show this month.
The News:
- JWST unearths a huge cosmic riddle: CEERS-1749!
- Artemis 1 moon launch delays.
- Solar astronomers solve one of the great mysteries about the Sun.
- A round up of all the incredible things that have happened in space this month.(Thanks to @jessicaxlis for the inspiration… and much of the content!)
Skyguide:
As we’re a little late in the month for a September skyguide, this is a quick guide to the astronomy events to observe over the next few months. Pay attention because there’s some great oppositions, occultations, eclipses, meteor showers and possibly even a couple of naked eye comets!
Q&A:
Can red-shift, spectroscopy, mass evaluations etc still be counted on even after the images have been distorted & magnified by foreground galaxies? Can the effect of gravitational lensing be accurately accounted for?
From our good friend Alan Beech in the UK.
