Actual Astronomy - Featuring Constellation Taurus
The 365 Days of Astronomy
Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. Episode 500! The Actual Astronomy Podcast presents Constellation Taurus. In this episode Chris and Shane celebrate their 500th episode by exploring all the nebulae and star clusters in Taurus. Taurus the Bull charges, head down toward Orion. The unmistakable V-shaped pattern marks the Hyades, catalogued as Melotte 25; this is the nearest open cluster at 153 light-years. First-magnitude Aldebaran burns red as the eye of the bull, but it is an accidental member being almost three times closer....

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,...

Today's 2 topics:
- On consecutive nights my Catalina Sky Survey teammate Richard Kowalski discovered two very close approaching asteroids. One of Richard's discoveries, 2016 BY14 must be made out of pretty tough stuff since when it was closest to the Sun it received more than twice the solar energy which heats the surface of Mercury to 800 F. Asteroid hunter's continue to need to track 2016 BY14 to make sure that its orbit does not change to make it a threat as it passes near the paths of Mercury, Venus, Earth, our Moon, Mars, and Jupiter.
- In 2013 my Catalina Sky Survey teammate Steve Larson discovered a space rock streaking through the night sky. For the next 3 days this object was observed by telescopes in California, England, Chile, and New Mexico and given the name 2013 TX68. About 10 days after being discovered, this small asteroid became invisible to human telescopes as it moved towards the Sun with increasing amounts of its dark side facing towards us. Hopefully asteroid hunters will come across 2013 TX68 during its 2016 encounter with Earth. The data obtained will allow us to predict when and how close it will approach our to home planet in future years.
