The 365 Days of Astronomy

• Actual Astronomy - Featuring Constellation Taurus

  Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. [email protected] 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.   We also read a few listener emails and answer a question about observing in the snow! - Dan from Switzerland: Dear Chris! Thanks for the compliment on my lunar sketch! - Question from Corey: After having a conversation with a colleague, an interesting question came up: how does snow affect the sky quality? Does the extra albeido of the white landscape bump up the bortle scale a notch or two?   Please subscribe and share the show with other stargazers you know and send us show ideas, observations and questions to [email protected]   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

• Guide To Space - Oldest Rock From Earth Was Found On The Moon (Of All Places)

  https://www.youtube.com/watch?v=0h_ckjhGdjs 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.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

• Astronomy Cast Ep. 763: Interstellar Comets

  https://www.youtube.com/watch?v=op5hkKFWFlM 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 support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

• Travelers in the Night Eps. 331E & 332E: Asteroid Defense & Another Close One

  Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org 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 populated area it could have caused a million casualties.    - Asteroid hunters have become aware of the many small space rocks which come near Earth because of improvements made to telescopes, cameras, and computer analysis software. Recently, my Catalina Sky Survey teammate Rose Matheny used her skills and a new camera to discover the second small space rock in 32 days which came between the communications satellites and the Earth's surface.    We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
