From December 22, 2008. With Christmas here today, we thought we’d investigate a mystery that has puzzled historians for hundreds of years. In the bible, the birth of Jesus was announced by a bright star in the sky that led the three wise men to his birthplace. What are some possible astronomical objects that might look like such a bright star in the sky? And were there any unusual events that happened at that time?   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. 120: The Christmas Star

The 365 Days of Astronomy podcast launched in 2009 as part of the International Year of Astronomy. This community podcast continues to bring you day after day of content across the years. Everyday, a new voice, helping you see the universe we share in a new way. This show is managed by Avivah Yamani, edited by Richard Drumm. This podcast is funded through Patreon.com/CosmoQuestX and produced out of the Planetary Science Institute.

Astronomy

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 Today's 2 topics: - C/2016 Q4 (Kowalski) is my Catalina Sky Survey teammate Richard Kowalski's 14th comet discovery. It orbits the Sun once every 68 years on a cold path between Saturn and Neptune. - I knew from the short regularly space streaks on the four images I had just obtained with the Catalina Sky Survey's 60 inch on Mount Lemmon, Arizona, I was looking at the path of an Earth approaching object. Turns out, this previously unknown object, is an unusual Aten astrtoid in that its orbit is inclined 38 degrees to the path of the Earth around the Sun. It's high relative speed is caused by the fact that our paths intersect at a large angle making it similar to two vehicles coming together on intersecting highways.   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. 275E & 276E: Strange Comet & Screaming Aten

I’m Rob Webb, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare.  This month, I’m recording on the go!  I’m traveling and recording on a different laptop than normal, with a microphone from 2012, and less than 6 hours of sleep each night this week. I’ll treat this as a…learning opportunity…   As usual, we’ll start by talking about where the naked eye planets are this month, move on to the lunar phases, and finish up with a calendar of events, so you can plan ahead better than me. June brings us the quote “Parade of Planets”...well, sort of…Listen up as I discuss which planets are visible, which aren’t, and when the Moon will pass by them.   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!

Last Minute Astronomer - June Episode

From May 22, 2024. In this episode, we’re taking a closer look at Sunspot complex 3664 and the beautiful chaos that it’s been creating. And because we’re in a planetary science kind of mood, we’re also looking at stories related to observing weather on alien worlds, the history of Mars Climate, and even how solar storms might affect that particular Red Planet.   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!

EVSN - Carrington 2024

Hosted by Loretta Cannon for the AAS-HAD. Today’s guest: Dr. Steve Maran (retired from NASA and AAS - https://aas.org/stephen-p-maran) shares stories with us from his almost 70 years working, and having fun, in astronomy.   H’ad astra historia is the official podcast for the Historical Astronomy Division of the American Astronomical Society.  We’re here to share stories from and about the people who study the stars, planets, and the cosmos.  We’ll be hearing from individuals who not only study the history of astronomy, but also those who lived it, who were “in the room” during pivotal events within the last 50 years or so.     podcast music: "Frost Waltz" Kevin MacLeod (incompetech.com), licensed under creative commons: by attribution 4.0 license (http://creativecommons.org/licenses/by/4.0/)   Bio: Loretta Cannon, an AAS affiliate via Rose City Astronomers, is a member of the leadership committee for the Historical Astronomy Division (2023-2025). She is a polymath with degrees in anthropology, microbiology & biochemistry, and has many years of experience in both the private sector and government. When not reading some of her way-too-many books, she watches BritBox, creates recipes, or plays in the garden. She chose science writing/editing in astronomy as a new career. In short, she’s a science-and-word-nerd-foodie-with-a-plant-habit who really likes the stars.   Steve Maran’s Dec 2023 article for HAD’s This Month in Astronomical History, “Comet Kohoutek, Skylab, and More”:   https://aas.org/posts/news/2023/12/month-astronomical-history-december-2023   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!

H’ad Astra Historia - Ep 103: A Distinguished Career

Hosted by Steve Nerlich. What can the anti-matter be? Dear Cheap Astronomy – How much antimatter is there and will it eventually annihilate? Antimatter is generally found in subatomic particle form – so there’s antiprotons and anti- electrons, which can rarely come to together to form an antihydrogen atom. But that’s about it, an anti-helium nucleus has been created in a laboratory but neither it nor any other more complex anti-nuclei have been observed in nature.   Dear Cheap Astronomy – How fast could we get to Alpha Centauri with current technologies? If we calculate the trip duration based on speeds achievable with current technology, a mission to Alpha Centauri, the nearest star system to ours, would take over 6,000 years. But even that is wildly optimistic when you consider the mass you need to accelerate up to those speeds.   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!
