    Ask A Spaceman Ep. 273: What if the Universe Had No Beginning?

    Hosted by Dr. Paul M. Sutter. What does is mean for the Universe to have a wave function? How does Hawking's "no boundary" proposal mean that the Universe comes from itself? And is it really the final answer?

    Travelers in the Night Eps. 885 & 886: Dark Sky Network & Aviation and Space Weather

    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 February 2026. Today's 2 topics: - Around the world those who value the natural night sky are evaluating the effects of light pollution. In addition to impairing astronomy and star gazing the past 100 years of increasing light pollution is proving to be harmful to human health and the natural world upon which we all depend. The purpose of the Dark Sky Network is monitor and facilitate the mitigation of the harmful effects of light pollution.   - The Earth's atmosphere does a good job of protecting humanity from space weather, however, occasionally a major event does break through our shield and gets our attention. Tree rings and ice cores have recorded past space weather events thousands of time larger than which have occurred in the modern age. Investing in research seems wise.   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!

    UNAWE Space Scoop - Story Of the Sun's 'Road Trip' Through the Milky Way With Friends

    https://spacescoop.org/en/scoops/2605/story-of-suns-road-trip-through-the-milky-way-with-friends/ Did you know that our Sun and its many, uh, childhood friends were all born at a place much closer to the center of our Galaxy? Over the years, our Sun and its friends have been on sort of a speedy galactic tour traveling a distance of almost 10,000 light-years from the center of the Milky Way. But traveling much farther than that on a long curved trajectory! Astronomers call this the 'mass migration' of stars. Kind of like a flock of migrating birds.    How and when did these stellar siblings migrate to where they are now? To find out, a team of astronomers did some galactic archaeology, tracing the history of stars in our Galaxy. Using data from ESA's Gaia telescope, the team found almost 6,600 stars just like our Sun. The astronomers aptly call these stars the 'solar twins.'    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. 303: A Review of This Month in Astronomical History

    Today's 'guest' is HAD's This Month in Astronomical History. I'll be reading two essays from the archives: Dr. Rebecca Charbonneau's Aug 2018 essay titled, "The Mysterious Wow! Signal" and Dr. Richard Fienberg's May 2022 essay titled, "The First Telescope on the Moon." This Month in Astronomical History is a lead-in to next month's interview with the new Editor, Dr. Mugdha Polimera.   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 theme music: "Frost Waltz" Kevin MacLeod (incompetech.com), licensed under creative commons: by attribution 4.0 license (http://creativecommons.org/licenses/by/4.0/)    Podcaster:  Loretta Cannon (an AAS affiliate via Rose City Astronomers) is a science-and-word-nerd who really likes outer space and the people who study it.  She quite enjoys working as HAD's podcaster, sharing astronomy stories to you.   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!
