H’ad Astra Historia Ep. 201 – The 2025 HAD Osterbrock Book Prize
Today’s guest is Dr. Seb Falk is the recipient of HAD’s 2025 Osterbrock Prize for his book “The Light Ages: the Surprising Story of Medieval Science”. His exceptionally well-written book takes the reader on a learning journey with the 14th century Benedictine monk John Westwyk who, at the end of his career in 1392, wrote an instructional manuscript in Middle English for an equatorie to compute a planet’s location. Originally discovered in 1951 and attributed to Chaucer, 30 years later the manuscript’s author was identified as Westwyk. Based on years of meticulous scholarly research, Falk teaches the reader detailed, and progressively complicated, 14th century science in this thoroughly pleasurable story about Westwyk’s life. 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. Podcaster: Loretta Cannon (an AAS affiliate via Rose City Astronomers) is a science-and-word-nerd who really likes the stars. She quite enjoys working as HAD’s podcaster, bringing astronomy stories to you. We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

Astronomy Cast Ep. 740: Sneaky Stars!
https://www.youtube.com/watch?v=5H24hCeBsNI Streamed live on Jan 13, 2025. Why stars can’t be trusted! If you’re an astronomer you depend on accurate observations of stars, but there’s a problem. Stars are sneaky! Changing in size, brightness, color, they hide their chemistry, their age and even their companions from all but the cleverest observers. Stars explode precisely when they intend to. Betelgeuse took a brightness plunge, T CrB refused to go nova, and other failures to be predictable irk observers for good reasons. Let's talk about it.

From August 4, 2020. Join us today as we talk about newly released research that suggests the waters on ancient Mars were subglacial and not free-flowing. Also, a black hole goes dormant and star formation goes wild. Meanwhile, computer models show that unequal neutron stars colliding may cause a big “bang” that can be detected on Earth.
