Awesome Astronomy - Have Blue Origin Already Lost to SpaceX?
The 365 Days of Astronomy
Ralph Wilkins hosts. Damien Phillips, John Wildridge and Dustin Ruoff produce. From Aug 5, 2022. Blue Origin rocket developments seem to have been in development for decades. They've only just got their sub-orbital New Shepard rocket launching and, even now, they aren't launching that often. Their orbital New Glenn rocket keeps getting delayed and might even be obsolete to SpaceX rockets if it ever delivers. With Elon Musk's SpaceX leading the way in commercial spaceflight and Branson's Virgin Galactic offering an alternative, has Jeff Bezos merely spent a lot of money on...

Cheap Astronomy - Fantastic Physics Formulas, Episode 10
The 365 Days of Astronomy
Blowing off some steam. Read by Barry Haworth and Duranee, written by Steve Nerlich, with technical advice from Stephen D'Souza. - The orbit equation: There are several orbit equations around, but this orbit equation tells you what orbital velocity you need to maintain an orbit at a particular altitude. - Entropy and the Inequality of Clausius: Getting to this formula requires a bit of a story, but it’s worth it as it ends up explaining which direction the Universe is moving in. The conversion of heat, a form of energy, into work dates back to ancient Roman times, although heat...

Exoplanet Radio - Ep. 22: HAT-P-67b: The Largest Known Exoplanet
The 365 Days of Astronomy
From August 17, 2023. According to the NASA exoplanet archive, HAT-P-67 b holds the distinction of being the largest exoplanet in terms of size. With exoplanet classification, one always needs to be careful - especially when it comes to size and mass - because there is a fuzzy boundary with large planets where if they become too large, they are considered a brown dwarf star. This is a body that almost made it to star status but doesn’t have enough mass or material for nuclear fusion to take place.

Astronomy Cast - Humans To Mars, Part 1 - Scientists
The 365 Days of Astronomy
From June 23, 2008. We’re learned about the failed missions to Mars in the past, and the current spacecraft, rovers and landers currently exploring the Red Planet. But the real prize will come when the first human sets foot on Mars. Robots are cheaper, but nothing beats having a real human being on the scene, to search for evidence of water and life.

UNAWE - A Missing Ingredient
The 365 Days of Astronomy
From September 10, 2020. The Universe is full of unanswered questions. And more than a few unquestioned answers! One of the biggest questions astronomers are trying to answer is what is the Universe made of? OK, sure, we know about protons, neutrons & electrons already. But astronomers also know that the Universe is full of dark matter, but we still don’t fully understand it…Dark matter is a mysterious and peculiar material that got its name because it doesn’t give off any light - it’s totally invisible at wavelengths our eyes can see. Dark matter remains as...

EVSN - Cosmic Billiards Leads to Inner Planetary Growth
The 365 Days of Astronomy
From September 28, 2021. The inner solar system was a wild and wooly place as the planets were forming, and new research shows that the collisions that formed Earth and Venus were likely of the hit-and-run variety. Plus, polar ice loss warps the planet, and a black hole eats a star. We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

The Actual Astronomy Podcast presents Astronomy Books. In this episode we discuss some of the best astronomy books with City Lights Bookstore owner Chris Wilcox. From poetry to the Milky Way we cover our favourite books on the astronomical table.
What are some of the titles that you’ve enjoyed and could recommend to our listeners?
* Arthur Koestler: The Sleepwalkers, in which Western civ gets stuck in geocentricity for 1500 years
* Thomas Kuhn: The Structure of Scientific Revolutions. Some dated conventions, but a fascinating sociological study of avant-garde science. This classic gave us the now-overused term “paradigm shift.”
* Michael Hoskin: The History of Astronomy: A Very Short Introduction
* Dava Sobel: The Planets
* Leslie C. Peltier Starlight Nights: The Adventures of a Star-Gazer
* Ronald Florence: The Perfect Machine: Building the Palomar Telescope
* Robert Zimmerman: The Universe in a Mirror: The Saga of the Hubble Space Telescope and the Visionaries Who Built It
* Emily Levesque: The Last Stargazers: The Enduring Story of Astronomy's Vanishing Explorers. A young professor’s assemblage of adventures -- her own, plus accounts gleaned from colleagues -- from the days when astronomers would travel to the big, remote observatories to capture their data.
What are some popular books on planetary science, astrophysics, and cosmology that are high up on your list of must reads?
* Mike Brown: How I Killed Pluto and Why It Had It Coming
* Adam Frank: The Little Book of Aliens
* Philip Plait: Under Alien Skies: A Sightseer's Guide to the Universe
* Becky Smethurst: A Brief History of Black Holes
* Carlo Rovelli: White Holes
* Moiya McTier: The Milky Way: An Autobiography of Our Galaxy
I think you even mentioned some poems?
* Benjamin Labatut: When We Cease to Understand the World and The MANIAC
* Kim Stanley Robinson: Galileo's Dream
* Tracy K. Smith Life on Mars: Poems
What makes a really good observing reference?
* Leslie C. Peltier, in his classic Guideposts to the Stars
* Walter “Scotty” Houston (his bio reminds us that he was an editor and English teacher by profession)
* Stephen James O’Meara, e.g., his Messier Objects 2nd ed.
* Sue French, in her inimitable continuation of Houston & O’Meara’s Deep Sky Wonders
* Howard Banich (his recent S&T article on M33 was his 33rd column for the magazine, so I hope he eventually pulls his writings and brilliant sketches into a bound collection)
What are some other useful books?
* Burnham's Celestial Handbook in three volumes
* Nightwatch (Dickinson, et al.)
* Harrington: Touring the Universe through Binoculars
* Hill: A Portfolio of Lunar Drawings
What do you keep handy at your desk?
* Pasachoff: Peterson Field Guide to the Stars and Planets
* Mitton: A Concise Dictionary of Astronomy
* Edgar: RASC Observer’s Handbook (current U.S. ed.)
* Beckett: RASC 2024 Observer’s Calendar
What are some good books to have in the field?
* Interstellarum Deep Sky Atlas, Field Edition* (Stoyan & Schurig)
* Sky Atlas 2000.0: Deluxe Edition (Tirion & Sinnott)
* Rukl: Atlas of the Moon
* Turn Left at Orion (Consolmagno & Davis)
* The Messier Observer’s Planisphere* from Celestial Teapot >46-cm diameter
What are a few indispensable texts from your collection:
* Swanson: NexStar User's Guide II
* Menard: New Perspectives on Newtonian Collimation
* Brown: All about Telescopes
* Telescopes, Eyepieces, and Astrographs: Design, Analysis, and Performance of Modern Astronomical Optics (Smith et al.)
* Astronomical Sketching (Handy et al.)
What books do you dip into when you need a jot between sessions under the stars.
* Freistetter: The Story of the Universe in 100 Stars
* Any of those splashy coffee table books loaded with astrophotography. While they may not represent visual astronomy's faint, mostly monochrome experience, they are stunning. And, as the imagers tell us, those long integrations and enhanced colors are scientifically useful.
* Cathay LeBlanc & David Chapman: Mi'Kmaw Moons: Through the Seasons. A picture book about Mi’Kmaq cosmology combines rich information and great storytelling with Loretta Gould’s gorgeous illustrations.
— Many astronomy-related books for kids are too delightful to let the youngsters have all the fun. Plucking a few stars from this constellation:
* Gaiter: The Mysteries of the Universe A lavish, outward sweeping reference
* McCulley: Caroline’s Comets A sweet, pictorial biography of C. Hershell
* Becker: You Are Light Spectra are for babies!
* 100 Poems: Outer Space, edited by Midge Goldberg From the Cambridge series
Are there any sentimental books in your library:
* Norton's Star Atlas (Epoch 1950) The stars have processed into a new epoch since these gate-fold pages were bound in boards of blue cloth. So it’s dated, and those boards are a bit warped, but I treasure this volume because it originally belonged to Col. Carl Hill, a kindly next-door elder when I was a kid. He was like a surrogate grandfather and the astronomy mentor who might’ve been had I shown interest at the time. He and his wife sold my folks the land where I grew up (and where I live). He had a backyard pier and enlisted my dad, an amateur machinist, to help him fabricate a wedge. There’s a sort of poignant regret I feel when holding this book.
