Guide To Space - What Are Fast Radio Bursts? A Big Mystery in Astronomy
The 365 Days of Astronomy
Hosted by Fraser Cain. From Apr 26, 2017. Here's a big mystery in astronomy: fast radio bursts. Brief shrieks of radio waves coming from space. What are they? Where do they come from? Astronomers have no idea. Team: Fraser Cain - @fcain / frasercain@gmail.com Karla Thompson - @karlaii Chad Weber - weber.chad@gmail.com You might think you’re watching an educational channel, where I explain fascinating concepts in space and astronomy, but that’s not really what’s going on here. What’s actually happening is that you’re tagging along as I learn more and...

Astronomy Cast Ep. 41: The Rise of The Supertelescopes
The 365 Days of Astronomy
Hosted by: Fraser Cain () and Dr. Pamela L. Gay () From June 18, 2007. The last decade has been the golden age of astronomy, with new observatories and space telescopes pushing out our understanding of the Universe. We see billions of light years away, watch dynamic events unfold in almost real-time, and see into every corner of the electromagnetic spectrum. But just you wait: things will only get better. Here come the supertelescopes! We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs. Just visit: and donate as much as you...

Travelers in the Night Eps. 897 & 898: Kacper’s Comet & Pandora
The 365 Days of Astronomy
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. From May 2026. Today's 2 topics: - In 2007 a small icy object moving in the constellation of Ursa Minor crossed the orbit of Pluto at a speed of approximately 4.2 mi/s starting its journey towards the inner solar system. It was between the orbits of Saturn and Jupiter traveling at some 9 mi/s towards the Sun, when my Catalina Sky Survey teammate Dr. Kacper Wierzchoś discovered it on March 3, 2024, while asteroid hunting, in...

NOIRLab - The First Magnetar Progenitor
The 365 Days of Astronomy
Neutron stars, the compact remains of a massive star following a supernova explosion, are the densest matter in the Universe. Some neutron stars, known as magnetars, also claim the record for the strongest magnetic fields of any object. How magnetars, which are a mere 15 kilometers across, form and produce such colossal magnetic fields remains a mystery. New observations by a team of astronomers, including NSF’s NOIRLab’s Dr. André-Nicolas Chené, may shed important light on the origin of these magnetic powerhouses. Using various telescopes around the globe, including the...

EVSN - After Hours: Exploring Physics Through Spaceflight Missions with author Trisha Muro
The 365 Days of Astronomy
Hosted by Dr. Pamela L. Gay. From July 8, 2026. The physics behind modern spaceflight explores everything from aerodynamics to thermodynamics with a lot of kinematics playing a role along the way. We welcome on guest Trisha Muro to discuss her new book, "It's (Just) Rocket Science", which explores how we can learn physics through spaceflight missions.

UNAWE Space Scoop - Why Does Jupiter Have Bigger Moons Than Saturn
The 365 Days of Astronomy
Hosted by our editor, Richard Drumm. Jupiter and Saturn are the gas giants in our Solar System. Ummm… Uranus & Neptune are now called ice giants. But back to Jupiter & Saturn. They are the largest planets, have the most moons compared to the other planets, and if that isn’t cool enough, they’re home to some of the largest moons in the Solar System. Saturn has 280 or more moons in total, a total that seems to be changing daily. Jupiter has over 100 known moons so far. As for me, I don’t even try to keep count any more. Here’s where things get really interesting:...

Awesome Astronomy - When Cosmologists Get Spicey
The 365 Days of Astronomy
Paul Hill & Dr. Jenifer “Dr. Dust” Millard host. Damien Phillips, John Wildridge and Dustin Ruoff produce. This month it appears cosmology is saved, Swift maybe saved and exoplanets have their magnetosphere measured. Jeni has been in the States where she may have been turned into an android visiting Silicon Valley.

Ask A Spaceman Ep. 275: Why Can’t the Universe Be Cyclic?
The 365 Days of Astronomy
Hosted by Dr. Paul M. Sutter. What are the weaknesses of inflation theory? How did the ekpyrotic theory attempt to improve it? How did it open up its own can of worms? I discuss these questions and more in today’s Ask a Spaceman! Support the show: All episodes: Watch on YouTube: Read a book: Keep those questions about space, science, astronomy, astrophysics, physics, and cosmology coming to #AskASpaceman for COMPLETE KNOWLEDGE OF TIME AND SPACE! Big thanks to my top Patreon supporters this month: Justin G, Chris L, Alberto M, Duncan M, Corey D, Michael P, Naila, Sam...

Astronomy Cast Ep. 6: Ep. 6: More Evidence For the Big Bang
The 365 Days of Astronomy
Mon 06: Astronomy Cast Ep. 6: Ep. 6: More Evidence For the Big Bang From October 16, 2006. Last week’s episode started out with a bang… a Big Bang. This week we continue our discussion into the beginning of everything. We present three additional lines of evidence that have led astronomers to the conclusion that our Universe started out as a singularity 13.7 billion years ago, and has been expanding ever since. Fraser Cain: So Pamela, last week we started out with the big bang and discussed the cosmic microwave background radiation. Now, if people still aren’t convinced that the...
info_outlineDr. 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 March 2026.
Today's 2 topics:
- In 1892 the world’s largest telescope, the Lick Observatory’s 36 inch refracting telescope made the news when E.E. Barnard discovered, Amalthea, the 5th moon of Jupiter. In 2025 this historic telescope made the news again when on Christmas morning winds of 114 mph blew off a 3 ton piece of the shutter on its dome. The adaptive optics research pioneered at Lick Observatory helped in the creation of the twin giant 10 meter telescopes that sit atop Mauna Kea in Hawaii.
- Astronomers using the 8.1 m Gemini South Telescope in Chile were excited by the fact that 467P (LINEAR-Grauer)’s Centaur like orbit had been changed as the nucleus emitted rocket like bursts of gases as it was warmed by the Sun. Inert inactive asteroids orbit the Sun following the law of gravity whereas active asteroids can emit little rocket like bursts of gas which can change their path about the Sun in interesting ways. It is important to study objects like 467P (LINEAR-Grauer) to make sure their path about the Sun doesn’t change to make them a threat to our home planet.
