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.

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...

Travelers in the Night Eps. 895 & 896: Tracking Space Junk & Sneaky But Potentially Dangerous
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 April 2026. Today's 2 topics: - According to NASA an average of one catalogued piece of space junk per day has come down to Earth over the past 50 years. Research is described which can track space junk in the atmosphere and provide the starting location and altitude for tracking clouds of environmentally problematic toxic chemical and/or nuclear contaminants released by the disintegration of reentering spacecraft....

info_outlineFrom May 21, 2025.
This week, we take a closer look at the weirdly twisty search for a possible planet in our outer solar system. We'll also take in the happy science of aurorae here, at Jupiter, and over Neptune, as well as a bunch of weird discoveries that has some people screaming "It's Aliens!" (it's not aliens).
