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 Canada-France-Hawai'i Telescope (CFHT) on Maunakea, the researchers have identified a new type of astronomical object — a massive magnetic helium star (an unusual variant of a Wolf-Rayet star), which may be the precursor of a magnetar. 
In this podcast, André-Nicolas Chené describes the process of finding the first known potential magnetar progenitor.
 
Bios: 
- Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab in Tucson, Arizona.
- Dr. André-Nicolas Chene is an associate astronomer at NOIRLab. He completed his PhD at the Université de Montréal in 2007 and learned everything about the fundamentals of astronomical observations at the Observatoire du Mont Mégantic. He was research fellow at the NRC Herzberg Astronomy and Astrophysics Research Centre and postdoc jointly at the Universidad de Concepción and the Universidad de Valparaíso before joining the Gemini Observatory (now a program of NOIRLab) in 2013. For almost 10 years, André-Nicolas took part in every phase of a Gemini observing program life cycle and has played a central role in Gemini's user support effort. André-Nicolas's research interests are massive stars, hot winds, star clusters, and stellar evolution.

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.

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: Jupiter has four big moons, including Ganymede, the biggest one in the whole Solar System. Jupiter's Galilean moons from closest to farthest are Io, Europa, Ganymede & Callisto. 
 
The first 3 are in a 1:2:4 orbital resonance with Io making 4 orbits, Europa 2 and Ganymede 1. It's been calculated that Ganymede & Callisto were in a 7:3 resonance a couple million years ago but are slipping toward a 6:3 which is a nice, stable 2:1 resonance. Callisto will likely fall into that resonance in a billion and a half years making the system 1:2:4:8. Nice & stable.

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.

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!
