Astronomy Cast Ep. 784: Pulsar-Powered Science
The 365 Days of Astronomy
Off label uses for Pulsars… Hosted by: Fraser Cain () and Dr. Pamela L. Gay () Streamed live on Feb 16, 2026. Pulsars are dead stars and fascinating in their own right, but astronomers can use their predictable rotation for exploring the cosmos in a series of amazing ways. We can detect gravitational waves, navigate the solar system, test general relativity and find exoplanets. Pulsars are the time keepers of the sky, with their precise ticking allowing researchers to track gravitational waves, find exotic planets, and study weird relativistic effects. Come learn about how pulsars can be...

Astronomy Cast Ep. 783: Cataclysmic Variable Stars
The 365 Days of Astronomy
Hosted by: Fraser Cain () and Dr. Pamela L. Gay () Streamed live on Feb 16, 2026. There are many types of variable stars. Today we’re gonna talk about cataclysmic variable stars, which are the result of a white dwarf stealing material from a companion star. And this whole process makes supervillain Pamela happy. Gravity is the weakest force, but on the scales of stars, it is capable of great violence. In this episode, we look at the wild physics of cataclysmic variables: binary star systems where one star is a predatory compact stellar remnant, while the other is a victimized normal star....

ASTROMAN - Solar Eclipse
The 365 Days of Astronomy
Episode 14. Our Sun is more than a glowing ball in the sky. It’s a dynamic, ever-changing star at the peak of its solar cycle. In this episode of ASTROMAN: The Dark Sky Guardian, we learn how to safely observe sunspots and solar flares, and why studying solar activity helps protect satellites, power grids, and even predicts auroras. “ASTROMAN: the Dark Sky Guardian” is a podcast channel that aims to explore popular science in multiple disciplines and research on interdisciplinary approaches, such as sustainability, dark-sky protection, astrophotography, space exploration,...
info_outlineHi everybody, I’m Rob Webb, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare. We’ll start by talking about January’s big events, then highlight the naked eye planets, and finish up with the lunar phases, so you can plan ahead better than me.
January 2025 is a PLANETARY month! Mars gets big, Mars gets occulted, Mars gets outshined by Venus, Saturn, and Jupiter, then Venus and Saturn pass right by each other, and a brief but intense meteor shower shows up.
13th - Occultation of Mars - MORE than a close encounter, Mars will be right next to the Moon all night, except for about an hour when the Moon occults Mars. Around Philadelphia, the occultation starts at 9:17pm, when the Moon passes right in front of Mars. This lasts until about 10:32pm, when Mars pops back out on the other side of the Moon.
