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.

Dr. 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 July 2025.
Today's 2 topics:
- Recently my Catalina Sky Survey teammate Dr. Hannes Gröller and I traveled to the Gila Cliff Dwellings National Monument to install two night sky meters which will enable this wonderful national treasure to become an international dark sky park. Surrounded by vast tracts of unoccupied public land and having an abundance of clear weather the Gila Cliff Dwellings National Monument and the Cosmic Campground International Dark Sky Sanctuary both in New Mexico are among the best places in the world to view the natural night sky.
- Sadly humans seem to be in the process of creating a cosmic land fill which will blot out much of the cosmos.

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, astronomy innovation, inclusive science communication, and STEAM Education by integrating science and arts.
 
Exodus CL Sit, also known as the ASTROMAN, is a transmedia astronomy educator, popular science author, STEAM educator, and science communicator in Hong Kong. He is recently the National Astronomy Education Coordinator (Chair of Hong Kong, China) of the International Astronomical Union and President of Starrix. He was also an International Committee Member of the Dark Sky International, regularly organizing public lectures at the Hong Kong Space Museum and the Hong Kong Science Museum. He was also the author of a popular science book "Decoding the Starry Night: A Guide to Stargazing and Astrophotography".
