Hosted by Dr. Paul M. Sutter. How can anyone agree on the age of the Universe? And how can we be so confident if it's all just a bunch of models?

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 ai...

In this episode, we take a closer look at how the increasing number of rockets and satellites going up mean there is also an unfortunate increase in the space junk coming down. We also cover dramatic weather, stars dying and disappearing, and update you on Maven and Paranal Observatory.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  ...

Astronomers just found something cool!   Typically, most Sun-like stars host planets between the size of Earth and Neptune called 'super-Earths' or 'sub-Neptunes'. These planets often orbit their stars even closer than Mercury orbits our Sun. They're mostly rocky super-Earths or they have a thick atmosphere and a rocky core and are sub-Neptunes. They're the most common types of planet found in our...

Hosted by Dr. Paul M. Sutter. Why is math so effective at describing the Universe? What is reality is made of math? What does it mean for us to be conscious beings in a mathematical structure?

Sweeping winds of vaporized metals have been found in a massive cloud that dimmed the light of a star for nearly nine months. This discovery, made with the Gemini South telescope in Chile offers a rare glimpse into the chaotic and dynamic processes still shaping planetary systems long after their formation. In this podcast, Dr. Nadia Zakamska describes the discovery of this object, stemming from a...

From May 21, 2020. Join us today as we discuss the impressive work by an undergraduate student who figured out how galaxy mergers influence the growth of supermassive black holes. We talk about a gigantic galaxy found in the early universe.
