The 365 Days of Astronomy

All Hail Dust! Hosted by Dr. Paul M. Sutter. Why is dust so annoying? But where does it come from, and what can it do? And is dust responsible for the creation of life? I discuss these questions and more in today's Ask a Spaceman !   Support the show: http://www.patreon.com/pmsutter All episodes: http://www.

Using the Gemini North telescope in Hawai'i and the European Southern Observatory's Very Large Telescope, a team of astronomers measured wind speeds on seven very hot, Jupiter-like exoplanets. The observations revealed that the winds on these planets are most likely governed by magnetic fields, providing the first robust measurement of magnetic activity on planets outside the Solar System. In this...

From June 3, 2026. In this episode, we're going to look at Psyche's success at Mars, the cool 3I-ATLAS science coming from Europa Clipper and JUICE en route to the Jupiter system, and we also look at JWST's efforts to study exoplanetary atmospheres and the weird weather of other worlds.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  ...

https://www.youtube.com/watch?v=larzCw9Vn-w From Jul 21, 2020. When the Apollo astronauts first landed on the Moon, they couldn't go far on foot. That's why the three final missions were equipped with Lunar Roving Vehicles, or Moon buggies, which allowed the astronauts to cover much more ground and do more science.   Now that NASA is returning to the Moon by 2024 as part of its Artemis Program, it...

Paul Hill and Dr. Jenifer "Dr. Dust" Millard host.   Damien Phillips, John Wildridge and Dustin Ruoff produce. This month a bit of a JWST fest with news about the cosmic Web (Webb?! ) and those little red dots that seem to be breaking cosmology. There is also our normal skyguide and moon guide.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production c...

Hosted by Dr. Paul M. Sutter. What does is mean for the Universe to have a wave function? How does Hawking's "no boundary" proposal mean that the Universe comes from itself? And is it really the final answer? I discuss these questions and more in today's Ask a Spaceman!   Support the show: http://www.patreon.com/pmsutter All episodes: http://www.
