The 365 Days of Astronomy

Paul Hill and Dr. Jenifer "Dr. Dust" Millard host. 
Damien Phillips, John Wildridge and Dustin Ruoff produce.
Angry episode where Paul and Jeni have their blood boiled by the decision to defund Jodrell Bank Observatory and the plans to launch over a million satellites, thousands of which will be brighter then the full moon!

From April 21, 2008.
Our senses can only detect a fraction of the phenomena happening in the Universe. That's why scientists and engineers develop detectors, to let us see radiation and particles that we could never detect with our eyes and ears. This week we'll go through them all, so you can understand how we see what we can't see.

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 November 2025.
Today's 2 topics:
- Throughout history small close approaching space rocks have been a part of our environment. Now, thanks to improved telescopes and cameras, asteroid hunters are routinely discovering these small asteroids as they pass closer than the Moon is to us. Since these tiny asteroids are only bright enough to detect for a few days out of their long, many month duration paths about the Sun, astronomers have had difficulty in determining how many of these small space rocks may exist in near Earth space. This effort received more emphasis when a house sized space rock exploded over Chelyabinsk, Russia in 2013 releasing about 10 times the energy of the Hiroshima atomic bomb.
 
- Jupiter has been observed throughout human history and is so bright that you can even spot it under the artificial light dome of one of our cities. Even so it is less than 40 years ago that we were first able to view Jupiter in detail as the Voyagers streaked by it. Jupiter contains more than twice the mass of all of the other planets, dwarf planets, asteroids, and comets in our solar system combined. Eons ago, our solar systems very own giant planet, Jupiter, appears to have cleared out the inner solar system leaving enough rocky debris to form Mercury, Venus, Earth, and Mars.

Hosted by Avivah Yamani, our Director!
Was Betelgeuse ever truly alone? For over 100 years, astronomers searched for a hidden companion to Orion's famous red supergiant. Now, new observations from ESO's Very Large Telescope have revealed the clearest evidence yet that Betelgeuse has a stellar companion. Discover the science, the mystery, and why this finding is changing our understanding of one of the sky's most famous stars.

From February 10, 2021.
Hosted by Dr. Pamela L. Gay.
Scientists collected fresh data on Orion's bright star Betelgeuse to try and understand this star that caused so much controversy. They found it's smaller than previously calculated, and last year's dimming was likely caused by dust, but it's also more complex than thought. Plus, galaxies, Earth's forests, ice on Mars, and Saturn's moon Rhea.
