Travelers in the Night Eps. 887 & 888: Apophis Bound & Investigating the Mystery of How Life Formed

Travelers in the Night Eps. 899 & 900: Hitch Hiking an Asteroid to Mars & Earth Life From Mars

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus [https://twitter.com/Nmcanopus] ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org [http://travelersinthenight.org] From May 2026. Today's 2 topics: - Asteroids could provide a solution for the serious problem of how to protect astronauts from harmful solar and cosmic radiation during long duration space flights and thus eliminate the need for the spacecraft itself to have heavy shielding material. The idea is for the spacecraft to spend most of the journey inside the asteroid. - Some of the 635,000 impact craters found on Mars are the result of such violent impacts that pieces of Mars are ejected, travel around the solar system, and a few become one of the several hundred Martian meteorites which have been discovered here on Earth. An experiment is described which does not prove we are descendants of martian bacteria however it does improve our ability to protect our planet and understand where life may be possible elsewhere in the Universe.

AstroMan - D for Dark Sky Protection

When was the last time you saw the Milky Way? In this episode of Astroman, Exodus Chun-Long Sit explores how light pollution is changing our night skies, affecting wildlife, wasting energy, and limiting our view of the universe. Learn why protecting dark skies matters—and how simple actions can help bring the stars back. "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 Chun-Long 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".

Guide To Space - What Are Fast Radio Bursts? A Big Mystery in Astronomy

https://www.youtube.com/watch?v=ikdOTj6g_Zw [https://www.youtube.com/watch?v=ikdOTj6g_Zw] Hosted by Fraser Cain. From Apr 26, 2017. Here's a big mystery in astronomy: fast radio bursts. Brief shrieks of radio waves coming from space. What are they? Where do they come from? Astronomers have no idea. Team: Fraser Cain - @fcain / frasercain@gmail.com Karla Thompson - @karlaii Chad Weber - weber.chad@gmail.com You might think you're watching an educational channel, where I explain fascinating concepts in space and astronomy, but that's not really what's going on here. What's actually happening is that you're tagging along as I learn more and more about new and cool things happening in the Universe. I dig into them like a badger hiding a cow carcass, and we all get to enjoy the cache of knowledge I uncover. Okay, that analogy got a little weird. Anyway, my point is. Squirrel! Fast radio bursts are the new cosmic whatzits confusing and baffling astronomers, and now we get to take a front seat and watch them move through all stages of process of discovery.
