The 365 Days of Astronomy
From Jan 23, 2018. The internet. It gives us an instant connection to the sum of human knowledge, but it also lets misinformation travel at the speed of light. Everyday I get comments about how people will believe we’ve been to space after I show them evidence of actual spacecraft taken in space and not CGI mock-ups. Challenge accepted. Here come a whole bunch of photos of spacecraft taken in space. Actually, I don’t really care if you believe it or not. I was just so excited about some of the fantastic pictures of spacecraft - taken by spacecraft - that I decided to dedicate...
info_outline Ask A Spaceman Ep. 232: Is Space Tourism A Good Idea?The 365 Days of Astronomy
Why are private space companies pushing tourism? Is there a future for tourism in space? Is this an overall good thing for space exploration? Paul Sutter’s personal hot take: “Meh. I find space tourism kinda interesting... Space tourism isn’t moving the needle much in any direction.” This episode is sponsored by Factor meals. 35 different restaurant-quality meals with premium ingredients and 60 different add-ons!

info_outline Astronomy Cast Ep. 726: Looking Back Over The SummerThe 365 Days of Astronomy
Streamed live Sep 9, 2024. We made all sorts of predictions, and some of the stuff we didn't know about last July, somehow, we still don't know about as we set up this episode on September 3! Join us for the first episode of Season 18 as we review all the crazy space science that happened during our Summer Hiatus.

info_outline Travelers in the Night Eps. 287E & 288E: Sensing A Comet & Close OneThe 365 Days of Astronomy
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. Today's 2 topics: - More than 400 years ago Galileo Galilei expanded human vision using a telescope to view the cosmos. Since then humans have extended their senses to view the Universe in x-rays, ultraviolet, infrared, radio, and other portions of the electromagnetic spectrum not accessible to our senses. In a pioneering effort, Ekaterina Smirnova has employed the spectroscopy, magnetometry, and molecular data collected by...
info_outline NOIR Lab - The First Kilonova ProgenitorThe 365 Days of Astronomy
Kilonova form when two neutron stars collide. They were first discovered by their gravitational wave emissions. In this podcast, NOIRLab’s Dr. André-Nicolas Chene described the discovery of a system that will become a kilonova in the future. Bios: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.. André-Nicolas Chene is an associate astronomer at NOIRLab. He completed his PhD at the Université de Montréal in 2007 and learned everything about the fundamentals of astronomical observations at the Observatoire du Mont...

From Wednesday, September 4, 2024. Let's take a fast-paced journey thru all that's new in space and astronomy, including new info on the origins of the Dino Killing asteroid, a star being nommed by a star, a deep dive into Mars exploration, and tales from the launch pad.

info_outline Cheap Astronomy - Dear CA #109: PlanetsThe 365 Days of Astronomy
Things that orbit the Sun and clear their orbits. Dear Cheap Astronomy – What happens when worlds collide? The outcome of a collision between two planets depends on the speed of the collision, the angle of the collision and the relative masses of the two bodies and their composition – think rocky planets versus gas giants for example. A small planet approaching a large planet slowly might get tidally stretched and break up into pieces, but a fast moving one might impact before there’s been time for gravitational stretching to break it up. Dear Cheap Astronomy – Why is Mars’...
info_outline Awesome Astronomy - British Planetary Science ConferenceThe 365 Days of Astronomy
#147 part 1 - September 2024. Paul Hill and Dustin Ruoff host. Damien Phillips, John Wildridge and Dustin Ruoff produce. A bit different this month as Paul (in a tent) is joined by Dustin (in a boudoir) as they chat about: - Aurora on Ganymede, - Starliner, - Polaris Dawn, - Blue Origin and… - Dustin shares an interview with John S. Gianforte at a local astronomy festival. Awesome Astronomy explores the frontiers of science, space and our evolving understanding of the Universe. Join Paul & Jeni for informative and fun astronomy programmes dedicated...
info_outline Exoplanet Radio Ep. 25: Trillions of Worlds Without StarsThe 365 Days of Astronomy
From August 23, 2023. Astronomers estimate that there are more free roaming planets in our galaxy than there are planets in orbit around stars. In fact, rogue exoplanets - planets with no star whatsoever - far outnumber all other planets in our galaxy, by 20 times. Trillions of worlds wandering alone.

info_outline Astronomy Cast Ep. 32: The Search For NeutrinosThe 365 Days of Astronomy
Trillions of neutrinos are produced in our Sun through its nuclear reactions. These particles stream out at nearly the speed of light, and pass right through any matter they encounter. In fact, there are billions of them passing through your body right now. Learn how this elusive particle was first theorized and finally discovered. I don’t want to alarm the listeners but there is a flurry of particles from the Sun passing through each and every one of you right now. A lot of particles. In fact, there are 50 billion solar neutrinos passing through every one of us every second. Don’t worry,...

Today's 2 topics:
- More than 400 years ago Galileo Galilei expanded human vision using a telescope to view the cosmos. Since then humans have extended their senses to view the Universe in x-rays, ultraviolet, infrared, radio, and other portions of the electromagnetic spectrum not accessible to our senses. In a pioneering effort, Ekaterina Smirnova has employed the spectroscopy, magnetometry, and molecular data collected by the Rosetta spacecraft to create watercolor paintings, sculptures, a musical collaboration, and an augmented reality project to create new art forms.
- My Catalina Sky Survey teammate Rose Matheny had no way of knowing that the fast moving point of light that she had just discovered would create such a stir. Rose sent in her discovery and followup observations to the Minor Planet Center where astronomers calculated that her discovery would make a very close approach to Earth about two days later and gave it the name 2016 RB1. More than two dozen observatories around the world tracked 2016 RB1 as it came towards us.
