Why is it so hard to get a picture of the Milky Way? How much of our galaxy have we mapped? What the heck is a “barred spiral” and what does that have to do with our core? I discuss these questions and more in today’s Ask a Spaceman!   This episode is sponsored by BetterHelp.

The 365 Days of Astronomy

Streamed live Feb 12, 2024. Last week we talked about sample return missions from the Moon and Mars, but scientists have retrieved samples from other objects in the Solar System, including comets and asteroids. What does it take to return a piece of rock from space, and what have we learned so far?   This video was made possible by the following Patreon members: Jordan Young BogieNet Stephen Veit ( rhymes with right) Jeanette Wink Siggi Kemmler Andrew Poelstra Brian Cagle David Truog Ed David Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela   We've added a new way to donate to...

The 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: - Covered by a blanket of lunar soil to protect it from BB sized meteoroids arriving a gunshot speeds, a village is nestled in a large crater on our moon. The individual structures are connected together by tunnels. The site was chosen to access the water and metals which were brought to the site by asteroid impacts. - Blinded by inappropriate outdoor night lighting, much of humanity is now unaware of the...

Paul Hill and Dr. Jenifer “Dr. Dust” Millard host.  Damien Phillips, John Wildridge and Dustin Ruoff produce. This month we explore:  - The exciting announcements from the European Space Agency as they outline their new missions for the 2030s.  - LISA, a space based gravitational wave detector and… - EnVision, a Venus mission that will map the surface and under-surface of that planet in unprecedented detail.    We have the usual skyguide, a chat about recent lunar missions and emails from the listeners.    Bio -  Awesome Astronomy explores the...

The 365 Days of Astronomy

From October 25, 2023. Around our parent collaboration, CosmoQuest, Halloween is, hands-down, the most beloved season of the year. Costumes are worn. Yards are decorated. We are here for all the strangers that knock on our door - the weirdos, the witches, and the oh-so-very-many werewolves - and there will be as much candy as we can afford given out. We know we are not the only ones.    With about a week to go, we know that any day now, NASA, ESA, ESO, and others will begin releasing their spooky season images. There will be nebulae cropped with the contrast adjusted just so to...

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. The Actual Astronomy Podcast presents Astronomy Books. In this episode we discuss some of the best astronomy books with City Lights Bookstore owner Chris Wilcox. From poetry to the Milky Way we cover our favourite books on the astronomical table.   What are some of the titles that you’ve enjoyed and could recommend to our listeners? * Arthur Koestler: The Sleepwalkers, in which Western civ gets stuck in geocentricity for 1500 years * Thomas Kuhn: The Structure of Scientific Revolutions. Some dated...

SETI Live - “The Big One”: The Most Powerful Marsquake Ever Detected show art SETI Live - “The Big One”: The Most Powerful Marsquake Ever Detected

The 365 Days of Astronomy

Recorded 16 November 2023. On Earth, we understand how and where earthquakes happen due to the discovery of plate tectonics – the continental crust’s creation, movement, and destruction. However, when astronauts placed seismometers on the lunar surface during NASA’s Apollo mission era, those instruments recorded quakes on the Moon.    In the 1970s, the Viking landers also recorded quakes on the surface of Mars. Since neither of these worlds has plate tectonics, scientists set about collecting more data to understand the phenomena, which led to the recent NASA InSight...

The 365 Days of Astronomy

From July 29, 2023. Aside from our own solar system, one of the most studied stellar systems lies about 40 light-years away in the direction of the constellation Aquarius. Using ground and space based telescopes like Spitzer, Kepler, Hubble, and, now, the James Webb Space Telescope, astronomers are looking hard at the seven rocky exoplanets orbiting the TRAPPIST-1 star.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: and donate as much as you can!

The 365 Days of Astronomy

Streamed live on Feb 5, 2024. We’ve sent robots to other worlds, but the amount of science we can deploy to another planet can’t compare with the vast science labs we have on Earth. That’s why more and more missions are for a sample return, bringing pieces of alien worlds back to Earth, where we study them with proper equipment.   This video was made possible by the following Patreon members: Jordan Young BogieNet Stephen Veit ( rhymes with right) Jeanette Wink Siggi Kemmler Andrew Poelstra Brian Cagle David Truog Ed David Gerhard Schwarzer THANK YOU! - Fraser and Dr. Pamela  ...

Today's 2 topics: - The moon is being hit by objects in the present epoch. Fresh lunar craters tell us about objects which enter the Earth-Moon system. - Jupiter protects us as well as directs some objects our way. Jupiter, the king of our solar system, has provided us with a place to stand and air to breathe.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production...

Asteroid Metis 9 at 8.4 magnitude opposition. Discovered by Andrew Graham on 25 April 1848, at Markree Observatory in Ireland. Metis (minor planet designation: 9 Metis) is one of the larger main-belt asteroids. It is composed of silicates and metallic nickel-iron, and may be the core remnant of a large asteroid that was destroyed by an ancient collision. Metis is estimated to contain just under half a percent of the total mass of the asteroid belt.

- Dec 26 Full Moon

- Dec 28 Asteroid 5 Astraea at Opposition! 5 Astraea is an asteroid in the asteroid belt. Its surface is highly reflective and its composition is probably a mixture of nickel-iron with silicates of magnesium and iron. It is an S-type asteroid in the Tholen classification system. Astraea was the fifth asteroid discovered, on 8 December 1845, by Karl Ludwig Hencke and named for Astraea, a Greek goddess of justice named after the stars. It was his first of two asteroid discoveries. The second was 6 Hebe. A German amateur astronomer and post office headmaster, Hencke was looking for 4 Vesta when he stumbled on Astraea. The King of Prussia awarded him an annual pension of 1,200 marks for the discovery.

- Dec 30 Double Shadow Transit on Jupiter YES!
