The 365 Days of Astronomy

Streamed live on Feb 19, 2024. [My apologies for Fraser’s audio dropouts. We’re not sure how it happened as it wasn’t happening at his studio. Audio is a black art, IMHO. Rich) Last week we learned that Russia might be planning nuclear weapons to take out satellites in space. What is the current and future possibility of weapons in space and what are the treaties designed to prevent them?   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...

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: - We will probably never know the details of the collision that put my Catalina Sky Survey teammate Carson Fuls' recent discovery, 2016 HD3, on its current path. What we do know is that Carson's new space rock is about 25 feet in diameter and in the next 100 years will make 53 close approaches to planet Earth and 12 to our sister planet Venus. In 2016 this small object passed to near both the Earth and our...

The 365 Days of Astronomy

From Wednesday, January 24, 2024. If you take a compass and follow its pointy little needle, you will end up in Northern Canada but not at the North Pole. If you have a boat, you'll end up on Ellesmere Island wondering where Santa is hiding.    The fact that the rotational north pole of the Earth and the magnetic pole of the Earth don’t align means that if you want to actually get to the Earth’s rotational North Pole - the one the pole sticks out of on your globe - you have to look up corrections online and veer a little bit in whatever direction the correction happens to be at...

Expanding and lifting. The Hubble – Lemaitre Law: v=H0D V (Velocity) equals D (distance) times H-nought (the Hubble-Lemaitre constant).   This formula describes the relationship between the distance of galaxies and the velocity at which they are receding from us. Put simply it says the farther away a galaxy is, the faster it is receding.   This relationship has been widely accepted as evidence that the Universe must be expanding, with the notable exception of Edwin Hubble who was happy there was a relationship between the redshift of galaxies and their distance, but never really...

The 365 Days of Astronomy

Recorded 30 November 2023. In a new study published in the Astronomical Journal, researchers used the known population of exoplanets to set better thresholds for planetary effects on signals from ETIs (extraterrestrial intelligences). Megan Grace Li, a Ph.D. student at UCLA in UCLA SETI, conducted this research as a National Science Foundation Research Experience for Undergraduates intern in the Breakthrough Listen project at the Berkeley SETI Research Center. Join Megan as she chats with Beth Johnson about her work and what it means for the future of SETI searches.   We've added a new...

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...

More Episodes

Each week, when we set off to do this show, we start with one core idea: We want to tell you what is new in space and astronomy… and remember Earth is a planet too. When we select stories, we try to find the ones we’re excited to talk about over coffee, or the ones we know we will be sharing randomly with strangers who make the mistake of asking, “What do astronomers do?” We are here, week after week, to inflict space on others, and we hope that when we do you will return the favor and inflict this show on others. (This episode was originally released on YouTube June 24, 2023.)
