EVSN - Following the Water Toward Climate Change
From April 10, 2024.
This week’s episode is brought to you by last week’s terrible weather. While experiencing hail and thunder IRL, we also saw press release after press release and article after article discussing climate change. This one-two punch of new science and the need for a new roof means we will touch on climate change in our closer look this week. We apologize in advance; it’s not pretty out there -- unless you like storm chasing, then it’s kind of the stuff of dreams at the moment.

Actual Astronomy - Globular Star Clusters with Peter Jedicke
Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com
Our guest today is Peter Jedicke who was National President of the Royal Astronomical Society of Canada from 2004 to 2006 and is now a Fellow of the RASC. He is also Honorary President of the RASC London Centre. His favourite astronomical topic, both astrophysically and as an observer, is globular clusters and co-authored the RASCC Observer’s Handbook section on Star Clusters. Peter co-authors the Star Clusters section of the RASC Observer's Handbook. Lastly, Peter helped start the list of asteroid names with Canadian connections which will be our topic today but….
Let’s chat about globular star clusters since, as you pointed out Peter, it's best to focus on a narrow topic as the show time whips by!
* Helen B. Sawyer [Hogg], 1947. Out of Old Books-Catalogues of Nebulous Objects in the Eighteenth Century. Journal of the Royal Astronomical Society of Canada, Vol. 41, p. 265-273
Also: Helen B. Sawyer [Hogg], 1948. Astronomical Journal, Vol. 53, p. 117
* * What are Star Clusters?
* - 2 types: OC and GC what is the diff…maybe we’ll do Open Clusters another time.
* - Age & Number of stars which equate to variations in CLs + magnitude, colour + number.
* Where do they come from
* So what is a globular star cluster exactly?
* Why old-rich-symetrical-live in galactic halo?
* What are the differences in concentration and spectral classifications?
* What is it you enjoy about globulars?
* Variable stars in globular clusters
* Helen Sawyer Hogg & my one summer working as a "research assistant" at Western U.
* Something about where globular clusters fit in with cosmology. Age & role in galaxy mergers.
* How many have you observed?
* Where have you traveled to observe them?
* Which are your favourites?

SETI Live - On the Trail of Fireballs: Tracking Meteors and Finding Meteorites
Only eight times in history have scientists found an asteroid, tracked its trajectory toward Earth, and caught the resulting fireball on cameras. The latest of these eight events happened in January 2024, with the discovery of asteroid 2024 BX1, a mere three hours before impacting the atmosphere over Europe. And of course, the SETI Institute's own Dr. Peter Jenniskens was hot on the trail, flying to Germany to help search for meteorite fragments. Within the week, several pieces were discovered, and early analysis found that they belong to a rare group of meteorites called "aubrites".
Join communications specialist Beth Johnson as she chats with Dr. Jenniskens about this search, the resulting find and its implications, and prior work hunting for meteorites around the world.

Astronomy Cast Ep. 9: Einstein's Theory of Special Relativity
https://www.astronomycast.com/2006/11/einsteins-theory-of-special-relativity/
From November 6, 2006.
It’s all relative. How many times have you heard that? Well, when you’re traveling close to the speed of light, everything really is relative; especially the passage of time. This week, Fraser and Pamela give you the skinny on Einstein’s Special Theory of Relativity. After listening to a few thought experiments, you too should be able to wrap your head around this amazing theory.

Travelers in the Night Eps. 723 & 724: Very Close One & Aten
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
Today's 2 topics:
- Ten hours and 46 minutes after my Catalina Sky Survey teammate Greg Leonard discovered a Toyota RAV4 sized space rock, now named 2018 UA, streaking through the constellation of Pegasus at 8.8 miles/second, this tiny asteroid passed less than 1/2 the distance of the communications satellites to the surface of planet Earth.
- Aten Asteroids are stealthy space rocks which can be dim and hard to detect since for most of their path about the Sun their illuminated side is facing away from us.
