The 365 Days of Astronomy

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
From May 2025.
Today's 2 topics:
- My Catalina Sky Survey teammate Hannes Gröller was asteroid hunting in the constellation of Ursa Major with the University of Arizona 90 inch Bok telescope on Kitt Peak when he discovered a faint moving object surrounded by a tiny gas and dust cloud called a coma. May 19, 2028 comet C/2025 D1  (Groeller) reaches its closest point to the Sun some 14.1 times the Earth-Sun distance and thus sets the record for the comet which stays furtherest from the Sun.After rounding the Sun comet C/2025 D1 (Groeller) will head back into truly deep space perhaps never to return.
 
- On March 3, 2024 my Catalina Sky Survey teammate Kacper Wierzchos was asteroid hunting with our 60 inch telescope on Mt. Lemmon, Arizona when he spotted a fuzzy object in the constellation of Draco.  After Kacper reported his discovery to the Minor Planet Center, observers in Arizona, New Mexico, and Tenerife confirmed it to be a comet and it was given the name C/2024 E1 (Wierzchos).  Kacper's discovery has a hyperbolic orbit indicating that after coming slightly closer to the Sun than the planet  Venus on January 21, 2026 it will be ejected from the solar system never to return.

From January 7, 2026.
In this episode, we're pleased to say we get to focus on science, as we bring you hot Jupiters, a tear-drop shaped Jupiter massed… something…? - and news of objects getting torn apart and other objects getting merged together as our universe lights up our night.

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. [email protected]
In this podcast (Episode 519) we talk with a special guest & long-time listener Clint Reading (from Nebraska, formerly from Idaho) about his astro-tourism trips to OzSky which is a biannual event for amateur astronomers from the northern hemisphere to have the opportunity to see the southern skies. We learn how to prepare for an astronomy trip to Australia, what to bring to get the most out of a week under the southern stars and how you can take advantage of these events. This is part of our New Years resolution to have more listener guests since there are so many of you doing astronomy activities that Shane and I can only dream of. 
 
Introduction:
So welcome to the show Clint!
We've been chatting for years so it's great to speak in person.
Can you tell us a little about where you are and how you became interested in astronomy?
How have you progressed through the hobby?
Are you in any clubs?
Are you visual, imaging, both?
What equipment are you using?
You've had some interesting adventures I recall you went to Lowell a couple years back to a public event, how was that?
 
Main Show:
Let's talk about your trip down south to OzSky (not to be confused with Ozzfest)
So where is OzSky and what is it exactly?
What is OzSky exactly?
How is it organized? days/nights?  Speakers?
Cost?
Other amateurs?
How did you plan for the trip?
What did you take for equipment and observing guides?
What equipment do they provide?
Day trips?
 
Conclusion:
Does anyone have anything to add?
Thanks for joining us today Clint, we really appreciate it.
Clear skies!

Hosted by Steve Nerlich.
Well… Cheap Astronomy confirms some mysteries are still mysteries!
Dear Cheap Astronomy – Is warp drive looking any more possible?
Well, no, insofar as it looks about as possible as it ever did, which is to say, it's probably
impossible, but at the same time, it's best to never say never. As we've covered before, the
nature of space-time precludes the possibility of faster than light travel simply because light
travels as fast as it is possible to travel in space-time.
 
Dear Cheap Astronomy – What is X-17?
X-17 is a mysterious and somewhat hypothetical particle. Somewhat hypothetical
means there is a bit of evidence for its existence, although it's more a case of there being
evidence of something unusual, rather than definitive evidence of a new particle that does something
unusual.
