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:
- Hungarian astronomer and geography teacher Krisztián Sárneczky was asteroid hunting in the constellation of Lynx with 0.6m (24 inch) telescope at the Piszkéstető station in the Mátra Mountains when an unknown object streaked through a set of his images. It is the 7th such object to be tracked in outer space and then observed to enter our atmosphere. A tiny asteroid the size of 2023 CX1 enters the Earth’s atmosphere about once a month and gives asteroid hunters a chance to practice for a big one.
- Carson Fuls, one of my Catalina Sky Survey teammates, is leading the effort that will allow you to join our NASA funded adventure in asteroid hunting and discovery. You will learn how to scan our nightly archival images to discover new small solar system worlds.Happy asteroid hunting.

I’m Rob Webb, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare. Let’s start by talking about the naked eye planets visible this month, the lunar phases, and then the meteor shower and other events, so you can plan further ahead than me.
Similar to October, in November Saturn and Jupiter are the steady highlights above, Venus shines brilliantly after sunset, and rocks fall from the sky.
A highlight:
17th - 18th – Leonid Meteor Shower – This annual, weak (10-15 per hour) meteor shower can have some wonderful years. This year is good because the waxing crescent Moon will already be set early in the evening, making it clear of lunar light pollution into the morning, the best time to view it.
Some advice for watching:
Find a dark location and lie down in a reclining chair or hammock Look around Leo’s head. That is where the radiant is - where the meteors will appear to be coming from. The strategy to observe this year is to get out there whenever you can, but the later you stay up, the more you’ll see, since the radiant will be higher and you’ll be closer to the peak. Check the weather to see if the skies will be clear Adapt your eyes to the dark by staying away from light sources or using a red light if you need to look at a star chart or not trip over something. You never know when a nice meteor will burn up, to take a nice look at the sky in general, noting that the meteors will appear to go from the radiant in the head of Leo and outward.We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

George’s Random Astronomical Object presents HD 11397. This Sun-like star might seem ordinary, but it actually contains abnormally large amounts of heavy elements, most notably barium, that it could not have formed itself.
Brief biography: Dr. George Bendo is an astronomer who specializes in studying interstellar dust and star formation in nearby galaxies. He currently works at the Jodrell Bank Centre for Astrophysics at the University of Manchester, and his primary role is to support other astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA). He has been creating biweekly episodes of George’s Random Astronomical Object since 2019.

Ralph Wilkins hosts.
Damien Phillips, John Wildridge and Dustin Ruoff produce.
From Oct 21, 2022.
This show is all about Betelgeuse and supernovas (supernovae? Let's call the whole thing off). What will happen to Betelgeuse? How bright will it get? When will it go supernova? Will we get to see it? How do we predict supernovas?
A new study points to a rapid dimming (like the one we saw in 2019!) just before it obliterates itself in a violent release of energy that will make it brighter than anything else in the night sky.

Today's 2 topics:
- Project Breakthrough Listen is spending $100 million over 10 years so that radio telescopes can search for signals which may indicate extraterrestrial intelligence.In a recent article in the Astronomical Journal a team of astronomers published a paper entitled “A 4–8 GHz Galactic Center Search for Periodic Technosignatures”. The teams first effort yielded a null result, however, they plan to continue to search for rotating beacons which could be used by extraterrestrials to communicate with far flung regions of the Milky Way.
- An extremely wide field of view camera, the Zwicky Transient Facility, operated by Caltech on Palomar Mountain in California is able to take images of the entire northern sky every couple of days. This capability has enabled to astronomers to find nearly 8,000, Type IA supernova. A recent discovery SN Zwicky is unique.

Dr. Jarita Holbrook continues with her story of the AAS’ Astronomy Oral History Project.
Dr. Holbrook (Harvard Smithsonian Ctr. for Astrophysics, Univ. of Edinburgh, Univ of the Western Cape) continues with her story of the AAS’ Astronomy Oral History Project. You’ll learn about her favorite interviews, and she gives me some advice for future podcast episodes.
H’ad astra historia is the official podcast for the Historical Astronomy Division of the American Astronomical Society. We’re here to share stories from and about the people who study the stars, planets, and the cosmos. We’ll be hearing from individuals who not only study the history of astronomy, but also those who lived it, who were “in the room” during pivotal events within the last 50 years or so.

When not reading some of her way-too-many books, she watches BritBox, creates recipes, or plays in the garden. She chose science writing/editing in astronomy as a new career. In short, she’s a science-word-nerd-foodie-with-a-plant-habit who really likes the stars.

Robots Like Us...
Implausible Engineering – Episode 2a: Brain in a robot
In a step towards technoevolution and potential immortality that some future generation of humanity will develop the ability to transfer their brains into robot bodies and hence have prolonged if not immortal lives. Various complications arise in trying to engineer this. Assuming you have all the vital veins and arteries attached to tubes which feeds a nutrient solution in and out with some kind of hemoglobin carrier in it that donates oxygen and removes carbon dioxide – all you are really doing is replacing the life support systems previously provided by a human body. But your brain is still a brain.
Implausible Engineering – Episode 2b: Evolving into robots
As we like to discuss on Cheap Astronomy us humans, like the dinosaurs and the trilobites and the blue-green algae are just steps in a meandering evolutionary pathway to nowhere particular. It’s not like the blue-green algae, trilobites or dinosaurs ever aspired to be something better, it’s just that some individuals with certain traits were more successful than others so they had more progeny and so on.

Most of the 5,000 exoplanets discovered so far have been found using methods that don’t actually see the planet at all. Brightness dimmings and star wobbles only get us so far. They limit our ability to study them in detail and astronomers are working on gigantic starshades to resolve planets directly!

Today's 2 topics:
- Atira, named for the Pawnee goddess of Earth and the Morning and Evening Star orbits the Sun inside of our path. Atira, the first of this type of asteroid, was discovered by the Lincoln Near-Earth Asteroid Research Program using telescopes in New Mexico. Atira is a stony object more than a mile in diameter, spins on it's axis of rotation once every three hours, has an irregular shape, and orbits the Sun once every 233 days. This asteroid was named Atira who is a goddess of the Native American Pawnee tribe. She is the wife of the creator god, Tirawa [Tire a wa]. She is the goddess of Earth and the Morning and Evening star.
- Should martian microbes be sacrificed to human space exploration?
It is unlikely that any living organism could survive being blasted from the surface of a planet, travel through interstellar space on a meteoroid, survive a fiery entry through another planet's atmosphere, and be viable when it reaches the surface. However, humans are breaching this interplanetary barrier. We have robots operating and are planning to land colonists on the red planet. This situation has prompted doctoral student Daniel Helman of Prescott College to ask the question "If Martian microbial life is discovered, is it ethical for humans to colonize Mars even if that means spoiling the environment of the microbes?"

From March 1, 2021.
Scientists have been looking for the reclusive neutron star expected to be at the center of supernova 1987A for over thirty years, and they may have finally found it in new images from the Chandra and NuSTAR observatories. Plus, a look at conflicting papers on the object that wiped out the dinosaurs, a roundup of news, and this week’s What’s Up.
