The 365 Days of Astronomy 365DaysOfAstronomy.org

From May 22, 2024.
In this episode, we’re taking a closer look at Sunspot complex 3664 and the beautiful chaos that it’s been creating. And because we’re in a planetary science kind of mood, we’re also looking at stories related to observing weather on alien worlds, the history of Mars Climate, and even how solar storms might affect that particular Red Planet.
 
We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

Hosted by Loretta Cannon for the AAS-HAD.
Today’s guest: Dr. Steve Maran (retired from NASA and AAS - https://aas.org/stephen-p-maran) shares stories with us from his almost 70 years working, and having fun, in astronomy.
 
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.

Bio: Loretta Cannon, an AAS affiliate via Rose City Astronomers, is a member of the leadership committee for the Historical Astronomy Division (2023-2025). She is a polymath with degrees in anthropology, microbiology & biochemistry, and has many years of experience in both the private sector and government. 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-and-word-nerd-foodie-with-a-plant-habit who really likes the stars.

What can the anti-matter be?
Dear Cheap Astronomy – How much antimatter is there and will it eventually annihilate?
Antimatter is generally found in subatomic particle form – so there’s antiprotons and anti-
electrons, which can rarely come to together to form an antihydrogen atom. But
that’s about it, an anti-helium nucleus has been created in a laboratory but neither it nor any
other more complex anti-nuclei have been observed in nature.
 
Dear Cheap Astronomy – How fast could we get to Alpha Centauri with current technologies?
If we calculate the trip duration based on speeds achievable with current technology, a mission
to Alpha Centauri, the nearest star system to ours, would take over 6,000 years. But even that is
wildly optimistic when you consider the mass you need to accelerate up to those speeds.

From  Aug 11, 2023.
Hosted by Tony Darnell.
Imagine a planet that is so far away from us that it takes 40 years for its light to reach us. Now imagine that this planet has not one, but two stars that it orbits around. And finally, imagine that this planet has clouds made of sand particles that change the brightness of its atmosphere wildly as they move in the air. 
 
This planet, VHS 1256 b, has recently been observed by the James Webb Space Telescope and it is a very interesting world. It is not like any of the planets in our solar system, or even like most of the planets that we have found outside our solar system. It is a type of planet called a brown dwarf, which is somewhere between a giant gas planet and a small star. Brown dwarfs are very hard to study, because they are very faint and cold compared to stars, and very bright and hot compared to planets.

By Fraser Cain & Dr. Pamela Gay.
Most of the exoplanets we’ve found are around stars, where they belong. But a few have been found free-floating in interstellar space. The evidence is growing that there are a lot of them out there, maybe even more than planets with stars. How do they form and how can we learn more about them?

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 Feb 10 & 17, 2023.
Today's 2 topics:
- The discovery by Greg Leonard of P/2018 VN2 (Leonard), a Jupiter family comet whose fate is to become a garden variety main belt asteroid.
- Comets Travel Between Stars. An interstellar traveler visits our neighborhood on its tour of the Milky Way. Comet Lemmon will continue on a hyperbolic path into deep space. In 2043 it will be further than the average distance that Pluto is from our Sun. Eons from now comet C/2018 U1 (Lemmon) may enter another solar system and be tracked by intelligent beings as it continues its tour of the Milky Way.
