From February 3, 2021.

A radio-loud magnetar first observed in March 2020 suffered an apparent identity crisis, behaving like a pulsar until gradually settling into magnetar-like emissions in July. Plus, Mars’ moon Phobos, Jupiter’s moon Ganymede, and an interview with SETI Institute scientist Veselin Kostov about last week’s sextuple star system.

From Feb 3, 2023.

Nuclear powered rockets are about to become a reality opening up space travel for humanity. Ever since the dawn of nuclear weapons and reactors, advanced militaries and space agencies have dreamt of powering rockets with long lasting energy efficient nuclear fuel.

The Soviet Union and United States ran a number of programs to develop nuclear propulsive power for human spaceflight. Deep space robotic spacecraft, lunar and Mars rovers have all been powered by 'nuclear batteries' in the past - as have experiments that the Apollo astronauts took to the moon - but no nuclear rocket engines have been tested, let alone flown, in space. That is about to change with a NASA/DARPA collaboration to do just that in the hope of cutting the time to travel to Mars by more than half.

Dr. Jamal Mimouni takes us on an astronomy journey through Africa starting with his long-standing, active group in Algeria.

Dr. Mimouni is an Algerian astrophysicist, who received his higher education partly in Algeria (B. Sc. in Theoretical Physics in 1977 from Algiers University) and partly in the States (Ph. D. in Particle Physics in 1985 from the University of Pennsylvania, Philadelphia). He is also an actor on the science, society, and the cultural dimension of the scientific debate in the Arab-Muslim world and has developed a keen interest in the philosophy of contemporary science, as well as to spreading scientific culture in societies of the developing world. 

On the ‘ground’, he has acted as adviser and resource person to amateur astronomy associations in Algeria and is the head of the well-known Sirius Astronomy Association. He has been elected last year as President of the African Astronomical Society (AfAS) based in Cape Town, SA. He has been working closely with the Algerian Ministry of National Education as a scientific adviser, and has conceived and directed various regional training workshops for both elementary school and high school physics teachers: “From Geography to the Cosmos”. Finally, he has authored along with N. Guessoum a popular science book in Arabic “The Story of the Universe: from Early Conceptions to the Big Bang” for an University educated readership, and contributed to an academic collective book “Science and Religion in Islam”.

Mike Simmons is the founder of Astronomy for Equity ( https://bmsis.org/astro4equity/ ). Others on the team, including people around the world in astronomy and space exploration, authors and philosophers, designers and artists and more will be added as the website is developed.

There is an ongoing debate on where NASA should go next with humans: to the Moon or Mars. (Or maybe an asteroid or one of Mars’ moons). We are on the verge of sending humans back to the Moon. At the same time others would prefer we focus our exploration on Mars. It’s a tough choice because there are costs and benefits to both. Let’s try to give this conversation some nuance. Let's discuss the reasons for each of these worlds.

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 February & March 2024.

Today's 2 topics:

- Unlike other space missions which are conducted out in the open the asteroid mining company AstroForge’s first mission to a potentially valuable nearby rocky M type asteroid is being planned in secret so that some other company doesn’t have the chance to grab it before they do.

- My Catalina Sky Survey teammate Alex Gibbs discovered his 31st comet while asteroid hunting in Leo with our 60 inch telescope on Mt. Lemmon, Arizona. It orbits the Sun once every 6 years on a path between Mars and Jupiter. Comet P/2023/Y1 (Gibbs) is one on the 600 plus known members of the Jupiter family of comets.

The Actual Astronomy Podcast episode 474 presents The Skies over the Southern Ocean. In this episode we talk with Micahel Wright who recently visited Australia to view the Southern Skies for the first time. Michael provides a travelog of his trip as well as what he was able to see in the night sky from down under through a 20-inch telescope. Michael paints a picture for listeners through his sketches and explanations as well as a run down for how to plan your own trip. Michael Wright is a visual observer  / Sketcher  from Kitchener-Waterloo area, President of the KW RASC Centre, piano teacher and college instructor.

It's not surprising that there's a lot of interest in the topic of getting a good job in astronomy.  Every time I mention in on our podcast or in a stream., there are lots of responses and questions.

We also live in a time where the value of a college degree is under great scrutiny.  Are they worth the money they cost to get?  Is the value a good return on investment?  What sorts of jobs can one get with a degree versus without one? Let's discuss this on our first Astronomy Coffee Hangout in quite a while.
