| 6/21/26 |  Travelers in the Night Eps. 891 & 892: 2026 AA & 140 Meter Asteroids | 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 March 2026. Today's 2 topics: - My Catalina Sky Survey teammate Tracie Beuden was observing with our Schmidt telescope on Mt. Bigelow, Arizona in the constellation of Perseus when she found 2026-AA, the first asteroid of 2026. Asteroid hunters are trying to track Tracie's discovery with our number on it far enough in advance so humans could give it a tiny nudge and make it miss Earth. - Humans can mitigate the damage done by the impact of an asteroid given a sufficient lead time. In 1998, the US Congress mandated NASA to detect and track 90% of the 1 km sized asteroids capable of effecting local mass destruction as well as global disruption of agriculture and other human activities. This goal has been accomplished. In 2005 Congress extended the mandate to require NASA to detect and track 90% of the 140-m asteroids capable of destroying a large metropolitan area.

| 6/18/26 |  Actual Astronomy - Telescope Powers | Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan who enjoy teaching astronomy classes and showing the public views through their telescopes. actualastronomy@gmail.com This month we talk about the full range of telescopic magnification powers from Low, Medium to High and how to achieve them using exit pupil. Topics include using exit pupil as a guide to power and how to successfully use high powers. To recap Exit Pupils and Eyepieces: We have High, Medium and Low powers, - Low Power is in the Exit Pupil Range 2-4mm, so on my 180mm f6 that's 12-24mm eyepieces giving 45x-90x - Medium Power is around 1.5mm Exit pupils, so a 9mm for my scope for 120x - High equates to about a 0.5mm Exit pupil which for an F6 scope that would be a 3mm which on my 180mm would give 360x In addition to these we have RFT or very low power for me I use my 40mm and 32mm for 27-35x and Ultra-high which is anything above 0.5mm. Careful in going to low as beyond 6-7mm exit pupils the pupil will cut into the light path. The most favored eyepiece exit pupils are those in the 1.5-3mm range for galaxies, globular clusters. This is where the eye performs best under low light conditions and these magnifications help reduce the sky brightness without reducing the object brightness to the same extent,,,thus making such objects more visible. This is why I use my 17mm, 12.5, 12, 10mm's the most when making observations of these targets. For low power wide field nothing beats the 40mm XW which gives me a 2.5TFOV and 27x and I use my 5mm XW lots on the planets and Moon. Shane do you have any high power eyepieces? What is the highest power you've successfully used? What are some of the challenges with using high powers? My introduction to using high power came by accident. I wanted to buy all the Pentax XW's, while designed for spotting scopes, they work perfectly with eyeglasses and each year Pentax would put some on sale. The 20mm is arguable the dog of the lot, the 14mm is a bit better but the rest are of the highest quality so I ended up with these first but soon a after the 3.5mm went on sale and I thought…well…I'd eventually get it anyway so even if I didn't use it that much it'd be nice to have. Oddly I ended up using it all the time and it is one of my most used eyepieces and not only that but it barlows very well with my 1.6x Nikon creating a 2mm eyepiece. Eventually I acquired the 5mm, 7mm and 10mm and use my 2x and 3x barlows on them. Typically you don't want to exceed the 0.5mm exit pupil size as on planets floaters and other eye issues challenge the observer. So why would I go above this threshold? So wind the clock back to the Nova East Star party in 2003, Mars was at it's closest point to earth in 60,000 years and Tony Jones showed up late at night with his 5-inch Astrophysics APO refractor. We ended up barlowing a 4.8mm Nagler 2x for 430x. The details were amazing. Roy Bishop, who has authored that section on Exit Pupils and Eyepieces for the OH was there, he explained that while no additional detail could be seen past about 300x making the image this large made the details that could be seen larger. I've always enjoyed running high power on Mars and the 3.5mm on my 60mm Tak gives splendid views of Venus in the 100x range. With the 180mm f6 my 3.5mm gives 308x and on steady nights I have used up to 500x. After experimenting I determined the optimal magnification limit is about 430x and that coincides with the actual theoretical limits discussed in many texts and online posts. I found that the Pentax 70-degree AFOV was a bit restrictive and wanted to use my 84-degree Docter. I ran across the SkyWatcher Nomad 5x Telecentric Barlow, Telecentrics don't move the exit pupil around and I have found sometimes SkyWatcher has a few hidden gems…it was only about $100EU and not available in NA so I thought I'd give it shot. It works perfectly, I get 432x and the field of view is excellent! We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

| 6/17/26 |  Cheap Astronomy - Dear CA Ep. 135: Going Nuts | Are we really ready? Hosted by Steve Nerlich. From Dec 1, 2025. Cheap Astronomy tries to stay sane on a trip to Mars? Dear Cheap Astronomy – Will we just go nuts on a two-year mission to Mars Well, we might if the space radiation doesn't kill us first. As we may have noted in previous episodes, current timelines for when we'll land on Mars seem to take little account of the fact that there are many mission components we don't even have conceptual solutions for let alone anything flight-tested or even prototyped. So current aspirations of having footprints on Mars in the 2030s are just aspirations. Dear Cheap Astronomy – Will we just go nuts on a two-year mission to Mars, Part 2 In the last episode, we discussed the mental duress involved in sending a crew of up to five on a two year mission to Mars – which is 7 months each way with an extended stopover in the middle, with the whole experience involving relentless exposure to the risk of imminent death, and where radio delays with Earth may stretch out towards 20 minutes, enhancing the whole experience of isolation and helplessness.

| 6/14/26 |  Travelers in the Night Eps. 889 & 890: Lick Observatory & Comet 467P (Linear-Grauer) | 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 March 2026. Today's 2 topics: - In 1892 the world's largest telescope, the Lick Observatory's 36 inch refracting telescope made the news when E.E. Barnard discovered, Amalthea, the 5th moon of Jupiter. In 2025 this historic telescope made the news again when on Christmas morning winds of 114 mph blew off a 3 ton piece of the shutter on its dome. The adaptive optics research pioneered at Lick Observatory helped in the creation of the twin giant 10 meter telescopes that sit atop Mauna Kea in Hawaii. - Astronomers using the 8.1 m Gemini South Telescope in Chile were excited by the fact that 467P (LINEAR-Grauer)'s Centaur like orbit had been changed as the nucleus emitted rocket like bursts of gases as it was warmed by the Sun. Inert inactive asteroids orbit the Sun following the law of gravity whereas active asteroids can emit little rocket like bursts of gas which can change their path about the Sun in interesting ways. It is important to study objects like 467P (LINEAR-Grauer) to make sure their path about the Sun doesn't change to make them a threat to our home planet.

| 6/13/26 |  NOIRLab - Strong Hints of Magnetic Fields On Exoplanets | Using the Gemini North telescope in Hawai'i and the European Southern Observatory's Very Large Telescope, a team of astronomers measured wind speeds on seven very hot, Jupiter-like exoplanets. The observations revealed that the winds on these planets are most likely governed by magnetic fields, providing the first robust measurement of magnetic activity on planets outside the Solar System. In this podcast, Dr. Hayley Beltz describes how these magnetic fields were discovered from observations using data from the Gemini North telescope in Hawai'i and the European Southern Observatory's Very Large Telescope. Bios: - Rob Sparks is in the Communications, Education and Engagement group at NSF's NOIRLab in Tucson, Arizona. - Dr. Hayley Beltz currently a Postdoctoral Associate at the University of Kansas and an incoming NHFP Sagan Fellow. Her work focuses looking at hot and ultrahot Jupiter atmospheres with three-dimensional atmospheric models and exploring how magnetic effects might change atmospheric circulation and appear observationally. She is also very passionate about teaching and mentoring students.

| 6/7/26 |  Travelers in the Night Eps. 887 & 888: Apophis Bound & Investigating the Mystery of How Life Formed | 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 2026. Today's 2 topics: - In April 2029 on one of the luckiest Friday the 13th in human history the 1,500 ft by 500 ft asteroid Apophis will pass within 23,600 miles of the Earth's surface traveling at some 4.6 mi/s. This is extremely fortunate since an Apophis impact would release the energy of scores of nuclear weapons and cause wide spread devastation. NASA's OSIRIS-APEX will become the companion of the potentially hazardous asteroid Apophis on 5 June 2029. - On Earth living things are everywhere from the deepest ocean depths to the highest mountain tops. On our home planet RNA (Ribonucleic Acid) is a complex essential molecule involved in the process of translating genetic information into the working components of living cells. In a recent paper in the peer reviewed scientific journal Proceedings of the National Academy of Sciences, Dr. Yuta Hirakawa and his team of two coauthors report on their experiments to produce RNA under conditions similar to those which may have occurred in the early history of Earth and Mars.

| 6/4/26 |  Guide To Space - Lunar Rovers, From Apollo to Artemis | https://www.youtube.com/watch?v=larzCw9Vn-w From Jul 21, 2020. When the Apollo astronauts first landed on the Moon, they couldn't go far on foot. That's why the three final missions were equipped with Lunar Roving Vehicles, or Moon buggies, which allowed the astronauts to cover much more ground and do more science. Now that NASA is returning to the Moon by 2024 as part of its Artemis Program, it's considering a fleet of new vehicles that will help astronauts roam far and wide across the surface of the Moon. 60 fps Apollo Videos from Dutchsteammachine: https://www.youtube.com/channel/UCRGEIYuo_HbUR6GhFLeEkPA We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

| 5/31/26 |  Travelers in the Night Eps. 885 & 886: Dark Sky Network & Aviation and Space Weather | 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 2026. Today's 2 topics: - Around the world those who value the natural night sky are evaluating the effects of light pollution. In addition to impairing astronomy and star gazing the past 100 years of increasing light pollution is proving to be harmful to human health and the natural world upon which we all depend. The purpose of the Dark Sky Network is monitor and facilitate the mitigation of the harmful effects of light pollution. - The Earth's atmosphere does a good job of protecting humanity from space weather, however, occasionally a major event does break through our shield and gets our attention. Tree rings and ice cores have recorded past space weather events thousands of time larger than which have occurred in the modern age. Investing in research seems wise.

| 5/30/26 |  UNAWE Space Scoop - Story Of the Sun's 'Road Trip' Through the Milky Way With Friends | https://spacescoop.org/en/scoops/2605/story-of-suns-road-trip-through-the-milky-way-with-friends/ Did you know that our Sun and its many, uh, childhood friends were all born at a place much closer to the center of our Galaxy? Over the years, our Sun and its friends have been on sort of a speedy galactic tour traveling a distance of almost 10,000 light-years from the center of the Milky Way. But traveling much farther than that on a long curved trajectory! Astronomers call this the 'mass migration' of stars. Kind of like a flock of migrating birds. How and when did these stellar siblings migrate to where they are now? To find out, a team of astronomers did some galactic archaeology, tracing the history of stars in our Galaxy. Using data from ESA's Gaia telescope, the team found almost 6,600 stars just like our Sun. The astronomers aptly call these stars the 'solar twins.'

| 5/28/26 |  H'ad astra historia - Ep. 303: A Review of This Month in Astronomical History | Today's 'guest' is HAD's This Month in Astronomical History. I'll be reading two essays from the archives: Dr. Rebecca Charbonneau's Aug 2018 essay titled, "The Mysterious Wow! Signal" and Dr. Richard Fienberg's May 2022 essay titled, "The First Telescope on the Moon." This Month in Astronomical History is a lead-in to next month's interview with the new Editor, Dr. Mugdha Polimera. 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. podcast theme music: "Frost Waltz" Kevin MacLeod (incompetech.com), licensed under creative commons: by attribution 4.0 license (http://creativecommons.org/licenses/by/4.0/) Podcaster: Loretta Cannon (an AAS affiliate via Rose City Astronomers) is a science-and-word-nerd who really likes outer space and the people who study it.
