The 365 Days of Astronomy

From May 18, 2021. Two new studies are attempting to solve a couple of big puzzles in astrophysics: Is the Hubble constant actually constant? And why do galaxies have flat rotation curves? Plus, a young star’s circumstellar disk, the search for stellar-mass black holes, magnesium in the deep waters of Neptune and Uranus, and an interview with PSI scientist David Horvath regarding possibly active volcanism on Mars.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

https://www.youtube.com/watch?v=xapsn6-9sDU From  Jan 23, 2018. The internet. It gives us an instant connection to the sum of human knowledge, but it also lets misinformation travel at the speed of light. Everyday I get comments about how people will believe we’ve been to space after I show them evidence of actual spacecraft taken in space and not CGI mock-ups.   Challenge accepted. Here come a whole bunch of photos of spacecraft taken in space. Actually, I don’t really care if you believe it or not. I was just so excited about some of the fantastic pictures of spacecraft - taken by spacecraft - that I decided to dedicate a whole episode to it.   Sign up to my weekly email newsletter: https://www.universetoday.com/newsletter   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

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: - More than 400 years ago Galileo Galilei expanded human vision using a telescope to view the cosmos. Since then humans have extended their senses to view the Universe in x-rays, ultraviolet, infrared, radio, and other portions of the electromagnetic spectrum not accessible to our senses. In a pioneering effort, Ekaterina Smirnova has employed the spectroscopy, magnetometry, and molecular data collected by the Rosetta spacecraft to create watercolor paintings, sculptures, a musical collaboration, and an augmented reality project to create new art forms. - My Catalina Sky Survey teammate Rose Matheny had no way of knowing that the fast moving point of light that she had just discovered would create such a stir. Rose sent in her discovery and followup observations to the Minor Planet Center where astronomers calculated that her discovery would make a very close approach to Earth about two days later and gave it the name 2016 RB1. More than two dozen observatories around the world tracked 2016 RB1 as it came towards us.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Kilonova form when two neutron stars collide. They were first discovered by their gravitational wave emissions. In this podcast, NOIRLab’s Dr. André-Nicolas Chene described the discovery of a system that will become a kilonova in the future.   Bios:  Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab in Tucson, Arizona.. André-Nicolas Chene is an associate astronomer at NOIRLab. He completed his PhD at the Université de Montréal in 2007 and learned everything about the fundamentals of astronomical observations at the Observatoire du Mont Mégantic. He was research fellow at the NRC Herzberg Astronomy and Astrophysics Research Centre and postdoc jointly at the Universidad de Concepción and the Universidad de Valparaíso before joining the Gemini Observatory (now a program of NOIRLab) in 2013. For almost 10 years, André-Nicolas took part in every phase of a Gemini observing program life cycle and has played a central role in Gemini's user support effort. André-Nicolas’s research interests are massive stars, hot winds, star clusters, and stellar evolution.   Links:  NOIRLab Press Release: https://noirlab.edu/public/news/noirlab2303/ https://www.cnn.com/2023/02/01/world/supernova-rare-star-pair-scn/index.html https://www.reuters.com/lifestyle/science/astronomers-document-not-so-super-supernova-milky-way-2023-02-01/   NOIRLab social media channels can be found at: https://www.facebook.com/NOIRLabAstro https://twitter.com/NOIRLabAstro https://www.instagram.com/noirlabastro/ https://www.youtube.com/noirlabastro   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Things that orbit the Sun and clear their orbits. Dear Cheap Astronomy – What happens when worlds collide? The outcome of a collision between two planets depends on the speed of the collision, the angle of the collision and the relative masses of the two bodies and their composition – think rocky planets versus gas giants for example. A small planet approaching a large planet slowly might get tidally stretched and break up into pieces, but a fast moving one might impact before there’s been time for gravitational stretching to break it up.   Dear Cheap Astronomy – Why is Mars’ sky red? A good place to start is to think about the colours we are familiar with in Earth’s sky. In the middle of the day, the overhead Sun is a bright white disk you can’t look at directly and the rest of the sky is blue. This is because most of the visible light from the Sun passes straight through the atmosphere, which is transparent to those wavelengths, except at the very short end – so rather than passing straight through, photons in the blue and violet parts of the visible spectrum are scattered – meaning they are deflected off their straight line path and bounce around a lot, although most eventually reach the ground.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

From August 23, 2023. Astronomers estimate that there are more free roaming planets in our galaxy than there are planets in orbit around stars. In fact, rogue exoplanets - planets with no star whatsoever - far outnumber all other planets in our galaxy, by 20 times. Trillions of worlds wandering alone.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

http://www.astronomycast.com/archive/ Trillions of neutrinos are produced in our Sun through its nuclear reactions. These particles stream out at nearly the speed of light, and pass right through any matter they encounter. In fact, there are billions of them passing through your body right now. Learn how this elusive particle was first theorized and finally discovered. I don’t want to alarm the listeners but there is a flurry of particles from the Sun passing through each and every one of you right now. A lot of particles. In fact, there are 50 billion solar neutrinos passing through every one of us every second. Don’t worry, you can’t feel them; they barely interact with matter, but that’s what makes them interesting.

What is gracing the September 2024 skies?  A juuuuust barely partial lunar eclipse, the best viewing for Saturn, 5 lunar close encounters, and the transition to fall. Hi everybody, I’m Rob Webb, your Last Minute Astronomer, bringing astronomy to normies and nerds, with little time to spare.   We’ll start by talking about September’s big events, then highlight the naked eye planets, and finish up with the lunar phases, so you can plan ahead better than me.   7th – 8th – Opposition of Saturn – Saturn, Earth, and the Sun are essentially lined up, causing Saturn to rise at sunset, and set at sunrise, with best viewing around midnight.   17th - Just Barely Partial Lunar Eclipse - The Moon passes into the shadow that Earth is casting into the solar system, but only a little.  Times here are Eastern Daylight, so adjust for your location, assuming you are in the Americas, Africa, or Europe.  The penumbral stage will be almost not noticeable, however the hour of partiality will be.  At 10:12pm the Moon will start to graze the dark inner portion of the Earth’s shadow called the umbra.  About half an hour later it’ll be at maximum eclipse, with 8% of it covered up.  Another half hour later, the dark shadow will no longer be noticeable, and the moon will be in the penumbra until 12:47am. 8:41pm - Penumbral Eclipse Starts 10:12pm - Partiality Starts 10:44pm - Maximum Eclipse (8%) 11:15pm - Partiality Ends 12:47pm - Penumbral Eclipse Ends   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

From November 16, 2021. After five years of observations, researchers have found that the quasi-satellite Kamo’oalewa, which currently orbits the Earth, is similar to a lunar sample collected during the Apollo 14 mission. Plus, Russia blows up a satellite, TESS finds a circumbinary planet, and we interview Dr. Gail Christeson of the University of Texas, Austin, about mapping Chicxulub crater.   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. actualastronomy@gmail.com The September 2024 Observer’s Calendar on Episode 446  of the Actual Astronomy podcast. I’m Chris and joining me is Shane. We are amateur astronomers who love looking up at the night sky and this podcast is for everyone who enjoys going out under the stars.   * Sept 1 - Zodiacal light becomes visible this month    (Mercury is also paired with the Moon in morning, but might be tough) * Sept 3 - New Moon * Sept 5 - Mercury at Greatest Elongation 18-degrees from Sun in Morning Sky * Sept  8 - Saturn at Opposition    * Mars 0.9 degrees from OC M35 after midnight * Sept  9 - Mercury 0.5 degrees North of Regulus in morning sky * Sept 10 - Antares Occultation by the Moon for places like Australia and Indonesia * Sept 11 - First Quarter Moon * Sept 17 - Saturn Occulted by the Moon - Visible barely here just about 5:30am so you want to ideally be west of the Saskatchewan/Alberta Border…straight through NA. * Sept 18 - Partial Lunar Eclipse - Best visible from Brazil and region but most of Eastern NA and Western Europe and Africa    * It is a small partial..just a little chunk goes through the Umbra    * BUT YOU SHOULD GO LOOK    * BECAUSE    * At 1:15 am Saskatchewan Time…so that’s 3:15 am EDT the Moon Occults Neptune for most of us in NA except southeastern reaches of USA. * Sept 21 - Neptune at Opposition * Sept 22 - Equinox       (Moon 0.2-degrees from Pleiades) * Sept 25 - last quarter Moon   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

Astronomy 101 - Everything you need to know about asteroids! - What are they? - What are they made of? - Where are they??   Dr. Jen tells us how we understand so much about these small(ish) objects far away in the Asteroid Belt. Is the asteroid Belt really like the sci-fi depictions and are there other places in the solar system where these fragments of the early solar system roam? And no talk on asteroids would be complete without considering the threat to Earth (and all life on Earth) from them...   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!

http://www.astronomycast.com/archive/ From July 7, 2008. And now we reach the third part of our trilogy on the human exploration and colonization of Mars. Humans will inevitably tire of living underground, and will want to stretch their legs, and fill their lungs with fresh air.

What technologies would be used, and what’s the best we can hope for?   We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.  Just visit: https://www.patreon.com/365DaysOfAstronomy and donate as much as you can!
