Awesome Astronomy - We've Discovered At Least 5,000 Planets!
Ralph Wilkins and Dr. Jenifer “Dr. Dust” Millard host. Damien Phillips, John Wildridge and Dustin Ruoff produce. From Jan 28, 2022. Taking a look at how over the last 40 years we went from only knowing of the handful of planets in our solar system to knowing of around 5,000 planets littering the galaxy. How have we discovered new planets? How many are there? How many stars have planets around them? Are there star systems with multiple planets like our solar system? Do we see the diversity of large gassy, small rocky and ringed planets around other stars? And the big one - are any of them habitable? Find out in this episode!

Astronomy Cast Ep. 758: Non-Roving Rovers
Streamed live on May 26, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay Some of our favorite robots are rovers currently roving around the surface of the Moon & Mars. But there’s some pretty tricky terrain out there and engineers are scheming up clever ways to explore other worlds inspired by life that crawls, slithers, hops and flies. As we explore more surfaces and more complex surfaces throughout the solar system, mission teams are designing robot explorers that don't sit still and also don't rove. In this episode, we're going to take a look at the new technologies that are allowing technology to get around. SUPPORTED BY YOU This Episode is made possible thanks to our Patrons on Patreon.

From January 2017 & August 2024. Today's 2 topics: - 2017 will be (was) a good year to view comets with your unaided eye or a pair of binoculars. - My Catalina Sky Survey teammate Richard Kowalski was surprised to find a moving point of light on some his images which was more than 50 times brighter than a typical Earth approaching object he observes. He was even more amazed when it was not cataloged as a known object and he reported his observations to the Minor Planet Center.

UNAWE Space Scoop - Could This Be One of the Strangest Planets Ever Found?

UNAWE Space Scoop - Could This Be One of the Strangest Planets Ever Found?
Recently, a team of astronomers found a new exoplanet, called 2M1510 (AB) b, that really surprised them. This new exoplanet is special — its orbit looks more like a Ferris wheel! It goes up and over the top rather than around the side, traveling at a right angle to the carousel-like path we normally find. But having an unusual orbit is only part of the puzzle, and to see just how odd our new exoplanet is we also need to look at its stars.

EVSN - A Failing Look at Earth, a First Look at Other Worlds, & More
From May 19, 2025. In this week’s closer look we are going to look at the earth-facing missions that are getting dragged down by our atmosphere and will be forcibly retired by physics in the next few years, again with no replacements in the works. These missions allow us to do long term monitoring of our planet, its atmosphere, and the variables that help us understand everything from weather to climate change. We also look at cool new exoplanet discoveries, the beautiful death of a star, and tales from the launch pad.

Cheap Astronomy - Dear CA Ep. 118: Reflections

Cheap Astronomy - Dear CA Ep. 118: Reflections
Self-consciousness. Dear Cheap Astronomy – Selfies in space. Buzz Aldrin claims to have taken the first selfie in space in 1966, where he fixed a Hasselblad camera on the hull on Gemini 12 and then leant back before triggering the camera. Later on, in 1969, Neil Armstrong took an accidental selfie – the only still photo of him on the Moon where he and his camera are reflected in Buzz Aldrin’s visor. Dear Cheap Astronomy – Is Hawking Radiation real? Long-term listeners are probably familiar with Cheap Astronomy’s tendency to go a bit ranty in the face of any unreasonable acceptance of cosmology hypotheses. So, for example, the Universe is not only expanding but that expansion is accelerating. Sounds extraordinary, but there’s sound observational evidence to back it up.

Exoplanet Radio - Biosignatures: The Search for Life Beyond Earth

Exoplanet Radio - Biosignatures: The Search for Life Beyond Earth
From September 20, 2023. Hosted by Tony Darnell. Episode 39. In recent years, scientists have made great strides in the search for extraterrestrial life. They have discovered thousands of exoplanets. And some of them are located in the habitable zone of their star, which means that liquid water could exist on their surface and is essential for life as we know it. The search for life however, is a little more involved than finding planets, measuring their location and distance around the star and figuring out their location within a habitable zone. Astronomers need more information to learn if life may be there. We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.

Astronomy Cast Ep. 757: CubeSats
Hosted by: Fraser Cain and Dr. Pamela L. Gay Streamed live on May 19, 2025. Computers are getting smaller, faster and more capable, which has enabled an entirely mew class of satellites: CubeSats. A mission small enough that you can hold it in your hands, and yet powerful enough to even travel to other planets and send messages home. Every year, our electronics seem to get smaller and more powerful, with today's smart watches being more fully featured than the computers Pamela and Fraser had as little kids. These tiny processors, sensors, and transmitters are allowing tiny satellites with powerful functionality, and today we take a look at how this is changing space exploration.

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. From May, 2024. Today's 2 topics: - Comet 12P/Pons-Brooks comes near the Sun once every 71 years. It was discovered in 1812 by Jean Louis Pons at Marseilles, France and then rediscovered by American Astronomer William Robert Brooks in 1883. Electronic cameras reveal this comet's nucleus has jets of gas that produce a spiral structure not unlike water jets from a lawn sprinkler. - On the 3rd of March 2024 while asteroid hunting with our 60 inch telescope on Mt. Lemmon , Arizona my Catalina Sky Survey teammate Kacper Wierzchoś discovered a comet moving through the constellation of Draco.Since we don’t know Kacper’s comet’s chemical composition it is impossible to accurately predict how. bright it will be as it crosses the Earth’s orbit December 12, 2025, rounds the sun January 20, 2026, and crosses our orbit again February 27, 2026.

Guide to Space - What Has The Curiosity Rover Discovered? A Collaboration With Joe Scott
From Feb 20, 2018. All Hail Curiosity! Consider the fact that right now, there’s an SUV-sized rover crawling around the surface of Mars, zapping rocks with its laser, scooping and sampling material, and generally giving us the best view we’ve ever seen from the surface of the Red Planet. NASA’s Curiosity Rover has been on the surface of Mars since 2012, following the story of water. When did it first show up on Mars, and was it there long enough to support the biology of life? In its 5 years and counting of exploration, Curiosity has pushed our understanding of the Red Planet forward, and paved the way for the next generation of gigantic, nuclear powered rovers headed to Mars to search for life itself.

Fortunately the closest 2006 HZ51 will come to our home planet is June 11 of 2116 when it will pass us harmlessly 26 times the distance to our moon away from us. - Recently my Catalina Sky Survey teammate Vivian Carjaval was asteroid hunting in the constellation of Ursa Minor with our Schmidt telescope on Mt. Bigelow when she discovered, 2024 BR4, a two football field diameter Earth approaching asteroid.Vivian’s Apollo asteroid discovery poses no threat to humans since 2024 is as close as it will come to Earth in the next few hundred years.

EVSN - Iceland Has a New Volcanic Fissure Erupting in Fagradalsfjall
From March 30, 2021. After much “will it / won’t it” over the last few weeks in the wake of increased (and then decreased) seismic activity, an eruption in Iceland finally started with a brand new fissure near Fagradalsfjall. No lives are threatened, so Pamela is ecstatic. Plus, arctic methane, a new basalt type, spiders on Mars, Titan’s atmosphere, and an interview with PSI scientists Dr. Nick Castle and Dr. Georgiana Kramer about volcanoes.

Actual Astronomy - Affordable Wide Field with Brian Ventrudo
Hosted by Chris Beckett & Shane Ludtke, two amateur astronomers in Saskatchewan. Episode 483! Today we have a returning Special Guest, though it’s been a while. Dr. Brian Ventrudo is author the Cosmic Pursuits web page and a contributing editor for S&T. He has a Ph.D in Laser Spectroscopy and helped measure the fingerprints of the molecules found in interstellar space and planetary atmosphere. In an email Brian mentioned the TV NP127 being a dream scope…which is remaining just a dream for the time being. But why is the NP 127 such a fantastic design? - Fast, flat field, reasonably portable etc. - What have you configured on the cheap? 120mm, mount eyepieces etc. - Wide field eyepieces and the TS Flat2? Field curvature. - My love from 80mm f5 to apo to giant achromats. - 80% or more of my observing is not the 5 objects that show color, Moon, M, V, J, S - Binoculars, budget 80mm/102mm ED refractors, lower-cost eyepieces, mounts and so forth. - Wide Field Objects to Observe: Multiple objects in the same field, whether it’s just the Moon and a planet in binoculars or the Sword of Orion in winter or the Lagoon & Trifid regions and star clouds of summer, Kemble’s Cascade and NGC 1502.

Guide to Space - What If We Do Find Aliens? How Prepared Is Earth For Meeting Extraterrestrials?
From Nov 24, 2016. We've been so busy wondering how we'll find aliens that we never stopped to consider what we'll do if we actually encounter them. How does an alien discovery get communicated to the media? Who's responsible to craft a response?

Astronomy Cast Ep. 755: Intermediate Mass Black Holes
Streamed live on May 5, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay. There are stellar-mass and supermassive black holes. But very little evidence of anything in between. Where are all the intermediate-mass black holes that should be the building blocks of the biggest ones? Actually, the science has been accelerating rapidly and we now know of hundreds of them. The question marks in our understanding are slowly getting replaced with data. Let's review what we now know about intermediate mass black holes and their origins. SUPPORTED BY YOU!

Travelers in the Night Eps. 791 & 792: A Fireball and Its Gifts & Closest Approaching Comet
Dr. Al Grauer hosts. Dr. Albert D. Grauer ( ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. From April 2024. Today's 2 topics: - It all started when Krisztián Sárneczky at the Konkoly Observatory near Budapest, Hungary reported the position and brightness of an unknown asteroid rapidly moving through the constellation of Lynx. Three hours later , the object, now called 2024 BX1 exploded harmlessly in our atmosphere. - P/1999 J6 (SOHO) was discovered 10 May 1995 by Mike Oates as part of the Citizen Science Sun Grazer Project in which volunteers from all over the world have the chance to discover a comet in images taken by the Solar and Heliospheric Observatory or SOHO for short.RADAR studies of the daytime Arietid ( AIR-ee-uh-tids) meteor shower stream which peaks every June 7 indicates that P/1999 J6 (SOHO) could be one of the potential parent objects.

Cheap Astronomy - Dear Cheap Astro #117: The Dark Side

Cheap Astronomy - Dear Cheap Astro #117: The Dark Side
Hosted by Steve Nerlich. Stumbling around in the dark again. What is the latest on dark matter? Well, there’s not much new to report here. The nature and composition of dark matter remains unknown, but the likelihood that there is vast amount of non-interacting, invisible and gravity-inducingly material remains high. Are black holes the source of dark energy? To give you the full story, someone sent a link to an article that claims that black holes are the source of dark energy, along with their actual question which was 'this is just bollocks isn't it’? And yes, it would seem so. Firstly, to properly unravel the story, we should start by acknowledging that Cheap Astronomy thinks the whole dark energy concept is a bit meh.
