    Astronomy Cast Ep. 118: Sky Surveys

    http://www.astronomycast.com/archive/ From December 12, 2008. Hosted by: Fraser Cain (@frasercain) and Dr. Pamela L. Gay (@CosmoQuest) In the old days, astronomers had to beg for telescope time. They'd put together a proposal, convince observatories to gather data for them, crunch that data and release the results. No telescope, no results. But everything's different now. Fleets of robotic telescopes constantly scan the skies, building up a vast database of raw data about the Universe. Anyone who wants can access the information through the Internet, download what they need to do real science. No telescope necessary. Let's look at the development of sky surveys, and how they're changing how astronomy gets done.   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!

    Travelers in the Night Eps. 367 & 368: Moons of Florence & Roving Venus

    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 December 2025. Today's 2 topics: - Dr. Lance Benner of NASA's Jet Propulsion Laboratory headed up a team of scientists who used the 70 meter antenna at NASA's Goldstone Deep Space Communications Complex to bounce RADAR beams off of the asteroid Florence as it made a close approach to Earth in September of 2017. The RADAR images these researchers obtained reveal that Florence consists of a 2.8 mile diameter primary asteroid which is orbited by two small moons.   - Venus and Earth are similar in size, composition, density, and mass. Unfortunately, our sister planet Venus is an example of a place where green house gases have created an extreme situation. Venus's thick carbon dioxide atmosphere has a surface pressure 90 times that of Earth. It would crush a submarine. Additionally, the thick atmospheric blanket holds in the heat causing Venus's surface temperature to be 864 F, hot enough to melt lead.   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!

    EVSN - After Hours: International Moon Day 2026 With guest Jekan Thanga

    Hosted by: Dr. Pamela L. Gay (@CosmoQuest) From July 22, 2026. On July 20, the world celebrates International Moon Day. This UN designated holiday marks the anniversary of humanity's first landing on the Moon. The Apollo 11 landing in 1969 is now only a distant memory or a date from history for most people, but it is worth thinking about as the world prepares to return humans to the Moon in the coming decade. Joining us to discuss International Moon Day is Dr. Jekan Thanga, the head of the Space TREx Laboratory at the University of Arizona. Come learn how his interdiciplinary team is taking a page from the past as we plan for a Lunar future.   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!

    Guide To Space - Where Do Comets Come From? Exploring the Oort Cloud

    https://www.youtube.com/watch?v=IQtdQ94jy8I From Oct 17, 2017. Hosted by: Fraser Cain (@frasercain) Some comets orbit the Sun on a regular basis, but others come in from deep space, a region known as the Oort Cloud. What causes them to make this journey, and will we ever be able to explore the Oort Cloud?   Before I get into this episode, I want to remind everyone that it's been several decades since I've been able to enjoy a bright comet in the night sky. I've seen mind blowing auroras, and witnessed a total solar eclipse with my own eyeballs. The Universe needs to deliver this bright comet for me, and it needs to do it soon.   [Editor's note: Rich here. I'm spoiled by comet Hyakutake.]   By recording this video now, I will summon it. I will create a video that'll be hilariously out of date in a few months, when that bright comet shows up.   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!

    Cheap Astronomy - Dear CA Ep. 137: Space Missions

    Hosted by Steve Nerlich. We are still out there. Dear Cheap Astronomy – Why do some space missions last so long? So, we're all familiar with the stories of the Mars rovers, Spirit and Opportunity, landing with mission lifespans of 90 days, that then went on to rove the surface of Mars for 15 years. And the Voyager probes, launched in 1977, were supposed to have five-year missions, which are now going on 47 years and counting. So, what's going on? Is NASA just crap at predicting mission lifetimes?   Dear Cheap Astronomy – How much faster is nuclear thermal propulsion? The idea behind nuclear thermal propulsion or NTP is that you have a nuclear fission core, which is probably uranium-based. This can generate a lot of heat over long periods and you then feed in a propellant that will expand on heating, for example liquid hydrogen. The expanded gas then shoots out a rocket nozzle and pushes your spacecraft forward on the basis of Newton's actions produce opposite reactions.   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 Cast Ep. 160: Eclipses

    http://www.astronomycast.com/archive/ From October 19, 2009. Hosted by: Fraser Cain (@frasercain) and Dr. Pamela L. Gay (@CosmoQuest) Every now and then, the Moon destroys the Sun. Okay, not destroys, covers. Well, not really covers, but from here on Earth, sitting inside the shadow of the Moon, that's what it sure looks like. These events are called eclipses, or more precisely, transits and occultations. They occur whenever one object passes in front of another from a 3rd perspective. They're beautiful and exciting, and deliver a tremendous amount of science as well.   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!
