Finally, a big update. Have there been news in the realm of exoplanets? More news that we can possibly cover. But we’ll try our best.
Ep 490: What's New with Supernovae
Time for another update, this time we’re going to look at what’s new with supernovae. And once again, we’ve got good news, lots of new stuff to report.
Ep 489: Black Hole Update
Another update episode, this time we look at what’s new and changed in the research of black holes. And it’s here that we find a lot of substantial new discoveries in the field, so much has been discovered since we first covered black holes a decade ago.
Ep 483: Stopping in Space
It’s one thing to get from Earth to space, but sometimes you want to do the opposite. You want to get into orbit or touch down gently on the surface of a planet and explore it. How do spacecraft stop? And what does that even mean when everything is orbiting?
Astronomy Cast Special: Q & A with Dr. Pamela Gay
Pamela will be on to answer your space and astronomy questions live, as Fraser enjoys auroras in Iceland this week!
Ep. 478: Apollo 8 with Paul Hildebrandt
On Christmas Day, 1968 Frank Borman, James Lovell and William Anders became the first human being to see the far side of the Moon. Their mission, of course, was Apollo 8, the first time human beings had ever left Earth orbit and seen the far side of the Moon. Today we talk all about Apollo 8, with special guest Paul Hildebrandt, director of a new documentary about the mission.
Ep. 477: State of Exploration: Once and Future Moon
It’s been decades since humans set foot on the Moon. Well, it’s time to go back, in theory. Of course, we’ve heard this all before. What are the plans afoot to send humans back to the Moon this time. What hardware will we use, and what other strategies are in the works to make this happen?
Updated Audio: Ep. 475: Fast Radio Bursts
Ep 475 fixed audio version – You know what’s fun? Mysteries. Here’s one: fast radio bursts. Astronomers have been detecting mysterious one-time signals from across the sky. What’s causing them? Nobody knows for sure, but the search is on to get to the bottom of them.
Ep. 476: The Overview Effect
After they’ve been to space, many astronauts report that seeing the world from above has given them a totally new perspective on humanity and the state of our planet. It’s called the Overview Effect. Today we’ll talk about this, and what this perspective can teach us all.
We Can Use Your Help!
We are asking for your input through a series of three surveys, each of which is targeting a specific aspect of CosmoQuest and what we do.

Ep. 474: Predictions for 2018
Phew, 2018, time to press the reset button and enjoy a whole new year of space exploration and space science. What’s coming up this year? What should we expect to launch, and what will we see in the sky?
Ep. 473: Remembering the Best Space Science of 2017
2017 was a crazy year for, well, you know. But, it was a great year for space science, a kilonova, extrasolar planets, reusable rockets and more. Let’s look back at the year that was and remember our favorite space science.
Ep. 468: Simulations for Science and Fun
Astronomers depend on simulations to study the Universe. From relatively straightforward orbital simulations to vast simulations that try to recreate the large scale structure of the Universe from the Big Bang. Today we’re going to talk about some of those simulations, as well as tools you can use simulate the Universe.
Ep. 467: Resonance
Many of the moons and planets across the Universe are in resonance with each other and their star. What causes this resonance, and how can it help us understand the history of planetary formation and migration?
Ep. 464: Why the Hype over an Exorock?
Astronomers this week announced that they had discovered an asteroid or comet on a trajectory that brought it from outside the Solar System? Is this the first case of an object from deep space? And what can we learn from this discovery?
Ep. 463: Pareidolia and the Moon
Have you seen the “Man in the Moon”? Pareidolia is your mind’s way of helping you make sense of the world, but doesn’t always match reality.
Ep. 460: Earth from Afar: Remote Sensing
The space age has given us the ability to look at every corner of the globe in every wavelength. It’s revolutionized our ability to predict the weather, keep track of environmental damage, and watch the world change. Today we look at what missions and technologies give us the ability to watch our world from afar.
Ep. 459: Arecibo Observatory
The iconic Arecibo Radio Observatory has been a mainstay in science and science fiction. This Puerto Rico-based radio telescope was already in an uncertain level of funding. But now with the damage from Hurricane Maria, it might be shut down forever.
Ep. 457: Why Did Cassini Have To Die? In Memoriam
It’s time to say goodbye to an old friend, NASA’s Cassini spacecraft, which has been orbiting within the Saturnian system since 2004. But why does a seemingly healthy spacecraft and mission need to come to an end? Today we look back at the mission, some of the amazing discoveries, and why its finale was necessary.
Ep. 456: Pluto Revisited
This week, we return to our starting point, where Astronomy Cast began: Pluto. 11 years on, we have a whole new appreciate for the dwarf planet Pluto. We’ve visited it, probed it and taken pictures. It’s time for an update.
Ep. 455: Your Practical Guide to Colonizing the Milky Way!
This episode was recorded live in St. Louis, MO at the Astronomy Cast Solar Eclipse Escape 2017. Listen as we discuss how humans might be able to colonize the Milky Way!
Astronomy Cast Extra! Solar Eclipse 101
This is a special recording of Astronomy Cast to prepare for the Eclipse, recorded live in St. Louis, MO at the Astronomy Cast Solar Eclipse Escape 2017. We’re going to give you a set of last minute tips and info to prepare for the Great American Eclipse!
