Episode 1: Were the Planets Always in the Same Order?
Air Date: January 4th, 2017
Summary: Four rocky inner planets and four gaseous outer planets - makes sense, right? But when astronomers turned their eyes to planets beyond our star system they found out that many systems are set up differently. Why?
Episode 46: The Hottest Planet Ever
Air Date: June 10th, 2017
Summary: NASA is launching a mission to send a probe into the sun, and it's the first to be named after a living scientist - Eugene Parker and the Parker Solar Probe! Astronomers have found another hot topic, and it's the hottest planet we've ever seen at 4300°C!
Episode 53: How Vera Rubin Found the First Direct Evidence for Dark Matter | Great Minds
Air Date: July 5th, 2017
Summary: Vera Rubin graphed the rotation curves of galaxies, helping astronomers better understand the accelerated orbits of stars on the outskirts of galaxies. Her life's work generated some of the first solid evidence for dark matter in the universe.
Episode 54: The Mysterious Origins of Our Galaxy's Fastest Stars
Air Date: July 8th, 2017
Summary: A new paper that borrows old astrological data from the Voyager 2 probe has used brand-new computer simulations to find some new weird data about Uranus’s magnetic field. Another paper has new information about our galaxy’s fastest stars, called hypervelocity stars.
Episode 55: Do Any Stars NOT Have Planets?
Air Date: July 12nd, 2017
Summary: Astronomers have used a few different methods to detect exoplanets, and improved telescopes are increasing the rate of discovery. But is it possible that any stars DON'T have planets, or are they just an expected feature of stellar formation?
Episode 56: The Coolest Things We Didn't Know About Pluto Two Years Ago
Air Date: July 15th, 2017
Summary: On July 14, 2015, New Horizons flew by Pluto. Scientists have used the data from the mission so far to uncover active geology, an enormous canyon, a unique case of chemical coloration, and more. What else might we discover as we venture deeper into the Kuiper Belt?
Episode 62: Our Alarmingly Close Shave with an Asteroid
Air Date: August 5th, 2017
Summary: How often do we miss asteroids like 2017 OO1, and what are astronomers doing to limit their impact? Meanwhile, distant icy worlds might not look as promising in our search for extraterrestrial life as scientists once thought.
Episode 73: The Curiosity Rover's Most Amazing Discoveries
Air Date: September 13rd, 2017
Summary: It might feel like it was only yesterday that the Curiosity rover touched down on Mars, but in August, the rover celebrated its fifth birthday! For a kindergartener, it’s made some really impressive discoveries.
Episode 75: That Time We Gave Earth a Ring Made of Millions of Tiny Needles
Air Date: September 20th, 2017
Summary: In the 1960s, the USA almost put a ring around the Earth by launching hundreds of millions of tiny copper needles into space in an attempt to create a reliable boost for their communications systems.
Episode 76: The Fiery, Pitch-Black Egg-Planet
Air Date: September 23rd, 2017
Summary: Last week, the Cassini probe dove into Saturn, never to be heard from again, but thankfully, Cassini wasn’t the only probe out there. And we’ve also found an exoplanet that might be even darker and stranger than we thought.
Episode 79: How We Used the Moon to Send Radio Messages
Air Date: October 4th, 2017
Summary: In the early days of the Cold War, it was difficult to send and receive messages across the globe. Before the US launched its first satellite in January 1958, the military tried a creative solution - bouncing radio waves off the Moon.
Episode 80: Mars Cities and Moon Bases - SpaceX's Big New Plans
Air Date: October 7th, 2017
Summary: SpaceX CEO Elon Musk announced some ambitious plans at the International Aeronautical Congress. If he's right, we could have humans living on the moon and Mars within a decade, and you might never have an 18 hour flight again!
Episode 81: What Movies Get Wrong About Space
Air Date: October 11st, 2017
Summary: Hollywood can be pretty negligent about physics and astronomy, even in really good movies, but there are a few specific misconceptions that pop up again and again.
Movies mentioned (and potentially spoiled) in this video - Armageddon, Star Trek (2009), Total Recall (1990), 2001 - A Space Odyssey (1968)
Episode 94: Maybe There Isn't Liquid Water on Mars
Air Date: November 25th, 2017
Summary: Two years ago we were very excited about the announcement of water on Mars, but some new research challenges that idea. And one of our most successful exoplanet finding tools has discovered another one, this time pretty close to home!
