Take a fact-based journey through the cosmos. Tune in to hear weekly discussions on astronomical topics ranging from planets to cosmology. Hosted by Fraser Cain (Universe Today) and Dr. Pamela L. Gay (Planetary Science Institute), this show brings the questions of an avid astronomy lover direct to an astronomer. Together Fraser and Pamela explore what is known and being discovered about the universe around us. Astronomy Cast is supported thru patreon.com/AstronomyCast.
Astronomy Cast Ep. 643: Sagittarius A*
Astronomy Cast Ep. 643: Sagittarius A* by Fraser Cain & Dr. Pamela Gay All the waiting is over, we've finally seen the image of the event horizon from the supermassive black hole at the heart of the Milky Way. Different shaped blobs! And a black circle in the middle. What are we looking at? Today we're going to explain the picture, and what's next for the Event Horizon Telescope.
Astronomy Cast Ep. 642: Is the Sun... Normal?
Astronomy Cast Ep. 642: Is the Sun... Normal? by Fraser Cain & Dr. Pamela Gay We've always assumed that we lived in a perfectly normal star system with a normal star and normal planets. It's all... normal. But with our modern understanding of billions of stars, just how normal is our Sun, anyway?
Astronomy Cast Ep. 641: Can Planets Be Alive?
Astronomy Cast Ep. 641: Can Planets Be Alive? by Fraser Cain & Dr. Pamela Gay The Earth is teeming with life, but the upper atmosphere to kilometers underground. There's no question that our planet has life. But is our planet itself alive? This is a question posed back in the 1970s as the Gaia hypothesis, and it got its share of criticism. Some new ideas have been proposed to bring this hypothesis to the modern era as we search for exoplanets.
Astronomy Cast Ep. 640: Survey Science: Newest Projects & Results
Astronomy Cast Ep. 640: Survey Science: Newest Projects & Results by Fraser Cain & Dr. Pamela Gay There are general-purpose telescopes and missions that astronomers can use to study specific objects. And there are the survey missions that look at the entire sky, which astronomers can use to answer questions about the Universe. We've talked about surveys in the past, but the landscape is changing quickly so it's time for an update.
Astronomy Cast Ep. 639: Big Qs Update: Dark Matter, Dark Energy, Etc.
Astronomy Cast Ep. 639: Big Qs Update: Dark Matter, Dark Energy, Etc. by Fraser Cain & Dr. Pamela Gay Knowledge moves forward, and so, we must move with it. Today we'll give you an update on some of the most fascinating, fast-changing topics in astronomy, astrophysics and cosmology.
Astronomy Cast Ep. 638: Simulating Space Missions
Astronomy Cast Ep. 638: Simulating Space Missions by Fraser Cain & Dr. Pamela Gay Although humans have never actually been to Mars, explorers have simulated many aspects of Mars missions here on Earth. There are missions under the ocean, on the tops of volcanoes, in the harsh Canadian north, and even in bed that simulate the limitations of spaceflight, and teach us many of the lessons to prepare us for the real thing
Terrific conversations on the stars, space, the physics of the universe, and the science and engineering of how humanity gains its knowledge.
A new drinking game. Every time Fraser says “right,” you get to take a shot. You will be trashed by the end of the show.
Phenomenal podcast! Informative and entertaining. Treat yourself and give them a listen.
