Astronomy Cast Ep. 172: William Herschel - REMASTER By Fraser Cain & Dr. Pamela Gay From January 11, 2010. Ancient astronomers knew of 5 planets, Mercury, Venus, Mars, Jupiter and Saturn – 6 if you count Earth. And then in 1781, William Herschel discovered an entirely new planet, Uranus, boosting the number of planets to 7. Let’s learn about Herschel, his equipment, his discoveries, and his sister Caroline – an accomplished astronomer all on her own!

Astronomy Cast Ep. 88 - The Hubble Space Telescope - REMASTER By Fraser Cain & Dr. Pamela Gay From May 12, 2008. Our understanding of the cosmos has been revolutionized by the Hubble Space Telescope. The breathtaking familiar photos, like the Pillars of Creation, pale in comparison to the astounding amount of science data returned to Earth. Hubble’s getting old, though, serviced several times already, and due for another mission later this year. Let’s relive the historic observatory’s amazing life so far, and see what the future holds.

Astronomy Cast Ep. 162: Edwin Hubble - REMASTER By Fraser Cain & Dr. Pamela Gay From November 2, 2009. You might know the name “Hubble” because of the Hubble Space Telescope. But this phenomenal observatory was named after one of the most influential astronomers in modern history. Hubble discovered that galaxies are speeding away from us in all directions, leading to our current understanding of an expanding Universe. Let’s learn about the man behind the telescope.

Astronomy Cast Ep. 219 - Planck Mission - REMASTER By Fraser Cain & Dr. Pamela Gay From February 7, 2011. Another mission named after a famous physicist. This time we’re looking at the Planck mission, designed to study the Cosmic Microwave Background Radiation over the entire sky. Like the previous WMAP mission, this will help astronomers understand the first moments after the Big Bang.   This Episode is made possible thanks to our Patrons on Patreon.

Astronomy Cast - Ep. 218 REMASTER - Max Plank By Fraser Cain & Dr. Pamela Gay From Jan 31, 2011. It’s time for another action-packed double episode, where we meet a man and his mission. This time around its German physicist Max Planck, considered to be the father of quantum theory – he was later granted a Nobel Prize for just that discovery. Let’s take a trip back just over 100 years to learn about the man who changed our understanding of the very small.

Streamed live on Jun 24, 2024. Normally Pamela refuses to think about the future. But today, on our final episode before hiatus, she’s throwing out those rules. It’s like the PURGE! Here’s what we’re excited about for the future. Especially for the next couple of months until we return in September.   This Episode is made possible thanks to our Patrons on Patreon.

From Pamela: I also have a favor to ask - I'm working on a research project with my collaborator Sanlyn Buxener on what factors help and hinder people learning and doing science. Can you please take our survey?
