Astronomy Cast Ep. 726: Looking Back Over The Summer By Fraser Cain & Dr. Pamela Gay Streamed live Sep 9, 2024. We made all sorts of predictions, and some of the stuff we didn't know about last July, somehow, we still don't know about as we set up this episode on September 3! Join us for the first episode of Season 18 as we review all the crazy space science that happened during our Summer Hiatus. 

Astronomy Cast Ep. 173: Herschel Space Observatory - REMASTER By Fraser Cain & Dr. Pamela Gay From January 18, 2009. Last week we talked about Herschel the people – William Herschel, his sister Caroline, and his son John. This week we look at the Herschel Space Observatory, a mission launched in 2009 to reveal the coldest and dustiest regions in the Universe.

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.
