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.

Ep. 580: Exploding Dwarfs

Astronomy Cast Ep. 580: Exploding Dwarfs By Fraser Cain & Dr. Pamela Gay So you think that a white dwarf star is the end of a stellar life, and it's all downhill from there, a long, slow cool down towards the end of everything. But in some situations even dead stars can get exciting again, briefly becoming some of the brightest objects in the Universe. And maybe, just maybe, the last exciting thing that'll ever happen in the Universe.

Ep. 579: White and Black Dwarf Stars

Ep. 579: White and Black Dwarf Stars

Astronomy Cast 579: White and Black Dwarf Stars by Fraser Cain & Dr. Pamela Gay I've got some bad news for you. Stars die. At some point in the next few billion years or so our Sun is going to start heating up, using up all the fuel in its core, and then eventually die, becoming a white dwarf. It'll then slowly cool down to the background temperature of the Universe, becoming a black dwarf. Let's learn about this fascinating process.

Ep. 577: Mars in Opposition

Astronomy Cast 577: Mars in Opposition by Fraser Cain & Dr. Pamela Gay Every 2 years or so Mars lines up nicely with the Earth. It takes only 2 minutes to communicate with the rovers. You can see the polar ice caps in a small telescope. And it's the best time to send your spacecraft to the Red Planet.  Oct 3rd: Moon & Mars conjunction, 1.1° separation. Oct 6th: Mars opposition. Dec 21st: Jupiter/Saturn conjunction, 0.1° separation! Feb 18th "Percy" lands on Mars' Jezero crater.

Ep. 575: Observing The Moon

Astronomy Cast Ep. 575: Observing The Moon by Fraser Cain & Dr. Pamela Gay As amateur astronomers, we curse the Moon every month. Seriously! Why doesn't someone get rid of that thing! This week, something occurred to us. What if we actually pointed our telescopes at the Moon? What would we see? The Lunar "X" that Fraser talked about will be visible this Friday, June 26th! So go out with binoculars or a telescope and enjoy!
