Ep. 539: Weird Issues: Why We Don't Know the Age of Saturn's Rings
23/09/2019 Duración: 59minHow old are Saturn's rings? They could be brand new, or they could be as ancient as the Solar System itself. Planetary scientists thought they knew the answer thanks to new data from Cassini, but new ideas are calling even that into question.

Ep. 538: Asteroids: Rubble piles of the Solar System
16/09/2019 Duración: 37minThanks to all the work from Hayabusa 2 and OSIRIS-REx, astronomers are getting a much better look at the smaller asteroids in the Solar System. It turns out, they're piles of rubble... but fascinating piles of rubble. Let's talk about what we've learned so far.

Ep. 530: Astronomy of the Andes - Then and Now Pt. 2
12/05/2019 Duración: 31minSouth America, especially the Atacama Desert in Chile has become one of the best places in the world to put a telescope. It's dry, high, and the nights are clear. Today we'll talk about the monster telescopes already in operation in this region, and the big ones coming soon.

Ep. 528: Modern Astronomy of the American Southwest
29/04/2019 Duración: 43minLast week we talked about the ancient astronomy of the American Southwest. But this is actually Pamela's stomping grounds, and she's spent many a night perched atop mountains in this region staring in the night sky with gigantic telescopes. How does astronomy get done in this region today?

Ep. 524: Judging Age & Origins, part 3 - Beyond Our System
01/04/2019 Duración: 01h41sWe learned how to figure out the ages of objects in the Solar System, now we push out into the deeper Universe. What about stars, galaxies, and even the Universe itself? How old is it? This episode is part 3 of a series.
