Ep. 574: Trojan Asteroids

We imagine the asteroid belt as the place where all the rocks hang out in the Solar System, but there are two huge bands of asteroids that orbit the Sun with Jupiter called the Trojans. And soon, we might actually get a chance to see them up close.

Ep. 573: Exoplanet Atmospheres

Ep. 573: Exoplanet Atmospheres

Not only have astronomers discovered thousands of exoplanets, but they’re even starting to study the atmospheres of worlds thousands of light-years away. What can we learn about these other worlds, and maybe even signs of life.

Ep. 572: Twists in Planet Formation

Ep. 572: Twists in Planet Formation

We’re all looking forward to the next generation of exoplanetary research, where we get to see pictures of planets directly. But astronomers are already making great strides in directly observing newly forming planets, helping us understand how our Solar System might have formed.

Ep. 571: Extreme Binaries

Ep. 571: Extreme Binaries
