Update: 2024-06-18
Description
Astronomers have discovered thousands of exoplanets, revealing entirely new types of worlds that we don’t have in the Solar System. It is enough to start getting a rough sense of what kinds of planets are out there. What’s the big picture?

Show Notes
- Our World in Data has exoplanet data!
- Radial Velocity method is the OG way to find exoplanets
- Transits are now primary way to find planets
- Gravitational lensing also works to find planets
- Kepler and TESS are the current planet-finding awesomeness, but Roman is on the horizon
- Looks like most stars above a certain metallicity (10% the metallicity of the Sun or more) have planets!
- We are now measuring atmospheres of planets, but it’s early days… Need a 2nd JWST, please!
