Ep. 723: Exoplanets by the Numbers
Manage episode 424165274 series 5524
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!
