So you use this new method to measure how, like, stars wiggle, and it's called astrometry. Like, what is astrometry?

Oh, wow. Okay. Okay. So it's just straight up measuring where the star is.

Yeah, and that's what I thought we were actually measuring when I first learned about star wiggling, like back in the 1990s. But you're saying that that was actually the Doppler method, and we were measuring the speed of stars rather than observing those stars move.

Okay, okay. So using this new method, what kind of planets do we expect to see?

Okay, okay. So using this new method, what kind of planets do we expect to see?

So why is that?

So why is that?

So why is that?

Got it.

Got it.

Got it.

So why is this method possible now, like when it wasn't before?
