How Do Astronomers Find Exoplanets? Wiggles!

In space. So it's a spinning platform with two telescopes. And what the telescope is doing is it's measuring the exact time at which a star crosses through the field of view of each telescope. So every time it rotates and sees a certain star, it clocks that moment.

And if you have billions of such measurements, then you can calculate the exact positions of all of those stars with the utmost precision.

So the team that operates the Gaia telescope prepared a list of about 75 stars that appeared to be wiggling back and forth. And so our idea was, okay, these appear to be new planets from the astrometric method. Let's use the Doppler method to see if we can confirm them.

And as it turns out... Most of those 75 objects are not exoplanets. They are something else. Yeah. So the one that we found came from a long kind of sifting through of these candidates, ruling out most of them and arriving at so far just one that we're pretty sure is an exoplanet.

Sure. It is an unusually massive planet. It's almost 12 times the mass of Jupiter. Oh, wow. Wow. You might call it a super Jupiter.

It's orbiting around its star every 571 days. What? It's lower in mass and redder and less luminous than the sun.

It's pretty close by galactic standards.
