It wasn't all that long ago that humans didn't even know for sure if planets existed outside of our solar system. We can see stars, of course, but spotting planets orbiting those stars? Well, that was impossible for a very long time. It's only in recent decades that technology has reached a point that allows us to spot signs of exoplanets far from our system, and NASA's TESS (Transiting Exoplanet Survey Satellite) has proven to be ridiculously good at spotting those planets.
In fact, the satellite has collected evidence of so many exoplanets that there is no way astronomers will ever be able to study them all. In a recent bulletin by NASA the space agency reveals that TESS has already spotted over 2,200 exoplanets in space. The plants range from huge to tiny, and some of them are likely rocky worlds much like our own planet. What's especially cool about this is the fact that TESS hasn't actually spotted any planets directly, but rather inferred their existence based on other evidence.
