The way in which we detect them is so incredible: either by noticing the periodic slight decrease in light as the exoplanet orbits its star, or by noticing the periodic slight wobble of the star around it and its expolanet's joint center of mass. When you think of what a tiny difference we're measuring, of something so dim and so far away, and the fact that we're able to actually resolve those things––it's just staggering.
