How do astronomers find exoplanets? Space EarthSky

The astronomers studied light from 51 Pegasi b the first exoplanet discovered orbiting a mainsequence star (a Sunlike star), using the High Accuracy Radial velocity Planet Searcher (HARPS) instrument at the European Southern Observatory's La Silla Observatory in Chile.

Finding exoplanets means measuring the light from a star and looking for the telltale dip in the star's light that happens when a planet crosses in front of the star. Find the dip once and you may be onto something, find it twice and you now know how long the planet takes to orbit the star.

Amateur astronomers have previously detected the presence of exoplanets, but only after professionals made the initial findings. The newly discovered planet is just the second one found by gravitational microlensing, an effect predicted by Einstein's general theory of relativity.
