The endeavor, long considered a scientific backwater with little chance of success, is now one of the hottest fields in astronomy.
Like any nascent field of science, the search for exoplanets poses a challenge that has lured both established researchers and ambitious students. These pioneers aim to detect planets too distant to see directly, by discerning the subtle wobbles of stars being tugged back and forth by the planets, as well as slight dimmings
