Of the first exoplanets found, most were detected by:
A) noting the drop in the star's light as the planet transits its disk. B) imaging them with the HST in the infrared, where they are easier to stop. C) noting the Doppler shifts of the star as the planet orbits it from side to side. D) receiving radio transmissions from them, much like Jupiter emits. E) detecting the oxygen in their atmospheres spectroscopically.
