EXOPLANET HISTORY
From pulsar timing to atmosphere spectra, trace the instruments and ideas that turned distant worlds into a field we can measure.
Why two “firsts”? The 1992 planets were the first confirmed exoplanets, orbiting the pulsar PSR B1257+12. In 1995, 51 Pegasi b became the first confirmed planet around a Sun-like main-sequence star.
Discovery milestone
The first confirmed planet around a Sun-like star made radial velocity a defining method.
