In 1992, scientists discovered the first planets orbiting a star other than our Sun. The pulsar PSR B1257+12 was discovered to have its own planetary system, and since then, exoplanet discoveries have exploded!
But did you know that long before that, back in the 1940s, 1950s and 1960s, a scientist studying Barnard’s Star — the second-closest star system to the Sun — claimed to have discovered the first exoplanets in history? This was no crackpot, either, but a pioneer of astrometry and one of the most respected scientists in his field, and one of the most exciting moments in (now forgotten) science history!
