In early 1992, while working for NRAO, he and the Polish astronomer Aleksander Wolszczan announced the discovery of two planets and a possible third around the pulsar PSR B1257 + 12 . Their discovery was confirmed in mid-1992. The discovery is remarkable because it was not only the first pulsar planets , but also the first ever exoplanets .
