☢️ The First Planets Ever Found Outside Our Solar System Were Orbiting...

On January 9, 1992, astronomers Aleksander Wolszczan and Dale Frail published confirmation of the first extrasolar planets ever detected in the journal Nature (Vol. 355, pp. 145–147). The planets — designated PSR 1257+12 B and PSR 1257+12 C — were found orbiting PSR 1257+12, a millisecond pulsar located approximately 2,300 light-years from Earth in the constellation Virgo.

A pulsar is the collapsed remnant of a massive star that underwent a supernova — a rotating neutron star emitting focused beams of electromagnetic radiation. PSR 1257+12 rotates 161 times per second. The radiation environment on the surface of its orbiting planets is lethal by any known biological standard.

For all of recorded human history prior to January 9, 1992, the existence of planets beyond our solar system was unconfirmed. The first confirmed worlds we found were not candidates for life. They were irradiated remnants orbiting a dead star. A third planet in the system, PSR 1257+12 A, was confirmed in 1994.
