An anonymous reader writes "Peter Jalowiczor is a gas worker from South Yorkshire, England. He's also the discoverer of four giant exoplanets, according to the University of California's Lick-Carnegie Planet Search Team. But he's not an astronomer and he doesn't even have a telescope. '...in 2005, astronomers at the university released millions of space measurements collected over several decades and asked enthusiasts to make of them what they would. ... From March 2007 Peter, 45, spent entire nights reading the data, working the figures, creating graphs. ... He then sent discrepancies he discovered back to the scientists in California where they were further analyzed to see if the quirks were caused by the existence of an exoplanet.'"
