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.'"

The Bad Astronomer writes "As much as 90% of previously hidden galaxies in the distant Universe have been found by astronomers using the Very Large Telescope in Chile. Previous surveys had looked for distant (10 billion light years away) galaxies by searching in a wavelength of ultraviolet light emitted by hydrogen atoms — distant young galaxies should be blasting out this light, but very few were detected. The problem is that the ultraviolet light never gets out of the galaxies, so we never see them. In this new study, astronomers searched a different wavelength emitted by hydrogen, and voila, ten times as many galaxies could be seen, meaning 90% of them had been missed before."

gregg writes "HM Cancri has been confirmed as a binary system of two white dwarfs orbiting each other so closely that they complete one orbit every 5.4 minutes; they are separated by a mere 8 Earth diameters. 'These are the burnt-out cinders of stars such as our Sun, and contain a highly condensed form of helium, carbon and oxygen. The two white dwarfs in HM Cancri are so close together that mass is flowing from one star to the other. HM Cancri was first noticed as an X-ray source in 1999, showing a 5.4 minutes periodicity, but for a long time it has remained unclear whether this period also indicated the actual orbital period of the system. It was so short that astronomers were reluctant to accept the possibility without solid proof. '"
