Daily Mail: An amateur astronomer in the UK has discovered four new planets—without using a telescope. Peter Jalowiczor, a gas worker from Rotherham, South Yorkshire, discovered planets HD31253b, HD218566b, HD177830c, and HD99492 by using two home computers to analyze images released by the University of California, Santa Cruz, as part of the Lick–Carnegie Exoplanet Survey. Jalowiczor, a member of South Yorkshire’s Mexborough and Swinton Astronomical Society, said, “It is an honor and privilege to be listed in the [ Astrophysical] Journal and I hope that my work will inspire others.”
The finding that the Saturnian moon may host layers of icy slush instead of a global ocean could change how planetary scientists think about other icy moons as well.
