A major part of astrophysics research is building ever and ever more sensitive instruments, and coming up with clever new ways to extract signals from the noise while dealing with increasingly large datasets.

A case in point: the amazing detection of Gliese 832c, a "super-Earth" that's only 16 light years away. To make the detection, a team of researchers, headed by Robert Wittenmyer at UNSW in Australia, combined data from three different experiments with some statistical algorithms.

Gilese 832c is currently the closest planet of a comparable size to Earth, so this is a pretty exciting discovery.
