Hidden planet found in old Hubble data

A new technique has uncovered an extrasolar planet hidden in Hubble Space Telescope images taken 11 years ago.The new strategy may allow researchers to uncover other distant alien worlds potentially lurking in over a decade's worth of Hubble archival data. The method was used to find an exoplanet that went undetected in Hubble images taken in 1998 with its Near Infrared Camera and Multi-Object Spectrometer."
