AUSTIN, Texas — When a team of researchers sifted through old data from the Hubble Space Telescope and discovered two hidden alien planets that had gone unnoticed for 13 years, they inadvertently found a new way to seek out alien worlds. Now, astronomers are expanding their search by applying the data-mining technique to 350 other stars that were observed in 1998 by a Hubble telescope instrument called the Near Infrared Camera and Multi-Object Spectrometer (NICMOS).
