Take, for example, the newly discovered parent star HD38529 . Like most of the known extrasolar planets , HD38529's planet was discovered by detecting the telltale Doppler wobble in the parent star's spectrum. There is even evidence in the wobble data that HD38529, and other stars with one known planet have additional massive planets orbiting them. In this dramatic artist's vision, HD38529 and its newfound world are viewed from the moon of another massive ringed planet orbiting farther out. The ringed planet's moon is imagined to have a thin atmosphere and a surface covered with icy sheets and ridges similar to those found on Jupiter's moon Europa .
