A Neptune-size planet orbiting a blue A-type star.

Artist’s concept of a Neptune-sized planet, left, around a blue, A-type star. UC Berkeley astronomers have discovered a hard-to-find gas giant around one of these bright, but short-lived, stars, right at the edge of the hot Neptune desert where the star’s strong radiation likely strips any giant planet of its gas.
