Nearly a year ago, an astronomer issued a serious challenge to the case for an extrasolar planet--the first to be discovered around a sunlike star. He presented evidence that slow jitters in the spectrum of the parent star, thought to result from a planet's periodic tug, were actually due to a pulsation of the star's gases. Now the astronomer and at least three other groups say they have been unable to reproduce his earlier results. What looked like a planet killer may have been just a chance alignment of noisy data points.
