The study of planets circling distant stars is scarcely more than a decade old — the fantastic assumption that planetary systems exist outside our own was first confirmed in 1991 — and already it is making exciting progress. Over 110 extrasolar planets have been detected so far. Now, a team of Canadian astronomers has found that one such planet actually is heating its parent star and leaving a telltale imprint of its travels. The finding bolsters astronomers' theoretical understanding of planetary formation and offers a new method of detecting elusive yet intriguing worlds that dance unseen in the sky.
