Abstract

Worlds away from the Earth, 44 light years away in the Andromeda constellation, three Jupiter-sized planets are orbiting Upsilon Andromedae,a bright star 1.2 times the mass of our Sun and two-thirds of its 4.5 billion year age. This dramatic discovery, jointly announced by scientists from four research institutions on April 15, is the first planetary system ever found around a normal star, aside from our Solar System.

The finding suggests that planetary systems may be abundant in the Milky Way galaxy, and may indicate a new era of extrasolar planetary exploration and study, according to some scientists involved in the discovery.
