First planet of extragalactic origin (artistâ€™s impression)
November 21, 2010
This artist's impression shows HIP 13044 b, an exoplanet orbiting a star that entered our galaxy, the Milky Way, from another galaxy. This planet of extragalactic origin was detected by a European team of astronomers using the MPG/ESO 2.2-meter telescope at ESO's La Silla Observatory in Chile. The Jupiter-like planet is particularly unusual, as it is orbiting a star nearing the end of its life and could be about to be engulfed by it, giving clues about the fate of our own planetary system in the distant future.
