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-metre telescope at ESO’s La Silla Observatory in Chile. European astronomers say they have discovered the first planet that comes from a galaxy outside the Milky Way, according to research released November 18, 2010 in the United States. The exoplanet is slightly larger than the size of Jupiter, the gaseous planet that is the largest in our solar system, and is orbiting a star 2,000 light years from Earth that has found its way into the Milky Way. The pair are believed to be part of the Helmi stream, a group of stars that remains after its mini-galaxy was devoured by the Milky Way some six to nine billion years ago, said the study in Science Express.
