First extragalactic planet identified

By: Andrew Krammer

A Jupiter-like planet has been found orbiting a dying star on the edge of our own Milky Way galaxy, Universe Today reported.

The planet is orbiting a star 2,000 light years from Earth; both are believed to be part of the Helmi stream, which is a group of stars that remains after its mini-galaxy was devoured by the Milky Way, Yahoo reported.

The planet is slightly larger than Jupiter and its home galaxy is believed to have been devoured some six to nine billion years ago, scientists said.

"Because of the great distances involved, there are no confirmed detections of planets in other galaxies. But this cosmic merger has brought an extragalactic planet within our reach," Rainer Klement, of the Max Planck Institute of Astronomy, said.
