Breaking News : First Planet From Another Galaxy 'Discovered'
[Image: in_16.jpg]

Astronomers have discovered what they claim is the first planet from another galaxy.

A team at Germany's Max Planck Institute for Astronomy has found the planet, called HIP 13044 b, around a star which seems to be an interloper from another galaxy - by the way its gravity caused its host star to wobble.

Curiously, the star also contains fewer heavy elements - thought to be needed to build planets - than any other planet-hosting star yet discovered, the 'New Scientist' reported.

The planet, which is 1.25 times as massive as Jupiter, lies 2300 light years from Earth and orbits a bloated, ageing star slightly less massive than the sun.

The host star, called HIP 13044, is a member of a group of stars called the Helmi stream that have unusual, elongated orbits that bring them far above and below the disc of the galaxy where sun and most other Milky Way stars reside.

The Helmi stars are thought to be remnants of a small galaxy torn apart by the Milky Way some 6 billion to 9 billion years ago.

"This cosmic merger has brought an extragalactic planet within our reach,"said team member Rainer Klement.
