For the first time scientists have observed a planet that originated outside our own galaxy.
Situated 2,000 light years from Earth this new planet was actually formed within a dwarf galaxy that merged with our own Milky Way galaxy several billion years ago.
To date about 500 planets have been discovered within our galaxy, but this is the first known to have been born elsewhere. The gas planet, at least 25 per cent heavier than Jupiter Ė or 400 times heavier than Earth Ė orbits a star that started life in a dwarf galaxy.
