‘Alien’ Planet Discovered Circling Dying Star
Astronomers claim to have discovered the first planet originating from outside our galaxy.
The Jupiter-like planet, they say, is part of a solar system which once belonged to a dwarf galaxy.
This dwarf galaxy was in turn devoured by our own galaxy, the Milky Way, according to a team writing in the academic journal Science.
The star, called HIP 13044, is nearing the end of its life and is 2000 light years from Earth.
The discovery was made using a telescope in Chile.
The planet is quite close to the star it is orbiting, and survived a phase in which its host star went through a massive growth after it depleted its core hydrogen fuel supply, a phase known as the “red giant” stage of stellar evolution.
