New Zealand scientists have helped discover an Earth-sized planet in an Earth-like orbit more than 3000 light years away.
Astronomers from Auckland, Massey and Canterbury universities along with amateur astronomers were part of an international team that discovered the planet.
It is the first such planet found in a system that is home to two stars.
Though twice the mass of Earth, it doesn't support life, as it has temperatures of minus two hundred degrees.
But a physics lecturer at Auckland University, Nicholas Rattenbury, said the discovery shows there could be many more planets in the galaxy capable of supporting life.
Scientists used a technique known as microlensing to detect the planet.
Microlensing discovers planets by measuring how the gravity of a planet and its host star deflects light coming from background stars.
