NASA Announces Discovery Of New Earth-Like Planet
July 27, 2015
Astronomers at NASA announced at a news conference on Thursday the discovery of a new planet described as "Earth's bigger, older cousin."
The planet, Kepler-452b, is 60% larger than Earth and is located in a region of the constellation Cygnus that may contain life-sustaining liquid water, CNN reported. It is about 1,400 light years away from Earth.
Kepler-452b orbits its star -- which is similar to our Sun -- every 385 days, and scientists estimate it's about 6 billion years old.
"That's substantial opportunity for life to arise, should all the necessary ingredients and conditions for life exist on this planet," said Kepler researcher Jon Jenkins, according to CNN.
Thursday's news conference fell on the 20-year anniversary of the discovery of the first planet with a sunlike star outside of our solar system, The New York Times reported.
