Five Earth-sized planets have been identified around a distant star in the Milky Way galaxy in a discovery that raises the possibility of eventually finding another rocky planet where water-based life may exist, scientists said.
Led by University of Birmingham, astero-seismologists have discovered a solar system with five Earth-sized planets dating back to the dawn of the Galaxy.British scientists have discovered five Earth-sized planets around a distant star in the Milky Way galaxy and also expecting of possibility of finding life out there.
Thanks to the Nasa Kepler mission, the scientists announced on Tuesday the observation of a Sun-like star (Kepler-444) hosting five planets with sizes between Mercury and Venus.
All five planets are too close to their sun and too hot to harbour life but the fact that they were formed many billions of years ago when the galaxy was still young suggests that rocky, Earth-sized planets could be more ubiquitous than previously thought.
“There are far-reaching implications for this discovery,” lead researcher Tiago Campante said in a statement. “We now know that Earth-sized planets have formed throughout most of the Universe’s 13.8 billion year history, which could provide scope for the existence of ancient life in the Galaxy.”
Since the newly discovered planets are older than Earth is, researchers hope that by studying them, they may learn more about planet formation — including what could be in store for our home.
