Hotnews24h: One star over, a planet that might be another earth.
Another Earth could be circling the star right next door to us.
Astronomers announced on Wednesday that they had detected a planet orbiting Proxima Centauri, the closest neighbor to our solar system. Intriguingly, the planet is in the star’s “Goldilocks zone,” where it may be neither too hot nor too cold. That means liquid water could exist at the surface, raising the possibility for life.
