The latest inter-stellar imagery showcases a number of Earth sized planets throughout the galaxy. Recently scientists have discovered an Earth-like exo-planet named “Proxima b” orbiting the star “Proxima Centauri” in one of our nearest neighboring solar systems. Proxima b is in the “Goldilocks zone,” similar to Earth’s relative distance from the Sun, which facilitates moderate temperature. This raises the possibility that liquid water could exist on Proxima b’s surface, and water raises the potential for finding life in that planet.
Can we find any trace of extraterrestrial life? And, if we do happen to discover another civilization, can we communicate with them? Every year, millions of small meteorites fall onto the Earth. Might there were some tiny alien life hitching a ride aboard the meteorite?But Earth isn't the only planet in the Solar System.
