Galaxy is loaded with Earth-like planets

Our galaxy is loaded with Earth-like planets each of which could be supporting Extra Terrestrial life, a leading astronomer said yesterday.

Experts speaking at a science conference in the US think we could even find the first one in the next FOUR years.

In recent years more than 300 new planets beyond our solar system have been found, and researchers think it is only a matter of time before a habitable world is discovered.

Dr Alan Boss from the Carnegie Institution for Science believes each Sun-like star has on average one Earth-like planet meaning are billions out there. 

With the potential for there to be millions of alien life-forms out there isn't it rude that they don't come and visit?
"We already know enough now to say that the Universe is probably loaded with terrestrial planets similar to the Earth," Dr Boss told the American Association for the Advancement of Science in Chicago.

"We should expect that there are going to be many planets which are habitable, so probably some are going to be inhabited as well.

"Within about three or four years, there will be a press conference at Nasa headquarters and they will tell us just how frequently Earth-like planets occur and once we know that we will know how to take the next steps in the search for habitable planets," he added.
