Earth could be unique among 700 quintillion planets in the Universe, study finds

Our main goal behind exploring the outer space, from the beginning is to search for some distant planets that harbor life. According to a recent research by an international team of astronomers put forward that there are less chances of life on other planets like Earth or Earth looks to be unique. They took all the data we have about the remote exoplanets and fed in to a computer model. Their evaluations create a “cosmic inventory” of terrestrial planets.

One of the researchers, Andrew Benson from the Carnegie Observatories in California, said “It’s kind of mind-boggling that we’re actually at a point where we can begin to do this." Benson said "It’s obvious that there are a lot of uncertainties in the calculation like this, our knowledge of all of these pieces is imperfect."

According to their calculations, our Earth resulted from some anomaly and don’t seem to be like the other planets that are older and larger but don’t harbor life.

Until now we only know about 2000 exoplanets outof 700 quintillion or so. We don’t have any evidence that whether these planets can sustain life or not. The researchers describe Earth’s formation as an implausible event of chance.

The team says that we would have to admit that we ended up here because of an improbable lottery draw, but maybe there is more to the lottery than we have comprehended earlier.

One of the team member, Erik Zackrisson from Uppsala University said "Whenever you find something that sticks out, that means that either we are the result of a very implausible lottery draw or we don’t understand how the lottery works."
