Earth-like bouldered planets that bodies could alive on may be added accepted in the cosmos than stars, says an all-embracing aggregation of all-embracing scientists which included an Indian-origin researcher.

Aditya Chopra at Australian National University and colleagues affirmation that free whether these planets are accouter has become the new angelic beaker of astronomy.

"The new-found affluence of planets, accumulated with the abundant beyond ambit of inhabited earthbound environments suggests that accouter planets are common. This increases the anticipation of award some
affectionate of exoteric life," said Charley Lineweaver, who led the team.

Chopra said the best estimates of habitability appear from the planet we apperceive best -- Earth.

"By comparing the inhabited and arid regions of Earth, we can analyze the best important factors that actuate habitability. For earthbound life, those factors are aqueous water, a attenuated ambit of temperature, and an activity source," he said in a university release.

Dr Lineweaver added: "Habitability is not aloof a catechism of abiotic ecology altitude -- the attendance of activity may be appropriate to advance the habitability of a planet over billions of years.

"Planetary habitability is a circuitous and ambagious abstraction that we are alone alpha to get our active around, but as a breed that wants to survive, it is in our absorption to get our active about it soon."

The allegation accept been appear in the 'Annual Reviews of Earth and All-embracing Sciences' journal.
