In a new study scientist suggests most habitable planets in the universe are dominated by oceans and the extent could be more than 90 percent. Our Earth is covered with 70 percent of water.
Details of the finding are published in The Monthly Notices of the Royal Astronomical Society. It writes that most of the habitable planets could be extremely wet.
The researchers add Earth is unique in the cosmological scheme of things and it will be really hard to find a twin in the universe and this may be the reason we have never made contact with an extraterrestrial intelligence.
However, it is still a big question how the planets get their water. The present theory prevails that most of the water of our planet was delivered by asteroids and comets.
Astrophysicist Sean N. Raymond said he was little puzzled about the new study and there are plenty of unanswered as well as relevant questions.
Raymond was not included in the study. It is still a question from where the planets get water.
It is also being said the larger planets are more prone to flooding compared to the smaller ones.
