Astronomy Science ~ If the planet wants to have water on its surface, (something that is necessary to support life as we know), then he must be within a certain distance from its star. Too close to the sun, the water evaporates. Too much, the water freezes. But according to new research shows that the majority of stars in our galaxy are in the habitable zone, where the temperature is precise enough to allow water to remain liquid at the surface and life can thrive.


The new calculations in a study published in the Monthly Notices of the Royal Astronomical Society shows that billions of stars of the Milky Way has 1 to 3 planets in the habitable zone, which means the planet is likely to have liquid water on its surface.

This calculation was made by a group of researchers from the Australian National University and the Niels Bohr Institute at the University of Copenhagen, is based on a method called Titius-Bode law. The law was created around 1770, predicts the distance of the planets in the solar system.

The researchers applied the law in 1000 exoplanets (and 3,000 candidate exoplanets) were discovered by the Kepler spacecraft. They studied 151 planetary system - where Kepler has detected between three to six planets - and found that the Titius-Bode law fits with the distance between the planets in the 124 system.

"Using the law of TB, we try to predict the location of more distant planets in the planetary system. But we just made a calculation for planets discovered Kepler," said Steffen Kjær Jacobsen, PhD student in the research group Astrophysics and Planetary Science at the Niels Bohr Institute in University of Copenhagen, said in a statement. After the planets were added, 151 planetary system shows 1-3 planets are in the habitable zone of their. The researchers believe this shows that most systems have planets orbiting at a distance appropriate to hold liquid water on the surface.

To help confirm their theory, they have marked a number of planets located in the habitable zone that would otherwise be seen Kepler at some point. They hope that other scientists will also see them. Unfortunately, being in the habitable zone does not mean that liquid water is present - and the presence of liquid water does not mean that life ever, could, would, or indeed exist. . But we always hope.
