Astronomers announced habitability “of planets-the oceans”
Most of the “planet-oceans”, composed almost entirely of water, should remain habitable for a very long time.

Scientist Edwin Kite of the University of Chicago and a colleague have created a computer model of the water world whose properties can be varied in a very wide range of values. As a result, they concluded that “it is not necessary to have a complete “clone” of the Earth, with her oceans and continents, for the origin of life”.
“On average, about 10% of the worlds oceans will have the correct position in orbit and composition to ensure that their climate has remained stable for several billion years,” — says the article of the Astrophysical Journal.
Over the past few years orbiting telescopes have discovered more than a thousand exoplanets. Many of rocky planets are so-called “supertall” — their mass, size and density are approximately in the middle between the earth and the gas giants.
Planetary scientists suggest that they represent the “ocean” of the planet, most of the mass of which is water.
Astrophysicists from Canada previously reported that the radio telescope caught the signal that occurred, presumably, because of the blast outside the borders of our Solar system.
According to experts, the duration of the explosion was only a few milliseconds. However, the device still managed to capture a quick burst. According to astronomers, this could be a signal from a powerful source, if able to get close to the Ground.
