Life Zone - an area around the star, which, speaking in general terms, the conditions are favorable for the existence of liquid water and life-threatening. Meanwhile, Venus zone - is quite another. This is - fierce hell forge worlds.

Hell solar system planet Venus, perhaps an indication of how close to the star can be the world reveals new study. In this study, the authors brought a new concept - Venus zone around the star. They believe that this area will help to more accurately assess other areas surrounding the star.

"We believe that the Earth and Venus atmosphere began to form identical - said study lead San Francisco University astronomer Stephen Kane. - However, at some point in the development process atmospheres something has changed. Perhaps the most obvious difference in this case is the distance of the planets from the Sun. "

Life zone around a star is understood rather vaguely, as scientists of the necessary conditions for life does not know everything. Accepted that the temperature in this zone must be such that the water is in the liquid state. True, it is a large part depends on the planet's climate. Clouds, surface morphology and composition of the atmosphere are just a few of the eligibility factors for life.

In order to accurately know the distance from the star-based type of planet Venus, S. Kane, a group of researchers analyzed the exoplanet sought the space telescope Kepler, collected data and analyzed the solar stream (called. - Solar flux), vol. y., how much solar energy received by the planet.

Venus zone established between the two regions, the threshold at which the planet rotates too prevalent atmospheric greenhouse effect, and the threshold at which the planet is so close to the star, the energy of Sun blows the atmosphere into space. Between these two limits and lies of Venus area.

"If in the future we will see exoplanets by observing the planets Venus fragile dominated by greenhouse gas effect, shows that the distance between the planet and the star is one of the key factors - taught by S. Kane. - This will help to better understand the development of Venus and Earth history. "
