Between the orbits of Mars and Jupiter discovered "cemetery" of comets

Colombian province of astronomers from the University of Antioquia in Medellin, observing space objects found between the orbits of Mars and Jupiter cluster of comets, which over millions of years show no signs of activity.

However, as scientists believe, under certain conditions, "dormant" comets can "come alive".

According to researchers, the comet "went into hibernation" due to the small amount of energy they receive from the Sun, as well as a lack of water ice and frozen carbon dioxide, a gas necessary for the tail of a comet. In order to bring this state of the comet, enough energy increase by only 2%, helped by small changes in the orbit of their neighbors. True fly "revived" comets may be not much, and it happens very rarely.

Point of cosmic objects astronomers dubbed "Lazarus" after the biblical character Lazarus, risen on the fourth day after death.
