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.
