Astronomers discover comets in asteroid belt that can revive after millions of years

Astronomers have discovered a ‘comet graveyard’ within the Solar system’s asteroid belt, consisting of ‘Lazarus comets’ that could jump back to life after having been inactive for millions of years. The ‘enormous graveyard of ancient dormant and extinct rocky comets’ was discovered in the asteroid belt between Mars and Jupiter, according to researchers from the University of Antioquia in Colombia. Meanwhile, comets are traditionally thought to come from two much further locations – the Kuiper Belt and the Oort Cloud, trans-Neptunian objects that lie at extreme distances from the Sun. In the last decade twelve active comets have been discovered in the asteroid main belt region, but scientists have managed to describe their origin for the first time. Read More at RT News.
