A team of Astronomers from the University of Antioquia, Medellin, Colombia, have discovered a graveyard of comets. The researchers, led by Antioquia astronomer Prof. Ignacio Ferrin, describe how some of these objects, inactive for millions of years, have returned to life leading them to name the group the 'Lazarus comets'.

In this programme we examine the main asteroid belt between the orbits of Mars & Jupiter, the discovery of the minor planets, Lazarus comets, and the NASA DAWN space mission to image & study the asteroids Vesta and Ceres. We examine the latest results.

The next programme of Astronomy & Space will be available here from December 31st.
