This gallery contains 74 images of different star systems with cometary belts (known as 鈥渆xocomets鈥�) taken with the Submillimeter Array (SMA) and the Atacama Large Millimeter/submillimeter (ALMA) radio telescope facilities. The stars in this study range in ages from very young to middle-aged like our Sun. This new study shows how comets play a role in the formation of stars and planetary systems.
