Cometary science is the study of comets, which are icy celestial bodies that originate from the outer regions of the solar system. These objects are composed of dust, rock, and frozen gases, and when they approach the Sun, they develop glowing comas and tails due to the sublimation of their ices. Understanding comets helps scientists learn about the early solar system and the building blocks of planets. Researchers in cometary science analyze the composition, structure, and behavior of comets using telescopes and spacecraft. Notable missions, such as Rosetta, have provided valuable data about comets like 67P/Churyumov-Gerasimenko. This research contributes to our knowledge of the origins of water and organic materials on Earth.
