Cometary studies focus on the investigation of comets, which are icy celestial bodies that release gas and dust, forming a glowing coma and tail when they approach the Sun. These studies help scientists understand the composition, structure, and behavior of comets, providing insights into the early solar system. Researchers use various methods, including telescopic observations and spacecraft missions like Rosetta and Deep Impact, to gather data on comets. This information can reveal the chemical makeup of comets, their orbits, and their potential impact on Earth, contributing to our knowledge of planetary formation and the origins of water and organic materials on our planet.
