Comets as a research area encompass the multidisciplinary study of small icy bodies in the Solar System, focusing on their composition, physical properties, dynamics, and role in planetary system formation and evolution. This field integrates observational astronomy, spectroscopy, celestial mechanics, laboratory astrophysics, and space mission data to characterize volatile and refractory components, dust-gas interactions, nucleus structure, coma and tail formation, and outgassing processes. Research addresses orbital evolution, non-gravitational forces, and reservoirs such as the Kuiper Belt and Oort Cloud, with implications for understanding primordial Solar System materials, delivery of volatiles and organics to terrestrial planets, and comparative planetology.
NASA unveiled close-up pictures on Wednesday of the interstellar comet that's making a quick one-and-done tour of the solar system.

An interstellar comet that originated outside our solar system has just made its closest pass to the sun, brightening dramatically and rapidly as it did so. The reason for the sudden extreme activity is currently puzzling ...
A research team led by the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has used the Tianma Radio Telescope to conduct multi-band radio observations of the returning comet 12P/Pons-Brooks (12P). They ...
