In 1996, comets were found to emit X-rays. These X-rays surprised researchers, because X-rays are typically emitted by hot objects and comets are cold. The X-rays were generated by the interaction between comets and the solar wind: when highly charged ions fly through a cometary atmosphere, they collide with cometary atoms and molecules. In these collisions, the ions will capture one or more electrons leading to emission of X-rays and far ultraviolet photons.

Les techniques d'observation des atmosphères cométaires sont nombreuses. Les plus anciennes sont l'imagerie et la photométrie (mesure de l'intensité d'une source lumineuse) dans le spectre visible; elles permettent de suivre l'évolution de l'activité cométaire et d'étudier la distribution des poussières.
