For the past 400 years, astronomers have sought to observe and interpret the Universe by
building more powerful telescopes. These incredible instruments extend the capabilities of …

The physical properties of cometary nuclei observed today relate to their complex history
and help to constrain their formation and evolution. In this article, we review some of the …
