On top of that, without knowing the mix of ices on a comet’s surface, predictions of what material will be released and at what points are vague. A comet with a lot of dry ice will become active ...

And as it gets closer to the heat of the Sun, the ice heats up past the point of remaining solid — but rather than melting into water, it becomes a gas which erupts from the comet's surface in ...

their nongravitational accelerations imply that they're losing ices from their surface, which is an important characteristic of comets, says Taylor. How important were dark comets in delivering ...
