NASA | How to Cook a Comet

The video tutorial explains how to prepare a comet for a solar approach, focusing on sublimation, tail formation, and the effects of solar radiation. It covers the process of sublimation, where the comet's surface material transitions from solid to gas, forming a tail. The tutorial also discusses how ultraviolet light affects the comet's brightness and the dynamics of vapor jets causing rotation. As the comet nears the sun, its tail disappears, and the sun's gravity deforms it. Observing sublimation provides insights into the comet's composition, density, and mass, with the hope that the comet remains intact for future visits.
