How do scientists use wavelengths to study composition of stars?

They use a special kind of device that reads the wavelengths shown in the stars, i think. The wavelengths react differently to certain chemicals, but based on these wavelengths, the scientists can tell which chemicals are present or absent in stars.

Why do scientists study comets?

The study of comets may seem to be removed and irrelevant to studies on Earth. However, comets are thought to have had a huge impact on the evolution of life as we know it. It has been suggested that they brought water and some organic molecules to Earth, allowing life to begin. The study of the composition of comets allows scientists to draw parallels between our solar system and distant stars, and so can tell us about our own planet's history and also about far off galaxies. This obviously can have major implications for our understanding of the universe and our place within it.
