Polysaccharides are a form of macromolecule that are found in humans, plants, animals and fungi. They are long stands of carbohydrate molecules (glucose) that are bonded together by glycosidic bonds. Polysaccharides usually contain a repeating pattern of the same carbohydrate molecules, and can be both branched and unbranched. Branched polysaccharides are known as amylopectin and consist of thousand of molecules bonded together with many branches. Unbranched polysaccharides are known as amylase and are one long strand of hundreds of molecules.

It was named by Pierre Gassendi in 1621, after the Roman goddess of dawn and the Greek name for wind. This phenomenon also occurs in the Southern hemisphere, where it is known as the “southern lights” or aurora australis. It is usually only observed near the polar regions, but has been seen outside these regions during high levels of solar wind. Some of the best places to view the northern lights include; Alaska, Canada, Norway and Siberia. The cause of the northern lights has been debated throughout history, but today science can answer the question.
