The Hertzsprung-Russell Diagram,can now put all of these parameters together to form a picture of how a star evolves. This is often quite useful in many sciences to represent the characteristics, or data, about a group of objects in the form of a graph.

The Interstellar Medium and Protostars,m to be any sort of material that lies between one star and another. At the same time, we know intuitively that this cannot be true, for if space were empty, from what did stars form? This then leads us to the conclusion that perhaps space is not quite so empty, but filled with some sort of material

The Sun, Our Nearest Star, as sunspots, the sunspot cycle, etc. Instead, we will concentrate on the internal structure, means of energy production, and the manner in which energy is transported from its source to us on Earth. With this approach, it is possible to use the Sun as a benchmark with which to compare stars of diff

Binary Stars and Stellar Mass,culars or telescopes resolve themselves into two stars. Indeed, some apparently single stars turn out to be several stars! Many appear as double stars due to their lying in the same line of sight as seen from Earth, and these are called .. It may well be that the two stars are separated in space by
