Did you know stars are born from collapsing dense clouds of dust and gas found in spiral galaxies. Also the life cycle of a star is determined by its mass.
Massive stars are classified by having a solar mass that is eight times the size of the sun during its main sequence life cycle stage. Not only do stars go through a life cycle, but they are also compared to the sun at the center of our solar system. On a clear night sky, massive ...
The Physical Features of Stars Before learning about the life cycle of stars and the astrophysical processes that are involved, it is useful to know something about the fundamental features of all stars in the universe. Stars are luminous spheres of burning gas that are between 13 and 180,000...
