Stars are born and die within the Milky Way from "summary" of The Milky Way by Moiya McTier
Stars, those brilliant celestial bodies that light up the night sky, have a fascinating life cycle that is intimately connected to the Milky Way. Within the vast expanse of our galaxy, stars are both born and die in a spectacular display of cosmic evolution. The Milky Way, our home in the universe, serves as the stage for this celestial drama to unfold. The birth of a star begins with a dense cloud of gas and dust known as a nebula. Within these clouds, gravity pulls the material together, causing it to collapse and form a protostar. As the protostar continues to gather mass, its core becomes hot and dense enough for nuclear fusion to ignite, marking the official birth of a new star. These newborn stars shine brightly, illuminating the dark corners of the Milky Way with their radiant energy. However, the life of a star is not eternal. Eventually, a star will exhaust its nuclear fuel and reach the end of its life cycle. Depending on its mass, a star may undergo a s...
