IN BRIEF Definition: Celestial objects with intense gravitational fields. Composition: Very compact, high mass/size ratio. Role: Impact on the growth of galaxies. Event horizon: Limit beyond which nothing can escape. Time travel: The gravity of a black hole allows for time dilation. Environment: Influence on galactic structures and their dynamics. Scientific research: Studies conducted to … Read more
IN SHORT Birth: Formation of a star from a nebula. Main sequence phase: Stabilization and fusion of hydrogen into helium. Red giant: Expansion as hydrogen depletes, the star becomes a red giant. Variable end: Depending on its mass, it can become a white dwarf or explode into a supernova. To die: Results in a supernova … Read more
IN BRIEF Star formation: Formation from the gravitational contraction of a nebula. Protostars: Clouds of gas that continue to contract to develop a star. Composition: Balls of gas mainly composed of hydrogen and helium. Process: Gravitational collapse of interstellar clouds. Stellar evolution: Life cycle encompassing the birth, evolution, and death of stars. Ongoing formation: About … Read more
