Stellar objects refer to celestial bodies within a galaxy that are primarily composed of gas, plasma, and other materials. These objects include stars, planets, moons, galaxies, and other celestial bodies that emit light or energy. Studying stellar objects provides valuable insight into the formation, evolution, and dynamics of the universe. Researchers in this area may investigate the lifecycle of stars, the formation of planetary systems, the behavior of black holes, and the structure of galaxies, among other topics. Their research often involves observing these objects through telescopes, analyzing data from space missions, and developing theoretical models to explain their properties and behavior.
