A nebula is a vast cloud of gas and dust in outer space. These cosmic clouds are often the birthplaces of stars and planetary systems.
Nebulas can vary in size, shape, and composition, and they are illuminated by nearby stars or other forms of energy, creating stunning and colorful displays.
Some famous examples of nebulae include the Orion Nebula and the Eagle Nebula.
Nebulas play a crucial role in the formation and evolution of galaxies, as they contain the raw materials from which new stars and solar systems can emerge through gravitational collapse and fusion processes.
