👉 Astronomy "pimples" refer to the dramatic and often visually striking nebulae, or interstellar clouds of gas and dust, that appear as large, irregular patches of light and dark in the night sky. These structures are formed by various processes such as stellar winds, supernova explosions, and the collapse of molecular clouds, which can lead to the formation of new stars. The bright regions within these nebulae are often illuminated by young, hot stars, while the darker areas are dense with dust that blocks light. These cosmic formations provide astronomers with invaluable insights into star formation, the lifecycle of stars, and the chemical composition of galaxies.
