Star-forming regions are areas in space where new stars are born. These regions are often found in giant clouds of gas and dust, known as molecular clouds. The dense parts of these clouds collapse under their own gravity, leading to the formation of stars. These regions are typically located in galaxies, including our own Milky Way. They can be identified by their bright emissions in certain wavelengths of light, such as infrared, which helps astronomers study the processes involved in star formation. Understanding these regions is crucial for learning about the lifecycle of stars and the evolution of galaxies.
