In short: Nebulae appear as stunning celestial paintings, but their distinct hues reveal the underlying physics of gas and dust. This video explores what these colors actually signify about the life cycles of stars.

Nebulae are vast clouds of interstellar gas and dust that serve as cosmic nurseries or graveyards. Some represent the birthplaces of new stars, like the Orion Nebula, while others are the remnants of dead stars, categorized as planetary nebulae or supernova remnants.

The specific colors observed in these structures provide clues about their composition and environment. By understanding these visual cues, astronomers can distinguish between different types of nebulae and the various processes shaping our universe.
