Morphology

milky + way + galaxy

The name is directly compositional: 'milky' describes the pale, milk-like appearance, 'way' conveys a band or path across the sky, and 'galaxy' denotes a star system, so together they denote a galaxy that appears as a milky band. This naming logic is cross-linguistically common (e.g., Spanish 'Vía Láctea'), so a B1 learner who knows the constituent words can readily infer the meaning.

Etymology

Milky Way Galaxy may come from the old image of a faint white band of stars across the night sky that looked like a river of milk. People long ago called that bright stripe the 'milky way', and that picture is why the whole galaxy has this name today.
