Which type of galaxy is described as broad, unordered, and lacking new star formation?

An elliptical galaxy is characterized by its smooth, rounded shape and a lack of distinct structure, which gives it a broad and unordered appearance. Unlike spiral galaxies, which have well-defined arms and regions with active star formation, elliptical galaxies generally contain older stars and exhibit very little gas and dust, resulting in minimal new star formation. This absence of ongoing star formation contributes to their feature of being relatively uniform without the vibrant activity seen in other galaxy types.

Elliptical galaxies can encompass a wide range of sizes, from small dwarf ellipticals to massive giant ellipticals, but they all share these distinctive characteristics that set them apart from spiral and irregular galaxies.
