NGC 7458 is a bright and well-defined elliptical galaxy located in the constellation Cetus. Elliptical galaxies are characterized by a strong concentration of light toward their centers that fades rapidly outward, and they lack the distinct structures seen in spiral galaxies. The overall reddish color of NGC 7458 indicates that it is composed predominantly of old stars. Elliptical galaxies in the present-day Universe are known to contain many very old stars, often more than 10 billion years old.
