Deep-Sky Objects

Deep-sky objects are celestial objects that exist outside our solar system. Three major types of deep-sky objects are nebulae, star clusters, and galaxies.

A face-on spiral galaxy sits near the center of the frame, its bright, compact core surrounded by two broad, curving arms mottled with pale blue and pinkish patches. A smaller, hazier companion galaxy clings to the outer edge of one arm, slightly offset and to the side, where their halos appear to blend. The scene is set against a dark background sprinkled with faint foreground stars and a few tiny, distant galaxies.
