Description
NGC 2403 is a nearby intermediate spiral galaxy in the constellation Camelopardalis, lying roughly 8 million light-years away on the outskirts of the M81 Group. Often compared to a smaller, more irregular cousin of M33, it features loosely wound spiral arms rich in young stars, dark dust lanes, and subtle star-forming regions scattered throughout its disk. With relatively little foreground clutter, the galaxy stands out cleanly against the surrounding star field, making its structure easy to study and appreciate.
This image highlights the galaxy’s layered spiral structure and textured disk, revealing fine detail in the arms and a softly concentrated central region without overwhelming brightness. The blue tones tracing the arms reflect regions of recent star formation, while warmer hues toward the core mark an older stellar population. Rather than emphasizing emission, the presentation focuses on NGC 2403 as a broadband stellar system, showing the galaxy as it naturally appears — a quiet, well-defined spiral suspended in deep space.
