NGC2997 CHI-1 7h10 Bundle
The beautiful NGC 2997 is an almost face-on unbarred spiral galaxy located about 55 million light-years away in the southern constellation of Antlia.
This is a grand-design galaxy with a symmetrical, two-armed form. The arms host a series of dusty knots that are star-forming regions being generated through gas compression from density wave. At the core, the arms converge to form a circumnuclear ring with symmetrically-placed hot spots containing super star clusters.
Many HII regions can be seen in the arms as well as several far galaxies in the background and through the arms of NGC2997.
