NGC 5291 is a system of interacting galaxies in the constellation Centaurus. It is surrounded by a collisional ring, containing a young and star-forming tidal dwarf galaxy, [2] where dark matter has been detected.

2015年11月21日 · Explanation: Following an ancient galaxy-galaxy collision 200 million light-years from Earth, debris from a gas-rich galaxy, NGC 5291, was flung far into intergalactic space. NGC 5291 and the likely interloper, also known as the "Seashell" galaxy, are captured near the center of this spectacular scene.

2023年4月14日 · NGC 5291, an early-type galaxy surrounded by a giant HI ring, is believed to be formed from collision with another galaxy. Several star forming complexes and tidal dwarf galaxies are distributed along the collisional ring which are sites of star formation in environments where extreme dynamical effects are involved.

2013年9月6日 · This system, located in the western outskirts of the cluster Abell 3574, contains the lenticular galaxy NGC 5291 which is in close proximity to a disturbed companion and is flanked by an extensive complex of numerous knots extending roughly 4 min north and 4 min south of the galaxy.

2020年12月17日 · The elliptical galaxy NGC 5291 — the hazy oval cloud at the center of this image — was struck by a careening rogue galaxy over 300 million years ago. The aftermath of this cataclysmic collision is a ring of galactic debris — visible as the tenuous luminous clouds spreading left and right from the golden oval of NGC 5291.

NGC 5291 and the likely interloper, also known as the "Seashell" galaxy, are captured near the center of this spectacular scene. The sharp, ground-based telescopic image looks toward the galaxy cluster Abell 3574 in the southern constellation Centaurus.
