peculiar galaxies

Galaxies that do not conveniently fit into the regular classification schemes of normal galaxies. These comparatively rare objects include active galaxies, starburst galaxies, Markarian galaxies, interacting galaxies, single irregular or disturbed galaxies, dwarf galaxies, ring galaxies, and spiral galaxies with peculiar spiral arms or even with one or three arms.

All the NGC companion galaxies are listed in the accompanying table, and you'll notice that the closely interacting galaxies NGC 5544 and NGC 5545 (also cataloged as peculiar galaxy Arp 199), are also included--be sure to have a look while you're in the neighborhood.
ISLAMABAD -- Scientists have just found that a peculiar galaxy in our galaxy's neighborhood is composed of 99.99 percent dark matter.
Credit for the discovery of this peculiar galaxy has historically gone to the Scottish astronomer James Dunlop.
New Mexico State University astronomer Rene Walterbos is investigating the Evil Eye, a peculiar galaxy that appears to stare back at astronomers like an eyeball.
With my 10-inch scope at 118x, it's more obvious that there are two galaxies here rather than one peculiar galaxy. NGC 2207, the owner of the more obvious core, is about 2' long and two-thirds as wide.
Multi-wavelength observations have been obtained previously for this galaxy and will be analysed in detail, in combination with the GALEV models (see galaxy transformation at intermediate redshift below), to determine the star-formation history of this peculiar galaxy.

NGC 5128, known as Centaurus A, is a bright peculiar galaxy, thought to be a giant elliptical galaxy devouring a dusty spiral.
He described the dozen or so 6th- to 11th-magnitude stars within this 10'-wide open cluster as a "casket of variously coloured precious stones." In Centaurus my eyes feasted on the magnificent naked-eye globular cluster NGC 5139, Omega Centauri, and the giant peculiar galaxy NGC 5128, also known as Centaurus A, which flaunted its famous dust lane.
Perhaps the best-known peculiar galaxy in the autumn evening sky is NGC 520 (Arp 157), a bizarrely warped system in southeastern Pisces.
This peculiar galaxy was elongated along a northeast-to-southwest axis and had a distinctive arrowhead shape.
It was originally classified as a peculiar galaxy based on a condensation about 2.6[cent] east of the galaxy's core that was thought to have been a "galaxy fragment." Because of this, NGC 1023 is included in Halton C.
