NGC 5394 is a barred spiral galaxy located in the constellation Canes Venatici. Its speed relative to the cosmic microwave background is 3,639 ± 14 km/s, which corresponds to a Hubble distance of 53.7 ± 3.8 Mpc (∼175 million ly). [1] NGC 5394 was discovered by German-British astronomer William Herschel in 1787.

NGC 5395 is an interacting spiral galaxy located at a distance of 160 million light years, but receding away from the Earth at 3511 kilometers (2181.6 miles) per second, in the constellation Canes Venatici. It was discovered by William Herschel on May 16, 1787.

NGC 5394/5: Image taken with the Gemini 8-meter telescope on Maunakea Physical Properties. NGC 5395 is a Seyfert Type II spiral galaxy. It is interacting with the smaller companion NGC 5354 which shows two open tidal arms and also starburst activity in its centre region.

Two galaxies, NGC 5394 and NGC 5395, slowly whirl about each other in a gravitational interaction that sets off a flourish of sparks in the form of new stars. The featured image, taken with the Gemini North 8-meter telescope on Maunakea, Hawaii, USA, combines four …

2000年7月8日 · NGC 5394 [the smaller galaxy to the north] has prominent inner and outer spiral arms (the inner arms appear as a nearly complete central circle). The inner spiral arm system smoothly joins the outer system. The companion galaxy NGC 5395 has several dark dust lanes, and knotty spiral arms.

1999年10月1日 · Despite the presence of H I gas, two of the three optically bright inner spiral arms of NGC 5394 show no evidence of ongoing star formation. A galaxy encounter simulation reproduces some of the main features of this system with a collision that is prograde relative to NGC 5394 and retrograde at a high tilt angle relative to NGC 5395.

NGC 5394, has inner spiral arms (see Fig. 1) described by Arp (1969) and Wray (1988) as unusual, mostly smooth, high surface brightness arcs, near its sharp, very bright nucleus and two long, fairly symmetric, open tidal arms. The nucleus of NGC 5394 is a strong radio continuum source in the FIRST survey (Becker, White, & Helfand

2019年12月13日 · Few are as captivating as the galactic duo known as NGC 5394/5, sometimes nicknamed the Heron Galaxy. This image, obtained by the Gemini Observatory of NSF's National Optical-Infrared Astronomy...

A galaxy encounter simulation reproduces some of the main features of this system with a collision that is prograde relative to NGC 5394 and retrograde at a high tilt angle relative to NGC 5395. The model finds that the inner spiral structure of NGC 5394 developed from an eye-shaped (``ocular'') structure at slightly earlier times.
