2023年8月14日 · Dreyer lists NGC 4400 as reported by Stoney's employer, William Parsons, but notes that most of his discoveries were actually made by his assistants. Part of galaxy NGC 4395, and close to NGC 4400, which see for images.

NGC 4400 is a Other Classification in the Canes Venatici constellation. NGC 4400 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. The image below is a photograph of NGC 4400 from the Digitized Sky Survey 2 (DSS2 - see the credits section) taken in the red channel. The area of sky ...

NGC 4400 Galaxy Facts. NGC 4400 is a Galaxy located in the constellation of Canes Venatici in the northern hemisphere. NGC 4400 is called NGC 4400 in the New General Catalogue (NGC). This catalogue is a list of deep space objects compiled by John Louis Emil Dreyer in 1888 to update John Herschel's earlier work.

NGC 4395 is a low surface brightness galaxy in constellation Canes Venatici. NGC 4399, NGC 4400 and NGC 4401 are bright HII regions inside the galaxy. In both images NIR (near infrared) is mapped to red, yellow is mapped to green and blue is mapped to blue. In the version with H-alpha that emission line is shown in reddish orange.

NGC 4400 est une nébuleuse en émission située dans la constellation des Chiens de chasse. Cette région HII [2] est située dans la galaxie NGC 4395 et elle a été découverte par le physicien irlandais George Stoney en 1850. La galaxie NGC 4395 renferme deux autres régions HII très brillantes, soit NGC 4399 et NGC 4401.

2023年9月26日 · A chaotic galaxy with several bright ionized hydrogen (HII) regions, three of which received their own NGC designations: NGC 4399, 4400, and 4401. The recessional velocity of 320 km/sec is too small to be a reliable distance indicator, as the peculiar (non-Hubble expansion) velocity for the galaxy could be a substantial portion of the value.
