NGC 4214 = NGC 4228 is an irregular galaxy with extensive star formation regions of the Hubble type IBm in the constellation Hounds in the northern sky . It is estimated to be 14 million light years away from the Milky Way and about 30,000 light years in diameter.
The galaxies NGC 4163 and NGC 4190 are located in the same area of ​​the sky .

Many new stars and star clusters are emerging in this galaxy, recognizable by the white-bluish light. Scientists suspect that the massive stars of the star cluster in the center will soon explode as supernovae .

The supernovae SN 1954a (Type Ib) and SN 2010U were observed here.

The object was discovered on April 28, 1785 by the German-British astronomer Wilhelm Herschel .
