NGC 1073 is a bar-spiral galaxy of the Hubble type SBc in the constellation Whale (Cetus) south of the ecliptic . It is estimated to be 54 million light-years from the Milky Way and about 80,000 light-years across. The galaxy has an angular extent of 4.9 '× 4.5' and an apparent magnitude of 10.8 mag.
In the same area of ​​the sky are u. a. the galaxies NGC 1038 , NGC 1043 , IC 1827 .

At the top left of the Hubble image (below), there is an approximately circular region. This is an area in which new stars have just formed. Hidden in the structure is a bright X-ray source called IXO 5 , which was discovered by NASA's Chandra X-ray telescope in 2012 . This is presumably a black hole orbited by a normal star .

The Type Ic supernova SN 1962L was observed here.

The object was discovered by William Herschel on October 9, 1785 .
