About NGC 1179
What you are looking at
NGC 1179 is a late-type spiral: a small central bulge and open, loosely wound arms full of young stars and star-forming gas. It is tilted about 48° to our line of sight, enough to show both the shape of its arms and the depth of its disc. From edge to edge its visible disc spans about 91,000 light-years, close to the width of the Milky Way.
What astronomers have recorded
SIMBAD, the reference database astronomers use, classes it as a low-surface-brightness galaxy, its light spread faint and thin. It is cited in 104 scientific papers indexed by SIMBAD, and recorded there under 19 different catalogue designations.
When this light set out
What a telescope records of NGC 1179 is light that left it about 85 million years ago; on Earth, dinosaurs were at their peak. The galaxy is moving away from us at about 1,778 km/s (4.0 million mph), carried by the expansion of the universe.
Finding it in the sky
NGC 1179 lies in Eridanus. It is best placed on winter evenings: around 9:30 pm in December it stands about 31° high in the south, seen from the middle of the United States.
Its neighbours
At almost the same distance from us, and so its neighbours in space as well as on the sky: NGC 1145 (1.9° away on the sky, at least 2,870,000 light-years from it); NGC 1232 (2.4° away on the sky, at least 3,520,000 light-years from it).
By apparent size it is number 297 of the 12,657 galaxies on the Galaxy Origins register.

What is sold
A print of this galaxy and the record of the calculation, once. When it sells it leaves the register and is not offered again. We assign no names and no ownership — nobody can sell you those.
At 3.7 arcminutes this is a Exceptional galaxy, which is the tier where a real photograph shows clear structure and dust lanes. The tier comes from the measured diameter, not from a price list.
