About NGC 4094
What you are looking at
NGC 4094 is a late-type spiral: a small central bulge and open, loosely wound arms full of young stars and star-forming gas. Its disc is steeply tilted, about 73° from face-on, so it appears as a long oval. From edge to edge its visible disc spans about 88,000 light-years (taking its redshift distance, which for a galaxy this near is approximate), close to the width of the Milky Way.
What astronomers have recorded
SIMBAD, the reference database astronomers use, classes it as an emission-line galaxy: its spectrum shows the glow of gas lit by young stars. It is cited in 81 scientific papers indexed by SIMBAD, and recorded there under 16 different catalogue designations.
When this light set out
The light that reaches us from NGC 4094 today set out about 69 million years ago, when dinosaurs were at their peak. The galaxy is moving away from us at about 1,438 km/s (3.2 million mph), carried by the expansion of the universe. For a galaxy this close, its own motion through space is a large share of that speed, so the distance worked out from it is approximate; distances measured from individual stars in it can differ.
Finding it in the sky
NGC 4094 lies in Corvus. It is best placed on spring evenings: around 9:30 pm in April it stands about 35° 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 4035 (1.9° away on the sky, at least 2,320,000 light-years from it); NGC 4050 (2.0° away on the sky, at least 2,390,000 light-years from it).
By apparent size it is number 173 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 4.4 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.
