About NGC 2935
What you are looking at
NGC 2935 is a spiral with a sizeable central bulge and well-defined arms, close in type to the Milky Way. It is tilted about 43° 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 132,000 light-years, about 1.3 times the width of the Milky Way.
What astronomers have recorded
SIMBAD, the reference database astronomers use, classes it as a Seyfert galaxy: its nucleus is lit by gas falling into its central black hole, though dust hides part of that glow from us. Three supernovae have been recorded in it, the first in 1975; the most recent include SN 1975F, SN 1996Z, SN 2021mwj. It is cited in 136 scientific papers indexed by SIMBAD, and recorded there under 25 different catalogue designations.
When this light set out
The light that reaches us from NGC 2935 today set out about 109 million years ago, when the first flowering plants had appeared. The galaxy is moving away from us at about 2,274 km/s (5.1 million mph), carried by the expansion of the universe.
Finding it in the sky
In the sky, NGC 2935 sits within the constellation Hydra. It is best placed on spring evenings: around 9:30 pm in March it stands about 29° 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 2983 (1.7° away on the sky, at least 3,310,000 light-years from it).
By apparent size it is number 209 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 4.2 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.
