About NGC 2835
What you are looking at
NGC 2835 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 56° 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 79,000 light-years (taking its redshift distance, which for a galaxy this near is approximate), about 81% of the Milky Way’s width.
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 300 scientific papers indexed by SIMBAD, and recorded there under 19 different catalogue designations.
When this light set out
The light that reaches us from NGC 2835 today set out about 43 million years ago, when the planet had come through its hottest interval since the dinosaurs. The galaxy is moving away from us at about 886 km/s (2.0 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
In the sky, NGC 2835 sits within the constellation Hydra. It is best placed on spring evenings: around 9:30 pm in March it stands about 28° high in the south, seen from the middle of the United States.
By apparent size it is number 64 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 6.4 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.
