IC 2995 — SBc in Hydra
SBc in Hydra, 3.4 arcminutes across, its light 89 million years old. Measured by HyperLEDA, photographed by Pan-STARRS1. Recorded once.
About IC 2995
What you are looking at
IC 2995 is a late-type spiral: a small central bulge and open, loosely wound arms full of young stars and star-forming gas. A bar of stars runs straight across its centre, as one does across the centre of the Milky Way. Its disc is steeply tilted, about 80° from face-on, so it appears as a long oval. From edge to edge its visible disc spans about 86,000 light-years, 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. One supernova has been recorded in it: SN 2019vsa. It is cited in 73 scientific papers indexed by SIMBAD, and recorded there under 17 different catalogue designations.
When this light set out
What a telescope records of IC 2995 is light that left it about 89 million years ago; on Earth, dinosaurs were at their peak. The galaxy is moving away from us at about 1,847 km/s (4.1 million mph), carried by the expansion of the universe.
Finding it in the sky
IC 2995 lies in Hydra. It is best placed on spring evenings: around 9:30 pm in April it stands about 22° 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 4106 (1.8° away on the sky, at least 2,840,000 light-years from it); IC 764 (2.0° away on the sky, at least 3,150,000 light-years from it).
By apparent size it is number 397 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 3.4 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.
