NGC 1325 — SBbc in Eridanus
SBbc in Eridanus, 4.3 arcminutes across, its light 76 million years old. Measured by HyperLEDA, photographed by Pan-STARRS1. Recorded once.
About NGC 1325
What you are looking at
NGC 1325 is a spiral of the same broad class astronomers give the Milky Way: a moderate bulge and clearly drawn arms. 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 74° from face-on, so it appears as a long oval. From edge to edge its visible disc spans about 96,000 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. Two supernovae have been recorded in it, the first in 1975; the most recent include SN 1975S, SN 2021yja. It is cited in 182 scientific papers indexed by SIMBAD, and recorded there under 22 different catalogue designations.
When this light set out
What a telescope records of NGC 1325 is light that left it about 76 million years ago; on Earth, dinosaurs were at their peak. The galaxy is moving away from us at about 1,589 km/s (3.6 million mph), carried by the expansion of the universe.
Finding it in the sky
In the sky, NGC 1325 sits within the constellation Eridanus. It is best placed on winter evenings: around 9:30 pm in December it stands about 28° 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 1325A (0.2° away on the sky, at least 300,000 light-years from it); NGC 1315 (0.3° away on the sky, at least 460,000 light-years from it); NGC 1332 (0.5° away on the sky, at least 640,000 light-years from it); NGC 1347 (1.4° away on the sky, at least 1,890,000 light-years from it), and 7 more.
By apparent size it is number 184 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 4.3 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.
