NGC 1744 — SBcd in Lepus
SBcd in Lepus, 5.3 arcminutes across, its light 36 million years old. Measured by HyperLEDA, photographed by Pan-STARRS1. Recorded once.
About NGC 1744
What you are looking at
NGC 1744 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 70° from face-on, so it appears as a long oval. From edge to edge its visible disc spans about 55,000 light-years (taking its redshift distance, which for a galaxy this near is approximate), about half the width of the Milky Way.
What astronomers have recorded
SIMBAD, the reference database astronomers use, classes it as a low-surface-brightness galaxy, its light spread faint and thin. It is cited in 163 scientific papers indexed by SIMBAD, and recorded there under 19 different catalogue designations.
When this light set out
What a telescope records of NGC 1744 is light that left it about 36 million years ago; on Earth, the planet had come through its hottest interval since the dinosaurs. The galaxy is moving away from us at about 742 km/s (1.7 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 1744 sits within the constellation Lepus. It is best placed on winter evenings: around 9:30 pm in January it stands about 24° high in the south, seen from the middle of the United States.
By apparent size it is number 111 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 5.3 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.
