NGC 1448

NGC 1448 or NGC 1457 is an unbarred spiral galaxy seen nearly edge-on in the constellation Horologium. It is at a distance of 55 million light years from Earth. It was discovered by John Herschel in 1835.

From the spectral analysis of SN 2001el, over a dozen diffuse interstellar bands were discovered in NGC 1448 – one of the few cases that these bands were observed outside of the Milky Way. However, the bands were significantly weaker at SN 2003hn.

In January 2017 it was announced that evidence for a supermassive black hole in NGC 1448 had been found in the center of the galaxy.

The galaxy belongs to the NGC 1433 group, part of the Doradus cloud of galaxies.
