NGC 1448 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 British astronomer John Herschel on 24 October 1835. [2] Herschel observed the galaxy again on 14 December 1835, resulting in it being listed twice in the New General Catalogue, as NGC 1448 and as NGC 1457. [2]

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. [3]
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. [4]
The galaxy belongs to the NGC 1433 group, [5] part of the Doradus cloud of galaxies.
