NGC 1510 is a southern E0 galaxy with an A-type spectrum, strong emission lines, and extremely blue colors. It has the relaxed light distribution of a normal elliptical, and there is no sign of interaction with its brighter SBO companion NGC 1512. There is an abnormally large amount of hydrogen in the whole system, while the emission lines in NGC 1510 yield a normal abundance of helium but a deficiency in other elements by a factor 10. The UBV colors and multichannel spectrum scans are well matched to single-burst models with a Salpeter initial mass function and an age of a few hundred million years. It is suggested that NGC 1510 may be a young galaxy that has formed from the large amount of hydrogen near NGC 1512.
