A Haro galaxy is a blue galaxy similar to a Markarian galaxy, often elliptical or lenticular in form, whose spectrum shows bright, sharp emission lines. The emission may be from an active galactic nucleus or from a recent burst of star formation. These galaxies are named after Guillermo Haro, who discovered them in 1956.
