Haro 11 (H11) is a small galaxy at a distance of 300,000,000 light-years (92,000,000 parsecs)(redshift z=0.020598).[1] It is situated in the southern constellation of Sculptor. Visually, it appears to be an irregular galaxy, as the ESO image to the right shows. H11 is named after Guillermo Haro, a Mexican astronomer who first included it in a study published in 1956 about blue galaxies.[2] H11 is a starburst galaxy that has 'super star clusters' within it and is one of nine galaxies in the local universe known to emit Lyman continuum photons (LyC).[3][4][5][6][7]
