The Sculptor group is the
nearest group of
galaxies to the Local Group and is dominated by five
galaxies, four spiral - NGC 247, 253, 300 and 7793 and one
irregular - NGC 55.
Subsequently, however, an even more distant quasar with a tentative redshift of z = 6.40 was announced on January 9, 2003,
near the SDSS detection limit of a redshift of z ~ 6.5 for bright quasars, and other teams of astronomers detected even more distant, fast - star - forming
irregular proto -
galaxies, including: gravitationally - lensed HCM 6A behind
galaxy cluster Abell 370 with a redshift of z ~ 6.56, which appears to be converting about 40 Solar - masses into stars annually; (PhysicsWeb; IFA press release; Hu et al, 2002, in pdf; and erratum); and the possible «superwind -
galaxy» LAE J1044 - 0130 (Subaru press release; and Ajiki et al, 2002, in pdf).
