"Galaxies may hail from early universe" (SN: 2/16/08, p. 100) was obscure about the brightness of one group of distant galaxies observed by a team that includes Richard Ellis and Johan Richard of the California Institute of Technology. The story implied that these gala:des appear faint because gravitational magnification of their light by foreground galaxy clusters was less than that for another distant galaxy, A1689-zD1, which is unusually (intrinsically) bright.

In fact, the dimness is intrinsic, as the magnification was roughly the same for the faint group and A1689-zD1.
