Talk:ISOHDFS 27

"ISOHDFS 27 is the most massive spiral galaxy known so far. It is approximately 6 billion light years from Earth. It has a mass of 1.04×10^12 solar masses (M☉), about four times as massive as the Milky Way."

This is strange, because apparently low end of milky way's estimated mass is 5.8×10^11 solar masses (M☉), and range suggested by mathematical model (which includes the mass of dark matter) is 1-1.5×10^12 M☉

wouldn't that make this galaxy about equal to milky way???
