# Locations of farthest matter

Regarding matter that has the highest redshifts, do we see such matter in every general direction we look (relative to Earth: up down left right front back)?

• Yes we do, and it looks like this. – pela Apr 19 '16 at 13:22
• That's CMB levels. I want redshifts. – Paul Apr 19 '16 at 13:25
• The CMB is all at the same redshift (~1100), to a relative precision within $10^{-5}$, no matter if you look up, down, left, or right. We haven't observed anything with higher redshifts. – pela Apr 19 '16 at 14:23
• So if the measured CMB peak wavelength is ~2mm, then the originating CMB was ~2mm/1100 (~2um)? – Paul Apr 19 '16 at 15:21
• More or less, yes. The answer depends a bit on whether you express intensity as a function of wavelength or frequency. I think 1 $\mu$m is considered the peak wavelength – pela Apr 20 '16 at 9:07
