The name of this galaxy is based on a Redshift (z) measurement of nearly 7 (actually, z = 6.604). [ 5 ] Galaxy Cosmos Redshift 7 is reported to be the brightest of distant galaxies (z > 6) and to contain some of the earliest first stars ( first generation ; Population III ) that produced the chemical elements needed for the later formation of ...
The proper distance provides a measurement of how far a galaxy is at a fixed moment in time. At the present time the proper distance equals the comoving distance since the cosmological scale factor has value one: a ( t 0 ) = 1 {\displaystyle a(t_{0})=1} .

Determining past and future positions relies on accurate astrometric measurements of their parallax and total proper motions (how far they move across the sky due to their actual velocity relative to the Sun), along with spectroscopically determined radial velocities (their speed directly towards or away from us, which combined with proper ...
