Most distant things - Simple English Wikipedia, the free encyclopedia

Composite image of five galaxies clustered together just 600 million years after theBig Bang.[1]

This article lists the most distant things known to us, all of which are galaxies or energy sources inside galaxies. Their distances are described in two ways. redshift = z, and billion light years (Gly).

As of 2012, there are only about 50 possible objects z=8 or farther, and another 100 z=7 candidates.[2] Candidates vary in their notability,[2] so not everything is included here. 1 Gly = 1 billion light-years = 109 ly.
