, 02:28, January 31, 2012→39 billion light years away?
:::::::::::::Nobody's observed them. The most distant object anyone has ever observed is the galaxy UDFj-39546284, which - if it still exists, which is unlikely - is 31.7 billion light years away and is now way outside the observable universe. The light from it has travelled 13.2 billion light years to get to us. --[[User:GeorgeLi|GeorgeLi]] 21:22, 30 January 2012 (EST)

::::::::::::::And that's 31.7 billion light years comoving distance, 13.2 billion light years in light travel distance. Meaning, we see it as it was, billions of years ago, and it is WAY farther away by now. [[User:RachelW|RachelW]] 21:25, 30 January 2012 (EST)

Aschlafly has "numerous references" to stars 39 billion light years away. I have an open mind about this, and I trust that as an educator he will want to share them. [[User:ScottDG|ScottDG]] [[User talk:ScottDG|Talk]] <b>2 billion lightyears ago...wait, what? </b> 21:28, 30 January 2012 (EST)
