Distance vs. light travel time edit

"the light left the quasar more than 12 billion years ago (it is 12 billion light-years from Earth)."

How can this possibly be correct for a high-redshift object? If the light took 12 billion years to get here, the object must be much further away than 12 Gly since the universe has expanded by several factors since the light was emitted.

Yes, but remember everything in the universe is moving along with the expansion! We are all along for the ride, my friend. — Preceding unsigned comment added by 216.201.236.34 (talk) 14:52, 13 June 2014 (UTC)Reply

It's so called light-travel distance and I know it's confusing :( Co-moving distance is much bigger as you say. Mithoron (talk) 11:06, 19 November 2014 (UTC)Reply

quasar or galaxy? edit

intro paragraph, first sentence,

APM 08279+5255 is a very distant, broad absorption line quasar located in the constellation Lynx.


Galactic structure, 2nd paragraph, 1st sentence,

From these observations APM 08279+5255 is a giant elliptical galaxy with large amounts of gas and dust and an active galactic nucleus (AGN) at its core.

i'm confused.. is that second sentences missing an in? i.e. APM 08279+5525 is in a giant elliptical galaxy... ∈sensorsweep 00:07, 19 November 2014 (UTC)Reply
