Now that's BIG


Too old to watch the Asian races live.
Astronomers have just discovered the largest thing in the universe (so far)--a large quasar group (LQG) that extends 4 BILLION light years across. That is over 3 times larger than current cosmological theory says should be able to exist!

There are numerous stories on line about it. Just Google "Large Quasar Group" and go from there.

Just to give an idea of how enormous that is, the Milky Way is 100,000 light years across, and the galaxy nearest to us is 2.5 million light years away.
Actually as per your suggestion siffert_fan I have read up on it and it's size is mind boggling 1200 Megaparsecs at it's widest when the boffins thought the largest structure could be no more than 370 Megaparsecs across, and if that thing represents a galactic nuclie then what size is the galaxy it is the centre of?
Of course it's not quite accurate to say this IS the largest structure in the universe to have been identified so far. Like everything else in the universe when we look into distant objects and quasars in particular we are also looking back in time.
That structure they've just detected has probably went a very long time ago indeed.
