From American Astronomical Society meeting in Seattle:
Keck has found three quasars near each other
Normally we'd expect that this is the lensed image of a single quasar, but they have not been able to fit a lens model to the data.
It is possible that these are three physically associated quasars; which is not that surprising in some way.
We'll see.
Read all about it.

Just to clarify, if ye doesn't mind ...
Keck has found three quasars near each other ...
... and at the same redshift; but, which cannot be adequately explained by a lensing model.

Wow, that is really cool. I do like how George and Keck Observatory are one in the same (you can take the student out of CalTech, but you can't take CalTech out of the student).
