The NYTimes is running a nice collection[1] of the jaw-dropping photos of the comet from Rosetta over the course of the mission, including some from the past month, and the spectacular close fly-by in March.

As many faraway and strange places as we've explored in the Solar System so far, something about this comet – roughly the breadth of Central Park, yet with untold nooks and crannies – feels more coldly alien than anything else I've seen.
