I failed to mention before I did see "Children of Men" a couple weeks back, making the trek on bus to Cedar Falls, where all interesting films roost for a week or so. I loved the film, top to bottom, and today I found an absolutely fantastic post regarding it at the Valve, which in turn is part of a larger series of posts about the apocalypse in writing. That discussion is also part of a larger dialogue around the web that's been going on in recent days. All of it is very worthwhile reading, so check it out. Lots of food for thought.
Read Ben's review of the film, and also the Strange Horizons review.
The Hubble Space Telescope went blind.
Neptune may have literally thousands of escorts following it through space. The most interesting part about this is what it suggests about the planet's early history: it may have been like a snowball drifting through the outer solar system, picking up material (Triton?) and interacting with other objects (Pluto?).
