Space shuttle and station in silhouette

against the sun; very cool shot.

And here's a couple of amazingly clear shots of the Jupiter impact site from the Hubble. Note this:
The image above is the sharpest yet of the Pacific Ocean–sized impact site,; think of something big enough, moving fast enough, to make a smack that size. Now think of the fact that we never knew it was coming, and if a lucky astronomer hadn't spotted the impact site we might never have known about it.

We need better watchdogs in the system.
