I'm still amazed we knew about its existence any time prior, the best picture we had in may is just 9 pixels wide. There's more visual information in Google's favicon.

Shows better the previous best.
> The Hubble images are a few pixels wide. But through a technique called dithering, multiple, slightly offset pictures can be combined through computer-image processing to synthesize a higher-resolution view than could be seen in a single exposure. "This has taken four years and 20 computers operating continuously and simultaneously to accomplish," says Buie, who developed special algorithms to sharpen the Hubble data.
