The fact that an amateur astronomer named Mike Weasner was able to take a photograph of Jupiter and its moons is hardly something worth a mention on Crave, but the fact that he did it with his iPhone camera is rather remarkable.
It was aimed through a telescope to create a 267x magnification. He then cleaned it up in aperture on a Mac and posted it to Mac Observer.
Before you rush out and try to duplicate the image, you should know that you've got to have perfect conditions and fairly expensive gear. Still, it's incredible that a 2-megapixel, fixed-focus camera can see more than 500 million miles.
