>I saw that article too. But did we send a probe by Pluto? Why didn't it spot the other moons?
I think Voyager 2 went to Jupiter, Saturn, Uranus and Neptune - they happened to be in a more or less convenient allignment - but not to Pluto, which is very far off the Ecliptic.
The recent moons must have been discovered either from ground-based telescopes, or telescopes orbiting Earth.
