Actually, while on this topic, I found another picture to show you guys...this time a poster of the Hubble Deep Field.
Basically, the Hubble found this small area above the Big(?) Dipper - the box in the bottom-most photo. In that one box alone, it found so many stars invisible to the eye - thats the second photo. But, this wasn't enough for the good folks at Hubble. They found a relatively empty region of space in that photo and took the main (biggest) photo. Those are freakin' GALAXIES the hubble found. Assuming that region around the Big Dipper represents a typical distribution of galaxies in the sky, well, look how small the main photo is in comparison with the Big Dipper. Then think about how small a part of the sky the Big Dipper is. Then think about how not all of the sky is visible from your location on Earth. Then think about how small the main photo is in comparison with the Big Dipper again.
Yeah, theres quite a lot of galaxies out there. Theres even more matter out there that hasn't formed into a galaxy yet and just stays as enormous clouds of dust out there (search for the Starbirth in Serpens hubble picture). Point being, I still can't imagine that they've counted the number of electrons out there.
