That ring we see in the pic at the link, that's not dark matter we're looking at... it's the light bending around the dark matter, due to the gravitational effects of the dark matter.
It's pretty wild stuff because scientists have theorized about it for a long time... basically saying that there is not enough gravity between the planets, sun & etc for everything to be holding together and not drifting apart -- so there must be *something* that provides the additional gravity needed for the calculations to work.
When you were taking astronomy at college, was dark matter discussed much?

Yeah we touched the subject a little, Our main study was of the planets what their composition was and where they were. My teacher then had his own theories about the rouge planets so we also studied that alot.
we were out looking through the telescope alot searching for random stuff that popped up and had to research and write a paper about it.
