Astronomy & Space - July 2007

I've been doing some reading lately and am very interested in dark matter. Can someone give me a very brief explanation of what exactly dark matter is believed to be and who are some of the scientists who have introduced us to our, albeit limited, understanding of the subject.

Hey I live on the edge of a city and the light pollution around my area is not severe,but it's not really contributing to my astronomy either lol.But I was looking out of my window and I have actually seen two constellations!,the constellation Ursa Major and Bootes!,I made out Ursa Major by starting with the tail and working my way down the line of stars with the help of identifying each with Stellarium, it's pretty awesome and shocking in a way that each star is 55,0000 light years away in space!,then I had a treat in finding another constallation, yep I navigated south +30 degrees using my skill of Azimuthal Grid and found the Constallation of Bootes, and at the bottom Arcturus! however my question is involved in the constellation Ursa Major, -0(just above) there are two nebulas called Bode's Nebulae and M101,has any of you Astronomers seen these Nebulaes through your telescope?
