Is it possible to directly observe dark matter?

Just so happen i was able to watch a show on BBC about astronomy (cosmic collisions and evolution of galaxies). They say that dark matter surrounds every galaxies and prevents the galaxies from breaking apart. My question is wouldn't they be able to directly observe those dark matter and idenfiy them during collisions of galaxies, surely the light of these galaxies would illuminate some of the surrouding areas of the galaxies (supposed location of the dark matter)?

PS: I am not studying astronomy. I'm just curious.
 
Currently that's one of the major problems of astro-physics. They might be able to observe it if they knew exactly what it was. There are some hopeful theories but nothing definitive that I know of (i.e. nothing producing hard evidence.)

Dark energy and dark matter is the way some people say that according to most of what we know, there's a whole lot of stuff missing in the Universe. It's believed to be there mostly because current physics models show that either something is there that we can't directly detect or a lot of what we know is wrong... more or less.
