They've seen the invisible...

Researchers at Cardiff University in the U.K. have discovered a galaxy made up primarily of dark matter. As it states on their web site, "(Cardiff)...astronomers has discovered an object that appears to be an invisible galaxy made almost entirely of dark matter — the first ever detected. A dark galaxy is an area in the universe containing a large amount of mass that rotates like a galaxy, but contains no stars. Without any stars to give light, it could only be found using radio telescopes."

Here's another good article on the BBC News site.

My only sadness about the finite life I'm living right now...is that the closest I'll get to galactic (or intergalactic) travel is Star Trek.
