The key to those sharper pics, it seems, is so-called "dark field microscopy, " a technique that, as NewScientist points out, is normally used by biologists.

ENGADGET: X-rays get boost from "dark field" technology

They predict that about 73% of the Universe is made up of dark energy - a pervasive energy field that acts as a sort of anti-gravity to stop the Universe from contracting back in on itself.

BBC: Dark Matter: Experiment to shed light on dark particles

That's because as the Earth moves around the Sun, it is moving into a stationary field of dark matter - and for half the year it will be moving against the tide of dark matter - just like driving into the rain.
