Is this actually the first image of dark matter?

What we see in our universe only accounts for roughly five per cent of what’s out there. The remaining 95 per cent is invisible.

But now, a researcher at the University of Tokyo says he's seen at least part of that invisible universe.

It’s believed that roughly 68 per cent of our universe is made up of dark energy, which is causing the universe to expand at an accelerating rate, and the remaining 27 per cent is dark matter, which keeps galaxies from flying apart.

The only problem is, we can’t see dark matter or dark energy: we only see how they interact with other objects, like galaxies.

In 1933, astronomer Fritz Zwicky wondered why galaxies in a cluster weren't flying away from one another, based on ordinary matter. He proposed that there was an invisible form of matter holding them t
