I thought this latest from NuSTAR was cool....

Giving the finger to the other side of the universe.

Albert would be so happy to see the light bending as he so accurately predicted

What the modern-day gravitational lensing helps with is the characterization of the elusive dark matter. Every observed lens tells us a little bit about the ratio of dark to ordinary matter in the lensing galaxy and sometimes also something about the distribution of dark matter.

I'm not so sure about that, my understanding is the theory was that a mass large enough could actually bend light so an observer here on Earth would see 2 objects. in the 80s this was confirmed by telescopic observation. what at first appeared to be a halo or corona surrounding or behind a star or galaxy in fact was actually very far behind it.....the light emitted from the distant one was actually bending around the nearer star creating the illusion. there must be dark matter, nothing else explains so much but I'm yet to find evidence proving it's existence........if you have fresh information please enlighten me.

The bullet cluster seems to be the most convincing astronomical evidence for dark matter to date.

Locally, CERN has not turned up anything yet, AFAIK.
