Physicists with MIT and the University of Vienna have conducted an experiment that pretty much proves that the phenomenon of quantum entanglement is real, and not the effect of a "loophole" that could be explained by classical physics. The experiments that were used in closing this loophole involved a combination of Earth-bound telescopes, 30,000 entangled pairs of entangled photons, and starlight nearly as old as the universe itself.

Astronomers at Canada’s University of Calgary have revealed a previously-uncatalogued, purple-colored luminous phenomenon in the sky, found through observations made by citizen scientists, and confirmed by satellite data. The phenomenon consists of a lighted band or ribbon that stretches across the sky, and although it is not actually a new phenomenon, nobody had bothered paying attention to it before now.

And for lack of a better name, the researchers called it ‘Steve’.
