Alignment of galaxies millions of light years away supports general relativity
Scientists from research institutions including Kyoto University have confirmed that the intrinsic alignments of galaxies have characteristics that allow it to be a powerful probe of dark matter and dark energy on a cosmological scale.

Nice work.
