Fulfilling a prediction of Einstein’s theory of General Relativity, researchers report the first-ever recordings of X-ray emissions from the far side of a black hole.

An international collaboration aims to create a 3D map of the universe, unraveling the mysterious nature of dark energy.

SLAC cosmologists are using multiple images of the same quasars, produced by massive galaxies’ gravitational pull, to calibrate cosmic distances. Their work may help resolve long-standing debates about how quickly the universe is expanding.
