Globular clusters are inherently beautiful objects, but the subject of this NASA/ESA Hubble Space Telescope image, Messier 3, is commonly acknowledged to be one of the most beautiful of them all.Containing an incredible half-million stars, this 8-billion-year-old cosmic bauble is one of the largest and brightest globular clusters ever discovered.

The First-Ever Close-Up of a Black Hole

The first-ever image of a black hole was released Wednesday by a consortium of researchers, showing the "black hole at the center of galaxy M87, outlined by emission from hot gas swirling around it under the influence of strong gravity near its event horizon."

You're looking at the brand-new, first-ever close-up picture of a black hole. This image of the black hole M87 at the center of the Virgo A galaxy is the result of an international, 2-year-long effort to zoom in on the singularity. It reveals. for the first time, the contours of
