The first ever 'picture' of the black hole at the center of the Milky Way galaxy, Sagittarius A*.
Obviously, a black hole can't really be photographed. "And still, we are not truly seeing Sagittarius A*, not really. Astronomers can’t take a real picture—in the way us non-astronomers would consider it—because black holes are, by definition, invisible. So the photo released today doesn’t show the black hole itself. Astronomers have captured Sagittarius A* in silhouette. The image reveals the shadow that the immensely dense black hole casts against the glowing cosmic gas swirling around it. Like the black hole in M87, Sagittarius A* resembles a donut."
