CHICAGO — For decades, the photo archive of Ebony and Jet magazines has been difficult to access and largely mysterious to scholars, an elusive treasure trove of more than four million prints and negatives that documented the lives of African-Americans. That collection could soon be opened to the public after an auction on Wednesday in Chicago. Leaders of the foundations — the Ford Foundation, The J.

From Earthrise to the black hole: astronomy's most famous images
The picture shows a halo of dust and gas, tracing the outline of a colossal black hole, at the heart of the Messier 87 galaxy, 55m light years from Earth. The equations predicted that, beyond a certain threshold, when too much matter or energy is concentrated in one place, space and time collapse, leaving behind a sinkhole through which light and matter can enter but not escape. At first these were thought to be mathematical oddities, rather than real astronomical objects, but in the past century overwhelming evidence has confirmed that black holes are out there. The edge of the black hole is defined by its so-called event horizon. This is the point at which escaping would require something to travel at faster than the speed of light — which as far as we know nothing does — so it is the point of no return.
In the century since Einstein predicted the existence of black holes in his theory of gravity, astrophysicists have turned up overwhelming evidence for the things. On Wednesday, astrophysicists announced they had captured the first-ever image of a black hole. The picture, taken over five days of observations in April using eight telescopes around the world by a collaboration known as the Event Horizon Telescope, depicts luminous gas swirling around a supermassive black hole at the center of M87, a galaxy 54 million light-years away. The event horizon is the edge of the spacetime abyss, where gravity is so strong that no light can escape from it. This black hole is about 6. It took eight different telescopes to image it. The telescopes collected observational data that was synced with the precision of a billionth of a second. But they still needed good weather at all eight of their telescope sites to see the black hole. To minimize the chance of rain, they built the telescopes in dry regions, including the South Pole and the Atacama Desert in Chile.
