This Hubble image shows NGC 1365, a double-barred spiral galaxy 55.4 million light-years away in the constellation of Fornax. The color image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the ultraviolet, near-infrared, and optical parts of the spectrum. The image was made through five filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / J.

The EHT Collaboration unveiled the first direct visual evidence of the supermassive black hole in the center of the elliptical galaxy Messier 87 and its shadow. The shadow of a black hole seen here is the closest we can come to an image of the black hole itself, a completely dark object from which light cannot escape. The black hole’s boundary -- the event horizon from which the EHT takes its name -- is around 2.5 times smaller than the shadow it casts and measures just under 25 billion miles (40 billion km) across.
