Event Horizon Telescope Captures First Image of Black Hole

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.

Astronomers using the Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes (ALMA, APEX, the IRAM 30-m telescope, the James Clerk Maxwell Telescope, the Large Millimeter Telescope Alfonso Serrano, the Submillimeter Array, the Submillimeter Telescope, and the South Pole Telescope) — have obtained the first image of a black hole, using EHT observations of the center of Messier 87, a giant elliptical...

This Hubble image shows the globular cluster Messier 3. The color image was made from separate exposures taken in the visible and ultraviolet regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Five filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

This is a composite picture showing images of storms on Neptune from Hubble (left) and Voyager 2 (right). The Hubble image shows a new dark storm (top center). In the Voyager image, a storm known as the Great Dark Spot is seen at the center. It is about 8,000 miles by 4,100 miles (13,000 km by 6,600 km) in size -- as large along its longer dimension as the Earth. The white clouds seen hovering in the vicinity of the storms are higher in altitude than the dark material. Image credit: NASA / ESA / Hubble / GSFC / JPL.

The ‘Teacup’ quasar is causing an ongoing storm. The ‘handle’ is a ring of X-ray (blue) and optical (red and green) light surrounding a giant bubble, shown in the Chandra and Hubble data. This handle-shaped feature, which is located about 30,000 light-years from the galaxy’s central supermassive black hole, was likely formed by one or more eruptions powered by the black hole.
