# astro: the first picture of a black hole at the heart of galaxy Messier 87.

<< We have taken the first picture of a black hole, (..) This is an extraordinary scientific feat accomplished by a team of more than 200 researchers. (..) We have achieved something presumed to be impossible just a generation ago, (..)  Breakthroughs in technology, connections between the world's best radio observatories, and innovative algorithms all came together to open an entirely new window on black holes and the event horizon. >> Sheperd S. Doeleman

<< This breakthrough was announced today in a series of six papers published in a special issue of The Astrophysical Journal Letters.  >>

<< The telescopes contributing to this result were ALMA, APEX, the IRAM 30-meter telescope, the James Clerk Maxwell Telescope, the Large Millimeter Telescope Alfonso Serrano, the Submillimeter Array, the Submillimeter Telescope, and the South Pole Telescope. Petabytes of raw data from the telescopes were combined by highly specialised supercomputers hosted by the Max Planck Institute for Radio Astronomy and MIT Haystack Observatory. >>
