Marco Mignoli is an Italian astronomer at the National Institute of Astrophysics in Bologna, Italy.

He led a team of astronomers who discovered a billion-solar-mass supermassive black hole in the early universe that is surrounded by at least six protogalaxies. Their findings were published in Astronomy & Astrophysics magazine.

Their decade-long research was conducted using some of the largest telescopes in the world including the Hubble Space Telescope, the European Southern Observatory's Very Large Telescope in Chile and the Keck II telescope on Mauna Kean in Hawaii.

They observed the quasar SDSS J1030+0524 which had a redshift of 6.31. This corresponds to a distance of 12.9 billion light-years or when the universe was only 900 million years old
