Scientists Discover Largest Ever Blackhole 36 Billion Times The Size of Our Sun

August 11, 2025

For decades, astronomers have speculated about the upper limits of black hole size. Now, a new discovery has brought us closer to that theoretical ceiling. Deep within the galaxy SDSS J1148+1930, also known as the Cosmic Horseshoe, researchers have confirmed the presence of an ultramassive black hole weighing in at 36.3 billion solar masses—nearly brushing ...

The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. In coordinated press conferences across the globe, EHT researchers revealed that they succeeded, unveiling the first direct visual evidence of the supermassive black hole in the centre of 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 40 billion km across. While this may sound large, this ring is only about 40 microarcseconds across — equivalent to measuring the length of a credit card on the surface of the Moon. Although the telescopes making up the EHT are not physically connected, they are able to synchronize their recorded data with atomic clocks — hydrogen masers — which precisely time their observations. These observations were collected at a wavelength of 1.3 mm during a 2017 global campaign. Each telescope of the EHT produced enormous amounts of data – roughly 350 terabytes per day – which was stored on high-performance helium-filled hard drives. These data were flown to highly specialised supercomputers — known as correlators — at the Max Planck Institute for Radio Astronomy and MIT Haystack Observatory to be combined. They were then painstakingly converted into an image using novel computational tools developed by the collaboration.

At the core of the galaxy Messier 87 (M87), a cosmic behemoth is challenging preconceptions. Renowned for being the first black hole ever directly photographed, the supermassive black hole M87 has just exposed another amazing secret: it devours matter even faster and spins at a blistering 80% of the maximum speed in the universe. Using ...
