TON 618
Ultra-Massive Black Hole Simulation
Unimaginable Mass
TON 618 contains a supermassive black hole with a mass of approximately 40.7 billion solar masses—more massive than all the stars in the Milky Way combined.
Hyperluminous Quasar
Shining with a luminosity 140 trillion times that of our Sun, TON 618 is one of the brightest objects in the known universe, outshining entire galaxies.
Ancient Light
Located 18.2 billion light-years away, the light we observe from TON 618 was emitted when the universe was only about 10.4 billion years old.
Colossal Event Horizon
The event horizon of TON 618 has a diameter of approximately 390 billion kilometres—over 40 times the distance from the Sun to Neptune.
Lyman-Alpha Blob
TON 618 is surrounded by a massive cloud of hydrogen gas spanning 330,000 light-years—more than twice the size of the Milky Way galaxy.
Beyond Reach
Due to the expansion of the universe, TON 618 is beyond the cosmic horizon we could ever reach, even travelling at the speed of light.
