Number 31 (Story #2), April 26, 1991 by Phillip F. Schewe and Ben Stein A DARK SUPERMASSIVE OBJECT has been found in the galaxy NGC6240. The mass of the object, inferred from the rotational motion of the galaxy (a galaxy which seems to be actually two galaxies in collision), is between 40 and 200 billion times that of the Sun. The Rice-Maryland-Hawaii team that made the discovery (reported in the 10 April Astrophysical Journal Letters) have speculated that the object might be a black hole (and if so, the biggest black hole in the universe) or possibly an accumulation of brown dwarfs or neutron stars.
