The event horizon of a nonspinning billion-solar-mass back hole has a radius of 1.8 billion miles — the distance of Uranus from the Sun.

Researchers have used radio observations of rapidly spinning neutron stars to search for signals from supermassive black hole pairs at the dawn of galaxy formation.
