Black holes can form spiraling pairs in three different ways, the gravitational waves from hundreds of collisions suggest

A Nearby Black Hole as a Window into the Early Universe

An international team led by researchers at the Max Planck Institute for Radio Astronomy (MPIfR) has discovered a nearby galaxy whose central black hole is undergoing an extraordinary, long-lasting radio outburst unlike anything previously observed. Although located just 1.8 billion light-years away, the rapidly growing, low-mass black hole exhibits properties expected for black holes in the early Universe, making it a unique local laboratory fo…
