A global team of radio astronomers think they might have found the youngest black hole or neutron star approximately 30 million light-years from Earth. A supernova in exactly the same location was found to have exploded some time around 1983, and subsequent observations have found a brightly-emitting object at the very centre of the supernova remnant. They still can't tell if it's actually a black hole, or just a neutron star or pulsar, so further measurements will be required.
