SUMMARY: When supernova 1987A blew up in the Large Magellanic Cloud, it was the closest supernova in over 300 years, and a great opportunity to study this rare occurrence close up. A neutron star or black hole should have formed at the centre of the expanding ring of debris, but so far, nobody can find it. A neutron star could be there, but it just isn't emitting any radiation, or sucking in any material from its surroundings, so it's invisible from here. If the neutron star had an accretion rate of even 1/5th the mass of the Moon every year, we'd be able to detect it.
