    SUMMARY: Astronomers are finding supermassive black holes at the heart of nearly every galaxy they look at, and these monsters range in size depending on the size of their host galaxy. An international team of astronomers has turned up what seems to be the smallest supermassive black hole so far - only a million times the mass of our Sun - located at the centre of galaxy NGC 4395. Supermassive black holes can often be 100 times this mass, and NGC 4395 is one of a family of galaxies which tend to have very large black holes.

    It is interesting to hear this thing referred to as the runt of the litter, and all that. This SMBH is about one third the size of the one in the Milky Way, Sgr A*. What does that say about us?

    I guess that closer examination of NGC 4395 will reveal a recent small merger has taken place, and that this galaxy only recently, has an AGN.
