Nearby Galaxy Boasts Two Monster Black Holes, Both Active
"At the hearts of most large galaxies, including our own Milky Way, lies a supermassive black hole weighing millions of times the sun's mass," said Michael Koss, the study's lead author at NASA's Goddard Space Flight Center in Greenbelt, Md., and the University of Maryland in College Park (UMCP). "Some of them radiate billions of times as much energy as the sun."

Astronomers refer to galaxy centers exhibiting such intense emission as active galactic nuclei (AGN). Yet as common as monster black holes are, only about one percent of them are currently powerful AGN. Binary AGN are rarer still: Markarian 739 is only the second identified within half a billion light-years.

1. So is there a goldilocks zone somewhere off in the distance, far enough away,
that is created by all this energy? Are there any planets that face the inner galaxy and actually receive that energy in just the right dose to bring them alive?
