Astronomers working with NASA's Nuclear Spectroscopic Telescope Array (NuSTAR) have found a pulsating dead star beaming with the energy of about 10 million suns.

The black hole -- known as P13 -- lies on the outskirts of the galaxy NGC7793 about 12 million light years from Earth and is ingesting a weight equivalent to 100 billion billion hot dogs every minute.
