Herschel Space Observatory has shown that galaxies with the most powerful, active, supermassive black holes at their cores produce fewer stars than galaxies with less active black holes in this artist concept.

This image from NASA WISE spacecraft shows a blazar, a voracious supermassive black hole inside a galaxy with a jet that happens to be pointed right toward Earth. Active black holes are often found at the hearts of elliptical galaxies.

This artist concept shows a feeding, or active, supermassive black hole with a jet streaming outward at nearly the speed of light. Such active black holes are often found at the hearts of elliptical galaxies.

RCW 108 is a region where stars are actively forming within the Milky Way galaxy about 4,000 light years from Earth. This image is part of a large collection of images of merging galaxies taken by NASA Hubble Space Telescope.

A range of supermassive black holes lights up this new image from NASA NuSTAR. All of the dots are active black holes tucked inside the hearts of galaxies, with colors representing different energies of X-ray light.

This mosaic reveals a panorama of the Milky Way from NASA Spitzer Space Telescope. This picture covers only about three percent of the sky, but includes more than half of the galaxy stars and the majority of its star formation activity.

This artist concept illustrates the frenzied activity at the core of our Milky Way galaxy. The galactic center hosts a supermassive black hole in the region known as Sagittarius A*, or Sgr A*, with a mass of about four million times that of our sun.
