A new investigation into an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, has revealed that these objects are not entirely what they seem. CSOs are active galaxies that host supermassive black holes at their cores. Out of these monstrous black holes spring two jets traveling in opposite directions at nearly the speed of light. But in comparison to other galaxies that boast fierce jets, these jets do not extend out to great distances—they are much more compact.
At the heart of a far-off galaxy, a supermassive black hole appears to have had a case of the hiccups. Astronomers from MIT, Italy, the Czech Republic, and elsewhere have found that a previously quiet black hole, which sits at the center of a galaxy about 800 million light years away, has suddenly erupted, giving off plumes of gas every 8.5 days before settling back to its normal, quiet state.

Astronomers have charted the largest-ever volume of the universe with a new map of active supermassive black holes living at the centers of galaxies. Called quasars, the gas-gobbling black holes are, ironically, some of the universe's brightest objects.
Scientists captured a new image of the supermassive black hole Sagittarius A . The team observed strong magnetic fields around the edge of the black hole. READ MORE: Astronomers revealed
The map logs the location of about 1.3 million black holes, including the furthest that was shining bright when the universe was only 1.5 billion years old, report experts at New York University.
A striking new image of the supermassive black hole at the center of our galaxy has revealed the strong magnetic field that surrounds it, twisting and turning like a spiral. It’s a never-before-seen view of Sagittarius A (or Sgr A ), the immense black hole at the Milky Way’s core that gobbles up nearby light and matter. The image suggests there are structural similarities between this black hole and one at the heart of a galaxy called M87. That black hole — the first ever imaged — is more than...

Blame it on a smaller orbiting black hole repeatedly punching through the accretion disk.
Astronomers have revealed that a brilliant supermassive black hole is not living up to expectations. Although it is responsible for high levels of radiation and powerful jets, this giant black hole is not as influential as many of its counterparts in other galaxies.
