NGC 6240 A giant gas cloud spanning 300,000 light years with a mass of 10 billion Suns inside the galaxy merger system NGC 6240. This collision involves two spiral galaxies about the size of the Milky Way, each containing a supermassive black hole in the center, which are on their way to form an even more massive black hole.

Colliding galaxies | #NGC6240A giant cloud of gas spanning 300,000 years light with a mass of 10 billion suns into the system merging galaxies NGC 6240. This collision involving two spiral galaxies the size of the Milky Way, each with a supermassive black hole at the center, they are on track to form an even more massive black hole.
In August of 2007, astronomers located a gigantic hole in the universe. This empty space, stretching nearly a billion light-years across, is devoid of any matter such as galaxies, stars, and gas, and neither does it contain the strange and mysterious dark matter, which can be detected but not seen. The large void in the Constellation Eridanus appears to be improbable given current cosmological models. God told Job He was beyond the empty space... The Book of Job in the Holy Bible
At the centre of every large galaxy lives a giant black hole that swallows gas or dust clouds that stray too close. As matter spirals inwards, it is compressed into an accretion disk. By the time it falls into the black hole, the matter is so hot that much of its mass is converted to energy, which emerges as heat, light and jets of high-energy particles.
Milky Way’s second-largest black hole? Astronomers are calling it a possible first detection of an intermediate-mass black hole, a missing link in black hole evolution. 1/20/16 Artist’s impression of the clouds scattered by an intermediate mass black hole.

Biggest Black Hole Blast Ever Could Solve Cosmological Mystery
Nahum Arav, an astrophysicist at Virginia Tech, observed a quasar, called SDSS J1106+1939, about 13.7 billion years of age. Instruments revealed a giant cloud of hot, ionized gas that was blasted away from the galaxy at nearly 5,000 miles per second (8,000 kilometers per second), or about 2.6 percent the speed of light. The gas is mostly hydrogen with some helium and traces of other elements such as carbon.The energy needed to fire that blast is five times greater than any known quasar.
