APOD 2.5

The image below is an illustration of a black hole with the purpose of creating a visual representation of black hole jets. Black holes are areas of small radii of extremely high concentrations of mass. The strong gravitational pull created by the concentrated mass in the small volume of space pulls in plasma and gas from surrounding stars and celestial objects. This gas and plasma creates flat disks that revolve around the black hole. As the space material approaches the black hole it may encounter the ergosphere, an egg-shaped region of distorted space around the center of the black hole. There, the space material is ejected through these jets when it gains energy from the rotating motion of the core of the spinning black hole. If the material reaches the event horizon, however, it is sucked into the opening of the black hole. These powerful jets are the universe's recycling method. They contain electrons as well as heavy atoms such as iron and nickel. When shot away from the center of the black hole at two-thirds the speed of light, black hole jets have the potential to dictate when and how new nearby galaxies form.
