The giant elliptical galaxy NGC 4261 is one of the twelve brightest galaxies in the Virgo cluster, located 45 million light-years away. A giant disk of cold gas and dust fuels a possible black hole at the core of the galaxy. Estimated to be 300 light-years across, the disk provides astronomers with a clear view of the bright hub, which presumably harbors the black hole. The dark, dusty ring of the hub is a cold outer region which extends inwards to an ultra-hot area a few hundred million miles from the suspected black hole. This area of dense stars feeds matter into the black hole, where gravity compresses and heats the material.
Hot gas rushes from the vicinity of the black hole creating the radio jets.
The jets are aligned perpendicular to the disk, like an axel through a wheel. The following information. A good theory explaining gravity remains one of the biggest mysteries in physics today. Because we don't really understand how gravity works, nobody knows what happens inside the biggest sources of gravity in the universe, black holes. Israel feels that a quantum theory of gravity is needed to explain what happens to things that fall into black holes.
