Observations of a supermassive back holes



Two papers about the astronomy were published in the May 10, 2012 issue of The Astrophysical Journal and in the October 20, 2012 issue of The Astrophysical Journal.

According the two papers, there is a supermassive black hole at the center of the galaxy which is located some 850 million light years from Earth.

The researchers caught the the radio emission comeing from two jets of particles that are speeding at millions of miles per hour away from the black hole.It is estimated that mass of the black hole is about 100 million times the mass of our Sun.

The bright X-rays which can be observed by the Hubble Space Telescope in the center of the image mark a pool of million-degree gas around the black hole. The optical light that can be seen is from the stars in the galaxy.

The Observer can come with it from images and data that most of the low-energy X-rays from the vicinity of the black hole are absorbed by dust and gas, probably in the shape of a giant doughnut around the black hole. This doughnut, or torus blocks all the optical light produced near the black hole, so astronomers refer to this type of source as a hidden or buried black hole.
