Astronomers studying the "jet stream" age in two million years

Two million light-years from the center of a distant galaxy trail make bigger, surprisingly suggestive of a jet stream that reserve military fighter jet engine only in this case is a black hole, and the substance of the jet is moving at a speed close to the speed of light.

The new image of the jet which has been studied previously designated as PKS 0637-752, showing alternating light and dark areas on it, similar to the phenomenon in jet fighter jets, called "diamond condensation".

A team of scientists led by Dr. Leif Godfrey from the Department Kertinskogo University International Radio Astronomy Centre recently conducted study PKS 0637-752. Astronomers say that such jets occur when the matter in the galaxy falls into a black hole, but much in the origin of these phenomena is still a mystery to them. However, researchers believe that if the appearance of the light areas in the astronomical jet caused by the same processes as the appearance of diamonds in the thickening of the earth fighter jet stream, it could give scientists important information about the strength of the jet and the space density of the surrounding space.

A new study on PKS 0637-752, appeared in the journal The Astrophysical Journal Letters.
