In report will occupy new network on July 10 Singapore " associated morning paper " report, royal astronomy can weigh England recently, be in from the earth the place of 2000 much light-year, center of a galaxy exceeds great quality black hole to happen " dyspeptic " , hitting " full belch " space of Xiang Xing time is ejective one pile material.

The report says, multilateral astronomer is many more integrated the observation data traverse of wave band binoculars this one phenomenon. This galaxy number is NGC5195, it has a bigger companion NGC5194, both manacle together by gravitation. Before this already observation has arc of two X ray near them, according to saying this is black hole of NGC5195 galaxy center " belch " those who form.

Royal astronomy meets England to released news bulletin to say recently, by England Mancunian old course learns a group of a leader, use the high definition picture that array of British E-MERLIN radio telescope takes, the observation result of the equipment such as ray of X of the haing suddenly binoculars that combines the United States, Qian Dela and binoculars of very big array, studied a black hole " belch " erupt corporeal detail.

Xing time, among them the electron travels with approaching velocity of light, with the gas of interstellar space and dust interaction, give out radio wave. Bow wave immediately makes like froth bubble gas and dust heat expand, give out X ray, and from hydric on come off the electron forms ionic hydrogen, produce the arc that the observation before this goes to.
