If you watch the video, apparently this 90 million degree plasma has very specific spectral peaks that are related to Nickel and Iron. Now of course since the mainstream remains in pure denial of the role of electricity in space, they're lamely attempting to 'explain' these high temperature plasmas as being directly heated by the "black hole" in the core of the galaxy. Of course that "explanation" isn't working very well:Before its demise, though, Hitomi was able to peer into the Perseus cluster of galaxies, an assemblage of thousands of galaxies bound together by gravity. Located about 240 million light-years away and named for its host constellation, the Perseus galaxy cluster contains a vast amount of extremely hot gas. At temperatures averaging 90 million degrees Fahrenheit (50 million degrees Celsius), the gas glows brightly in X-rays. Prior to Hitomi's launch, astronomers lacked the capability to measure the detailed dynamics of this gas, particularly its relationship to bubbles of gas expelled by an active supermassive black hole in the cluster's core galaxy, NGC 1275.
"For the first time, we have mapped the motion of the X-ray-emitting gas in a cluster of galaxies and determined its velocity structure over a wide range of spatial scales," said Goddard's Richard Kelley, the U.S. principal investigator for the Hitomi collaboration. "Although this gas is continually stirred by fast outflows from the central black hole, its velocities are small on astronomical scales and show evidence for only minor levels of turbulence."
Translation: The plasma is moving way too slow to be explained by bow shock heating from the black hole."I'm surprised the hot gas is absorbing the power output of the black hole so quickly, so efficiently. The gas is relatively stable and isn't getting pushed around as much as we thought," said team member Brian McNamara, a professor of physics and astronomy at the University of Waterloo in Ontario. "Hitomi's Perseus observation tells us that we can probably weigh distant galaxy clusters to greater accuracy than we can weigh our own Milky Way galaxy."
It's too bad this mission broke apart before it had a chance to return more data, and of course it's too bad that the mainstream *refuses* to use the correct scientific term for 'plasma'.
All I can say, is "90 million degrees??????" That's a whole lot of current running through the galaxy and the voltage must be enormous.
