You're looking at the heart of your own galaxy with X-ray specs. This photograph was captured by NASA's Chandra X-Ray observatory, and shows the three massive star clusters that surround the supermassive black hole at the centre of the Milky Way. These star clusters have so many large, bright stars that the whole area blazes in the X-ray spectrum. This photo shows 1 million seconds of accumulated observing time by Chandra of these mysterious region of our galaxy.

Fraser, is it possible to re-link this one again?

In the center of the photo there is a curving yellow streak. Can anybody tell me what thats likely to be? Just arc of super heated gas, like when a super nova illuminates previously cast off material? Or is the scale too big?

In other wavelengths we've seen more detail of this streak as it extends into cirucular arcs. I don't recall more than speculation as to what they are (SNR, Jets curved by Strong Magnetic field, or something else) but they are going to tell an interesting story when we have the tools to study them in more detail.

This is not the one I was thinking it was, but this is actually a great extension of something I was definitely considering in the other one.
The one I was remembering was a much closer close up of Sag A and had four 'bright spots' numbered 1-4, very close to and showing the 'bright spot' of the massive black hole.

So, that one, and this one, talking about and showing the star clusters, coupled with this one below...

Which I now think that it is possible this doesn't just apply to Quasars...

Leads me to the very real possibility, that massive black holes are very likely star cluster making machines.
