I see a pair of bent blue knees, no cat women tho.
fastartceetoo, read the text again.
The star novaed inside of a cloud of cool difuse material, the nova shock wave is compressing that material into an irregularly spherical surface of visibly excited matter, thus the xrays. The pre-existing material is what is glowing as the nova's shock wave encounters it on its journey away from nova central. I am not sure if the shock wave is sweeping that material in front of it, along with it, or leaving some of it behind and now not glowing. If all of it is being swept along, then some of the original star that was blownoff prior to the nova event is at the front of the shock wave as well. The shock wave is where the material is glowing; basically the surface of the irregular sphere in the image is the location of the shock wave.
The nova remnent, the neutron star, is located near the center of the explosion, not the edge of the 'cloud'. (read text again)
The irregularity may be due to resistance of the preexisting material slowing the shock wave, or from irregularities in the explosions force within the star's interior. Polar regions seem to have more energetic forces, and I suspect that one of the stars poles was pointing at the area of the inset, with the most high xray activity. The opposite side of the sphere has a similar energetic area, but we do not see it well enough in the image to see it.
As stars have rotation and many convection currents within their body, any sudden collapse from gravity will retain all angular momentum components; this may have an effect upon the dispersion of energy in the nova explosion, and thus translate into the shape of the shock wave and material remnant cloud, like the crab nebula.
Thanks for asking, I hadn't said all this before and didn't know I knew it !
As for the 1000 km/sec velocity of the neutron star nova remnant; it is an artifact of an unballanced explosive force during the nova. It kicked the neutron star in its present direction. I would be interested to know that direction. Is it away from the inset area? Indicating the inset hot spot is the result of that unballaced explosion, and thusly no equal glowing area on the opposite side of the sphere, due to the opposite polar region having a likewise extra energetic energy, will be found.
