Nebula21Caldwell_C27 nebula.JPG Caldwell_C27 (NGC6888); 4700 light-years distant.
This nebula is located in the northern constellation Cygnus on the plane of the Milky Way galaxy. It represents the outer layers of gas stripped from the massive star HD 192163 (visible near the center of the object), as it turned into a red giant about 400’000 years ago. The gaseous envelope of 25x16 light-years dimension keeps expanding at a speed of up to 30,000 km/h. Due to its instability, the star has now entered a phase characterized by massive mass loss in the form of stellar gas which hits the slower expanding envelope at a speed of up to 4.5 million km/h. The shock front of this ejection induces the gaseous envelope to radiate at different wavelengths. Eventually, the star will end its life in a spectacular supernova explosion. Hydrogen is red, Oxygen is blue. | 75.75 kB | 07:49, 4 Dec 2011 | Aphrodite MacBain | Actions |

::: "It's difficult to explain"
::: He says and I see
I focused a bit more on the subtleties of bodily movement. This made for a quite different "feel". Trying to see intention, and then actually adjusting my posture as separate from that. It seems to me that when movement flows directly from intention, it feels natural, but usually there is something between it that makes it too slow or too fast. I haven't worked out what exactly that is yet.
I did manage to let straighten and let relax my legs simultaneously, something that had worked with my back and arms before, but not with my legs yet.

Musing too, on Eos's report: Alert Gentle Wild
Wild is confusing for the time being
maybe it is innocence?
