Ganymede: Ganymede is both the largest moon of Jupiter, our Solar System's planetary behemoth, as well as the largest moon in our entire Solar system. Observations of Ganymede by the HST in 2015 suggested the existence of a subsurface saline ocean. This is because patterns in auroral belts and rocking of the magnetic field hinted at the presence of an ocean. It is estimated to be approximately 100 kilometers deep with a surface situated below a crust of 150 kilometers.
The astronomers observed this effect in the upper layer of the lunar crust, termed the megaregolith. This layer is heavily pockmarked by relatively small craters, measuring only 30 kilometers or less in diameter. In contrast, the deeper layers of lunar crust, that are scarred by larger craters, appear not to have been as badly battered, and are, therefore, less porous and fractured.
The New Moon. The New Moon is of more subtle nature. When this Moon touches the Sun she doesn't reflect any light. The New Moon is invisible to our eyes. The light of consciousness is gone for a short period of time and with it the self perception and self awareness. This moment signifies a clean slate, a new beginning into the next round of the Moon circling the Sun, the center of our universe representing the highest consciousness and life giving force for all the inhabitants of our earth.
