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 Moon in the Birth Chart. The Moon is a very important planet in the Birth Chart as it is from this that we operate from through childhood and thus it becomes our foundation. Although we grow towards our Sun (our own 'mind') in adulthood, the Moon is a 'feeling, reflective' energy that picks up and stores early messages and experiences. Many of our behavioural and emotional problems can be uncovered by examining the role of Moon in the Natal Chart. The Moon informs and represents the way we habitually respond and react throughout life. It denotes our instinctive behaviour and the sign it is in describes its innate quality, whereas the house reflects the environmental influence. Any aspect to the Moon shows how it reacts. If for example it has a connection to Mars, then it may be more assertive in having its needs met. Moon with Venus will emphasise its female or creative quality and Moon in aspect to Mercury may be able to express its feeling in some communicative way..
Earth's Moon is the largest and brightest object suspended in the darkness of the starry night sky. It is both lovely and enchanting, and it has, since ancient times, inspired curiosity and wonder in human beings who gaze up at the mysterious sky after the Sun has set. As such, Earth's Moon has long served as the inspiration for imaginative, wild and marvelous tales--it is the stuff of mythology and folklore. The "Man in the Moon" refers to several fantastic images of a human face that certain traditions see outlined in the gleaming disk of the full Moon. In November 2013, astronomers using data from the lunar-orbiting twins composing NASA's Gravity Recovery and Interior Laboratory (GRAIL) mission, announced that they have been acquiring new and fascinating insight into how this bewitching "face," etched on our Moon's disk, received its captivating and enchanting good looks!
