One final important point to make about working with the Moon, is that it helps to realise that all things have the need for both generating and clearing. This means that both aspects of the lunar cycle can be used to your advantage for any particular issue or project. For example, if you are looking at having a huge clean-up at home, you could plan and design everything, including any furniture/room arrangement changes, during the waxing time. This is your time for creating new looks and new ways to live. You could then go on to do the cleaning up work during the Waning period. The perfect time to let go of the old, so that the new designs can take their place. The astronomers then conducted an analysis called a Bouger correction in order to subtract the gravitational effect of topological features, such as valleys and mountains, from the total gravity field. What is then left is the gravity field hidden beneath the lunar surface, existing within its crust. Therefore, the results of the new study support the idea that primitive life could potentially have evolved on Ganymede. This is because places where water and rock interact are important for the development of life. For example, some theories suggest that life arose on our planet within hot, bubbling seafloor vents. Before the new study, Ganymede's rocky seafloor was believed to be coated with ice--not liquid. This would have presented a problem for the evolution of living tidbits. The "Dagwood sandwich" findings, however, indicate something else entirely--the first layer on top of Ganymede's rocky core might be made up of precious, life-sustaining salty water.
