Planets Compared to Each Other

The fact is, the moon really does have a direct impact on the number of fish you catch and the size of those fish. The reason is that the gravitational pull of the moon on the earth affects the places and the timing of fish feeding patterns, and in fact almost every animal that is not a primate. Fish are particularly susceptible to the gravitational effects of the moon because of the differing heights of the tides. When you think about, the moon has a direct effect on the entire environment in which fish live! GRAIL has also generated new maps showing lunar crustal thickness. These maps have managed to uncover still more large impact basins on the near-side hemisphere of Earth's Moon--revealing that there are fewer such basins on the far-side, which is the side that is always turned away from Earth. This observation begs the question: How could this be if both hemispheres were on the receiving end of the same number of crashing, impacting, crater-excavating projectiles? According to GRAIL data, the answer to this riddle is that most of the volcanic eruptions on Earth's Moon occurred on its near-side hemisphere. HST's detection of a site, which appears to show persistent, intermittent plume activity on Europa, provides a promising target for the Europa mission to investigate. Equipped with its new and sophisticated suite of science instruments, the mission can detect whatever may potentially be swimming around in the hidden global ocean sloshing around beneath its secretive crust of ice.
