What is the difference between a Lunar Eclipse and New Moon? They seem quite similar and there is often confusion between the two. A lunar eclipse happens twice a year whereas a new moon happens once a month. Here is further clarification:
These icy moon-worlds are the next important step in the scientific quest for the Holy Grail of life beyond our own planet. It is a strange era in human history. Astronomers have collected large amounts of data revealing bewitching clues that habitable ocean moon-worlds may be out there, within the family of our very own Star. Humanity is poised at the beginning of a new era. Sophisticated new technology might very soon answer the profound, and very ancient question, "Are we alone?"
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.
