Interesting thoughts!

Each of the little Space eggs resides within its own ring arc--which is a fragmentary ring of Saturn. One hypothesis states that glittering ice crystals swarming around in the ring arc might be floating down to the surface of Methone, filling in its impact craters or other rough topography. This is something that is thought to have occurred on two other small, icy moons of Saturn--Atlas and Pan. Icy stuff swarming around in Saturn's rings apparently piled up around each moonlet's equator.



Earth's Moon Reveals An Ancient Secret. Many astronomers think that during an ancient era, termed the Late Heavy Bombardment, our young Moon was violently battered by a marauding multitude of invading asteroids that crashed onto its newly formed surface. This attack of pelting objects from space occurred about 4 billion years ago, and the shower of crashing asteroids excavated impact craters, and also slashed open deep fissures, in the lunar crust. This sustained shower of merciless impacts increased lunar porosity, and opened up an intertwining network of large seams under the Moon's surface.



Aside from the monthly phases of the moon, there is also a daily lunar effect on fish feeding habits. Moonrise and moonset appear to be very good times to go fishing, if other factors like the weather are cooperative. Studies show that fish are more active 90 minutes before and after either the moonrise or moonset. Given this, you now know when is a good time to go fishing, provided it fits your schedule!

Titan orbits Saturn once every 15 days and 22 hours. Like Earth's large Moon, in addition to many other moons in our Solar System, Titan's rotational period is precisely the same as its orbital period. This means that Titan only shows one face to its parent-planet, while the other face is always turned away.



Conventionalized images of the Man in the Moon seen in Western art usually display a simple "face" in the full Moon, or a human profile in the crescent Moon, that correspond to real topological features on the lunar surface.



Until 2004, no spacecraft had visited Saturn for more than twenty years. Pioneer 11 had snapped the very first up close and personal images of Saturn when it traveled past it in 1979, Voyager 1 flew past Saturn about a year later, and in August 1981, Voyager 2 had its own fleeting but very productive close encounter. At last, on July 1, 2004, NASA's Cassini spacecraft went into orbit around Saturn, and started taking very revealing photographs of this bewitching planet and its many lovely and bizarre moons.
