Interesting facts about space.

There have been prominent philosophers, artists, poets, scientists and other scholars in the moon. They have contributed a wealth of benefits to the moon community by spreading their knowledge and ideas. The old generations have kept the harmony of the moon community intact. The elders in the moon at present have been somewhat perturbed in the recent past with the present generation of children, who seek to express their reasoning as to how they wish to move forward into the future. The elders have observed trends of some individuals tending to deviate from the traditional social system and attempting to adopt different living styles. But up to now the elders have been able to address such situations and have managed to keep the traditional systems intact.



and here is another

For this reason, for many years astronomers considered the possibility that hydrocarbon lakes and seas might exist on this fantastic moon-world. Data that finally arrived courtesy of the joint NASA and European Space Agency's (ESA's) Cassini-Huygens mission lived up to their expectations. Since arriving at the Saturn system in 2004, the Cassini spacecraft has revealed more than 620,000 square miles of Titan's long-hidden, bewildering surface--and it has shown that almost two percent of Titan's entire surface is covered in liquid.



and finally

Titan circles its giant parent-planet once every 15 days and 22 hours. Like Earth's own large Moon, and a number of other moons dancing around the quartet of giant gaseous planets of our Solar System's outer realm, its rotation period is identical to its orbital period. This means that Titan is tidally locked in synchronous rotation with Saturn--always showing only one face to its planet.

The exact composition of these bodies of liquid remained unknown until 2014, when the radar instrument aboard Cassini was first used to show that Ligeia Mare, the second largest sea on Titan, is richly endowed with methane. Ligeia Mare is similar in size to two of the Great Lakes on Earth combined--Lake Huron and Lake Michigan! The new study, published in the February 25, 2016 issue of the Journal of Geophysical Research: Planets, which used the radar instrument in a different mode, independently confirmed the 2014 result. "It's a marvelous feat of exploration that we're doing extraterrestrial oceanography on an alien moon," commented Dr. Steve Wall in an April 26, 2016 Jet Propulsion Laboratory (JPL) Press Release. Dr. Wall, who is of the JPL in Pasadena, California, is Cassini radar team deputy lead.



However, the new findings also mean that scientists must come up with other explanations for why Earth's Moon is depleted of potassium, sodium, and other volatile elements. Additional explanations for this exist. One possible alternative explanation is that the volatile elements contained within the disk showered down onto the proto-Earth instead of escaping, or being part of lunar formation. Another explanation is that these volatile elements were part of our Moon when it first accreted from the post-collision disk but were later lost.



Astronomers have for years contemplated two competing hypotheses explaining the origin of the Martian moons. The first proposes that Phobos and Deimos are, indeed, escapees from the Main Asteroid Belt. Alas, this viewpoint begs the question of why they should have been so cruelly captured by their adopted parent-planet in the first place. An alternative theory points to the possibility that the moons were born from the debris left by a violent collision between Mars and a primordial protoplanet--a baby planet still under construction. However, this theory also suffers from uncertainty because it does not explain precisely how this particular tragic mechanism gave rise to Phobos and Deimos.
