More images of Enceladus are released by NASA

NASA  has released new images of Saturn's icy moon Enceladus (pronounced [en-SELL-ah-dus] )
 that were taken by the Cassini spacecraft in November.You can view these images by going to the following website:

Image: This image shows the south polar region of Saturn's moon Enceladus.

This  image and all of the images released today by NASA were taken by the Composite Infrared Spectrometer Imaging Science Subsystem which was built into the Cassini spacecraftThe image focuses on Baghdad Sulcus, a fracture in the south polar region.

"Enceladus is the sixth-largest moon of Saturn. It was discovered in 1789 by William Herschel.Enceladus is named after the Giant Enceladus of Greek mythology. The name Enceladus — like the names of each of the first seven satellites of Saturn to be discovered — was suggested by William Herschel's son John Herschel in his 1847 publication Results of Astronomical Observations made at the Cape of Good Hope.  He chose these names because Saturn, known in Greek mythology as Cronus, was the leader of the Titans."


"Enceladus  was discovered by Fredrick William Herschel on August 28, 1789, during the first use of his new 1.2 m telescope, then the largest in the world.  Herschel first observed Enceladus in 1787, but in his smaller, 16.5 cm telescope, the moon was not recognized.  Due to Enceladus's faint apparent magnitude (+11.7m) and its proximity to much brighter Saturn and its rings, Enceladus is difficult to observe from Earth, requiring a telescope with a mirror of 15–30 cm in diameter, depending on atmospherical conditions and light pollution."

"Enceladus orbits Saturn at a distance of 238,000 km from the planet's center and 180,000 km from its cloudtops, between the orbits of Mimas and Tethys, requiring 32.9 hours to revolve once (fast enough for its motion to be observed over a single night of observation)."

"Enceladus is a relatively small satellite, with a mean diameter of 505 km, only one-seventh the diameter of Earth's own Moon. It is small enough to fit within the length of the United Kingdom; in fact, it is barely the size of England alone."  (source:http://en.wikipedia.org/wiki/Enceladus_%28moon%29)

Thoughts worth thinking about

"Our subconscious minds have no sense of humor, play no jokes and cannot tell the difference between reality and an imagined thought or image. What we continually think about eventually will manifest in our lives."-Sidney Madwed



Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia



A person's true wealth is the good he or she does in the world. - Mohammed



Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. -Albert Einstein



The best way to find yourself, is to lose yourself in the service of others. - Ghandi



The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller



Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns



Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures. -His Holiness The Dalai Lama



Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -



Milan Kundera, The Unbearable Lightness of Being



The worst sin towards our fellow creatures is not to hate them, but to be indifferent to them. That's the essence of inhumanity. -George Bernard Shaw

Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165

The hostile attitude of conquering nature ignores the basic interdependence of all things and events---that the world beyond the skin is actually an extension of our own bodies---and will end in destroying the very environment from which we emerge and upon which our whole life depends.
