But why that bulge is there has been a mystery, … Now, a group of international scientists have found that perhaps the tidal processes of Jupiter’s icy moon, Europa, can provide a clue. “Europa is a completely different satellite from our moon, but it gave us the idea to look at the process of tidal flexing of the crust over a liquid ocean,” said Ian Garrick-Bethell, the lead author of a new paper that offers an explanation for the lop-sided Moon.  

Aboriginal time runs east to west

Source:   Bruce Bower, Science News Excerpt: Sun’s trajectory may channel time’s flow for one remote group. …Time rises in the east and sets in the west in a remote part of Australia. Aborigines living there assume that time moves westward, apparently in accord with the sun’s daily arc across the sky, say Stanford University psychologist Lera Boroditsky and linguist Alice Gaby of the University of California, Berkeley. ...For them, time flows from left to right when facing south, from right to left when facing north, toward the body when facing east and away from the body when facing west....

Source:   NASA Excerpt: Our world's birth story is intertwined with that of its family -- the Earth formed along with the rest of our solar system, 4.5 billion years ago. ... New scientific models and data suggest that Jupiter, Saturn, Uranus, and Neptune shifted places early in our solar system's history. YSS missions will help scientists piece together this dramatic history!
