Wobble allows for Enceladus ocean and new space exploration vision becomes law

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:
g Stars - Violent galactic collisions have been invoked to explain surprisingly intense bouts of star formation occurring in ancient galaxies, but new evidence suggests a much gentler explanation. See article.
g Abodes - As Enceladus orbits Saturn, it wobbles slightly. This small but periodic shift might be enough to explain the liquid water ocean that scientists think may exist beneath the small moon's icy crust. See article.
g Cosmicus - President Obama signed a major NASA act on Oct. 11 that turns his vision for U.S. space exploration of asteroids and Mars into law. See article.
g Aftermath - Add one more worry to the computerized world of the 21st century. Could a signal from the stars broadcast by an alien intelligence also carry harmful information, in the spirit of a computer virus? Could star folk launch a "disinformation" campaign -- one that covers up aspects of their culture? Perhaps they might even mask the "real" intent of dispatching a message to other civilizations scattered throughout the Cosmos. See article. This article is from 2003.
