Fifth planet found orbiting 55 Cancri and the star of Bethlehem

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here's today's news:
g Abodes - Astronomers have discovered a fifth planet circling the star 55 Cancri – a record number of confirmed planets for a star beyond our Solar System. The new planet is probably similar to Saturn, except that it rests within the 'habitable zone' of its parent star. See article. Note: This article is from 2007.
g Life - If there is life on Jupiter’s moon Europa, what would it be like? The answer partly depends on the type of ocean water that is under the moon's icy outer shell. See article. Note: This article is from 2007.
g Message - Here’s an article in which Dave DeBoer, project engineer for the Allen Telescope Array, discusses what the unique telescope will offer. The development of the Allen Telescope Array is marked by many innovations crafted with the express purpose of building a world-class state-of-the-art astronomical facility at a fraction of the price of existing radio telescopes. See article. Note: This article is from 2003.
g Learning - Although the beginning of the Christian Era is long believed to have been marked by the appearance of the Star of Bethlehem, debate has raged for centuries about what caused the landmark to appear in the skies. See article.
