Determining age of the ‘Methuselah Star’

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 - Astronomers are a step closer to timing the birth of the oldest known star with a well-determined age. This "Methuselah Star" could be as old as 14.5 billion years, which is a dilemma considering the calculated age of the Universe is only 13.8 billion years. See article.
g Abodes - A new analysis of data shows that molten rock may have been present on the Moon more recently and for longer periods than previously thought. Differentiation — a settling out of rock layers as liquid rock cools — would require thousands of years and a fluid rock sea at least six miles deep. See article.
g Message - Could humans be the only intelligent beings in all the vastness of the universe? Or are we just one humble race, a member of a vast intergalactic fraternity of advanced civilizations? SETI, the Search for Extraterrestrial Intelligence, is the scientific quest to answer these great unknowns. See article.
