Determining the Age of 'Methuselah', the Oldest Known Star
|
| Topic: Cosmic Evolution |
03/18/13 |
| Summary:
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. |

| Summary:
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. |
