QUOTE Only three solar twins were previously known: 18 Scorpius, HD 98618, and HIP 100963. But while they were all like the Sun in many ways, there was one major difference: the amount of lithium they contained. They all had several times more than the Sun. Astronomers wondered if the Sun was unique in its low amount of lithium. The discovery of this new solar twin puts that question to rest: it has the same low lithium content as the Sun. The study turned up another solar twin, HIP 73815, that contains a similarly low amount of lithium. http://mcdonaldobservatory.org/news/releases/2007/1109.html -------------------- "I got a call from NASA Headquarters wanting a color picture of Venus.
