Submission + - The Milky Way's "Stellar Methuselah"

u-bend writes: "Discovery has an interesting little article about a super-ancient star right here in our galaxy. According to the article, the star could be almost as old as the universe itself.
From the article:
Known as HE1523-0901, the 13.2-billion-year-old star was born half a billion years after the universe exploded into existence, say astronomers.
That unprecedented birthdate was confirmed by using the European Southern Observatory's (ESO) Very Large Telescope to split the star's ultraviolet light into individual wavelengths — like a UV rainbow. In that rainbow, or spectrum, they were able to identify lines that show the presence of heavy elements like uranium and thorium."

"I've finally learned what `upward compatible' means. It means we get to keep all our old mistakes." -- Dennie van Tassel
