Space.com is featuring an article about new discoveries regarding Earth's closest star. By examining other sun-like stars with the Chandra X-ray telescope, scientists have found them to contain three times as much neon as is observed in the Sun with different techniques. The implication is that these previous techniques (and therefore all the other observations that rely on them, about any star in the universe) don't actually work, or there's something very very strange about the Sun. Chandra can't be used on the Sun because it's too close... the sensors would burn out.
