A rock fragment containing a previously unidentified natural quasicrystal may be the remnant of a meteorite that originated in the early solar system more than 4.5 billion years ago before Earth even existed. Until now, researchers had assumed such quasicrystals, whose atoms are arranged in a quasi-regular pattern rather than the regular arrangement of atoms inside a crystal, were not feasible in nature. In fact, until now the only known quasicrystals were synthetic, formed in a laboratory under carefully controlled conditions. (This year's Nobel Prize in chemistry honored Dan Shechtman for his 1982 discovery of quasicrystals, which at the time were thought to break the laws of nature.) "Many thought it had to be that way, because they thought quasicrystals are too delicate, too prone to crystallization, to form naturally," researcher Paul Steinhardt of Princeton University said. The new finding, described this week in the journal Proceedings of the National Academy of Sciences, suggests "quasicrystals are much more common in the universe than we thought," Steinhardt added
