The recent discovery of a star with spiral arms startled researchers using the Subaru telescope in Hawaii. The star, SAO 206462, is more than four hundred light years from Earth in the constellation Lupus, the wolf. Two spiral arms, acquired by the Subaru Telescope and its HiCIAO instrument, emerge from the gas-rich disk around SAO 206462. This image is the first to show spiral arms in a circumstellar disk --some 14 billion miles across, or about twice the size of Pluto's orbit in our own solar system.
