SPACE-HUBBLE GEODE
In this unusual image obtained 22 August, 2004, the NASA/ESA Hubble Space Telescope captures a rare view of the celestial equivalent of a geode - a gas cavity carved by the stellar wind and intense ultraviolet radiation from a young hot star. Real geodes are handball-sized, hollow rocks that start out as bubbles in volcanic or sedimentary rock. Only when these inconspicuous round rocks are split in half by a geologist, do we get a chance to appreciate the inside of the rock cavity that is lined with crystals. In the case of Hubble-s 35 light-year diameter -celestial geode- the transparency of its bubble-like cavity of interstellar gas and dust reveals the treasures of its interior. AFP PHOTO/ESA/NASA
