This NASA Hubble Space Telescope (HST) image reveals a pair of one-half light-year long interstellar twisters, eerie funnels and twisted-rope structures in the heart of the Lagoon Nebula (Messier 8) which lies 5,000 light-years away in the direction of the constellation Sagittarius. The central hot star, O Herschel 36 (lower right), is the primary source of the ionizing radiation for the brightest region in the nebula, called the Hourglass. Buy this as a superb wall poster, a canvas print or a framed print.
