Pan-STARRS and Nebulae
A single field from the world's most powerful survey instrument captures this spectacular skyview. Looking toward Sagittarius, the scene spans nearly 3 degrees or six times the width of the Full Moon. At bottom, upper right, and lower left it covers the Lagoon Nebula (M8), the Trifid Nebula (M20), and NGC 6559 , in the crowded, dusty starfields of the central Milky Way . The adopted color scheme shows dust reddened starlight in red hues and normally red emission from hydrogen atoms in green. Built and operated by the Pan-STARRS project, the instrument features a 1.4 gigapixel (billion pixel) digital camera and telescope. Pan-STARRS, the Panoramic Survey Telescope & Rapid Response System, is intended to scan the skies for potentially dangerous near-earth asteroids and comets , exploring the Universe with a unique high resolution, wide field view .
