NGC 1579: Trifid of the North Don GoldmanColorful NGC 1579resembles the better knownTrifid Nebula, but lies much farther north in planetEarth’s sky, in the heroic constellationPerseus.About 2,100 light-years away and 3 light-years across,NGC 1579 is, like the Trifid,a study in contrasting blue and red colors, with dark dust lanesprominent in the nebula’s central regions.In both regions, dust reflects starlight to producebeautiful blue reflection nebulae.But unlike the Trifid,in NGC 1579the reddish glow isnot emission from clouds of glowing hydrogengas excited by ultraviolet light from a nearby hot star.Instead, the dust in NGC 1579 drastically diminishes, reddens, andscatters the light from an embedded,extremely young,massive star, itself is strong emitter of the characteristic redhydrogen alpha light.amazed%7Cutmcsr%3Dhttp%3A%2F%2Fantwrp%2Egsfc%2Enasa%2Egov%2Fapod%2Fastropix%2Ehtml%7Cutmcmd%3Drss%3B%2B)
