The Big Red Eye | What makes this cosmic eye look so red? Dust. The featured image from the robotic Spitzer Space Telescope shows infrared light from the well-studiedHelix Nebula (NGC 7293) a mere 700 light-years away in the constellation of the Water Carrier Aquarius. The two light-year diameter shroud of dust and gas around a central white dwarf has long been considered an excellent example of a planetary nebula
Nebula IC 405 aka the Flaming Star Nebula surrounds star AE Aurigae, lies about 1,500 light years distant, spans about 5 light years, and is visible with a small telescope toward the constellation of the Charioteer (Auriga) (Credit: Martin Pugh)
The Horsehead Nebula is a cloud of ionized-hydrogen in the constellation Orion. These clouds are lit from within by young, hot stars. The interstellar dust absorbs the light from part of the ionized cloud creating this beautiful contrast. Image Credit: NA
