Located 1,500 light-years from Earth, the Orion nebula is the brightest spot in the sword of the constellation Orion. Both NASA's Spitzer and Hubble space telescopes contributed to this vibrant image. Four massive stars, collectively called the Trapezium, appear as a yellow smudge near the image center. Visible and ultraviolet data from Hubble appear as swirls of green that indicate the presence of gas heated by intense ultraviolet radiation from the Trapezium's stars. Less-embedded stars appear as specks of green, and foreground stars as blue spots. Meanwhile, Spitzer's infrared view exposes carbon-rich molecules called polycyclic aromatic hydrocarbons, shown here as wisps of red and orange. Orange-yellow dots are infant stars deeply embedded in cocoons of dust and gas.
