Here, NASA’s Spitzer Space Telescope turns its infrared array camera onto the Ring Nebula, which appears to be surrounded by intricate flower petals nestled in its outer shell. Its namesake ring is formed by a thick cylinder of gas and dust encircling the core star. The nebula sits about 2,000 light-years from Earth in the constellation Lyra. One light-year is about 5.88 trillion miles (9.64 trillion kilometers). The image was released on February 11, 2005. This image was featured as our Image of the Day |
