NASA: ‘X’-ploring the Eagle Nebula and ‘Pillars of Creation’(’X射线’-探索巨蛇座鹰状星云和"创造之柱")
This new composite image shows the region around the Pillars, which are about 5,700 light years from Earth. The image combines X-ray data from NASA’s Chandra X-ray Observatory and Hubble Space Telescope optical data. The optical image, taken with filters to emphasize the interstellar gas and dust, shows dusty brown nebula immersed in a blue-green haze, and a few stars that appear as pink dots in the image. The Chandra data reveal X-rays from hot outer atmospheres from stars. In this image, low, medium, and high-energy X-rays detected by Chandra have been colored red, green, and blue.
