Giant Green 'Spider' Invades Stellar Nursery in Eerie New Image

The image, which NASA released Thursday (April 14), shows the Spider Nebula, a giant cloud of gas and dust that lies about 10,000 light-years from Earth, in the constellation Auriga. "In the image, infrared wavelengths, which are invisible to the unaided eye, have been assigned visible colors," NASA officials wrote in an image description. "Toward the right of center, against the black background of space, you can see a bright group of stars called 'Stock 8,'" NASA officials wrote.
