. We are looking down a tunnel of gas cast off by a dying star thousands of years ago. Look for elongated dark clumps of material embedded in the gas at the edge of the nebula, and also for the dying central star floating in a blue haze of hot gas. The colors represent three different chemical elements: helium (blue), oxygen (green), and nitrogen (red). AURA / STScI / NASA
