The vista was created using 48 images taken by Hubble's now-defunct Advanced Camera for Surveys (ACS) during March and July 2005. The ACS captured the glow of hydrogen gas, but the imagery was colored with observations from Cerro-Tololo Interamerican Observatory's 4-meter telescope in Chile. The colors in the image correspond to emission from sulfur (red), hydrogen (green), and oxygen (blue).

According to the Space Telescope Science Institute, Hubble has orbited Earth 100,000 times, for a total of 3.8 billion kilometers (2.4 billion miles), and has taken nearly 500,000 images.
