Astronomical Seal Observatory images Fox Fire Nebula
The Abu Dhabi Astronomical Observatory successfully captured a detailed image of the "Fox Fire Nebula," a planetary nebula located approximately 2,770 light-years from Earth. The nebula features a bright gaseous arc resembling the logo of the web browser "Firefox." The nebula displays an asymmetrical structure resulting from the movement and high velocity of its central star, which reaches about 125 kilometers per second. This has led to the formation of a luminous arc and a gaseous tail extending roughly 15 arcminutes, estimated to be around 22,000 years old. The photo was taken using a 14-inch telescope, employing narrowband filters to reveal emissions from hydrogen, oxygen, and sulfur, thereby highlighting the distribution of these elements and the nebula's intricate structure.
