Summary
NASA image of M57, the Ring Nebula, taken from English Wikipedia.
Image Credit: NASA and The Hubble Heritage Team (STScI/AURA)
Object: Planetary nebula M57, the Ring Nebula, in Lyra constellation
Image info: The color image was assembled from three black-and-white photos taken through different colour filters with the Hubble telescope's Wide Field Planetary Camera 2
Details:
- Blue isolates emission from very hot helium, which is located primarily close to the hot central star.
- Green represents ionized oxygen, which is located farther from the star.
- Red shows ionized nitrogen, which is radiated from the coolest gas, located farthest from the star.
The gradations of colour illustrate how the gas glows because it is bathed in ultraviolet radiation from the remnant central star (hot white dwarf), whose surface temperature is a white-hot 120,000 degrees Celsius/
