About
The Blue Ring Nebula is thought to be the product of two stars merging into one. The collision of the bodies ejected a cloud of hot debris into space. A disk of gas orbiting the larger star cut the cloud in half, creating two cones that are moving away from the star in opposite directions. The base of one cone is moving almost directly toward Earth, while the other is moving almost directly away. Magenta represents optical light from the shockwave at the front of the expanding debris cones, outlining the two cone bases at their widest points. Blue represents far-ultraviolet light (not visible to the human eye) and comes from gas behind the shockwave. As the gas expands and cools, it forms hy — NASA JPL · 2020.
