Is this licence acceptable?

My mods europa_moon and io_moon have the same skybox. The skybox has an image of Jupiter taken from https://www.flickr.com/photos/nasahubble/46616136772 , and there it is licenced as CC-BY-2.0. I found this image by using Google images and the tool "Labeled for reuse"/"Labeled for reuse with modification". Is this licence acceptable, or should I find another Jupiter image?
