The painting above depicts a planetary nebula named NGC 2818. It is located about 10 000 light years away in the constellation Pyxis, that is in our galactic neighborhood. The gaseous clouds are the remnants of a central star that run out of fuel and collapsed. The colors of the original image indicate emissions from the nebula’s clouds, where red, green and blue designate nitrogen, hydrogen and oxygen respectively. As such, the image is again a false-color image, like almost all the HST’s depictions of nebulae. The vibrant colors often seen in science fiction movies, and in computer games, are misleading.
