The celestial eye of the planetary nebula NGC 3918 seen by Hubble
A new image captured by the Hubble Space Telescope shows the planetary nebula NGC 3918, nicknamed the “Blue Planetary” or “The Southerner”. Its shape in some ways reminds of an eye with special colors and seeing it is a lucky event because it will not last long in astronomical terms since this phase will end within a few tenth of millennia.
