    Blinking Nebula (NGC 6826)

    Blinking Nebula, NGC 6826
    A planetary nebula in the constellation Cygnus whose nickname stems from the fact that, when looked at directly through a small telescope, it seems to disappear, leaving only the central star – one of the brightest of any planetary – still in view. Using averted vision, the nebula winks back into view. NGC 6826's eye-like appearance is notable for its prominent red FLIERs. The image shown here was taken with the Hubble Space Telescope.
