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.
