European astronomers have taken a stunning photo of a Big Brother-style cosmic eye, nicknamed the Eye of God, staring down from space.
The bright blue pupil and the white of the eye are fringed by flesh-colored eyelids - but this eye is so big that it light takes two and a half years to cross from one side to the other.
The object is actually a shell of gas and dust that has been blown off by a faint central star. Our own solar system will meet a similar fate five billion years in the future.
It lies around 700 light-years away in the constellation of Aquarius, and can be dimly seen in small backyard telescopes by amateur astronomers who call it the Helix nebula. It covers an area of sky around a quarter the size of the full moon.
The photo was taken with a giant telescope at the European Southern Observatory, high on a mountain top at La Silla in Chile. It is so detailed that a close-up reveals distant galaxies within the central eyeball.
