IC 3568 glows like a plasma globe in this image from NASA's Hubble Space Telescope. IC 3568 is a young planetary nebula having has a diameter of only about 0.4 light-years or about 800 times the size of our solar system. This means that it would take light less than a six months to cross the nebula.

Faint structure, like the inside of a lemon, can be seen in the bright central bubble surrounding the central star. A faint halo extends beyond the bright center in this classic “round” planetary nebula.
