IC 4406: A Seemingly Square Nebula

NASA APOD
COSMIC MESSAGE

How can a round star make a square nebula? This conundrum comes to light when studying planetary nebulae like IC 4406. Evidence indicates that IC 4406 is likely a hollow cylinder, with its square appearance the result of our vantage point in viewing the cylinder from the side. This image is a composite made by combining images taken by the Hubble Space Telescope.
