The star HD 44179 is surrounded by an extraordinary structure known as the Red Rectangle. It acquired its moniker because of its shape and its obvious color when seen in early images from soil. This strikingly detailed Hubble image reveals how,when seen from space, the nebula, and rather than being rectangular,is shaped like an X with additional complex structures of spaced lines of glowing gas, a little like the rungs of a ladder.
