>MyCn18, a young planetary nebula located about 8,000 light-years away, was imaged with the Wide Field and Planetary Camera 2 aboard Hubble. This image reveals the true shape of MyCn18 to be an hourglass with an intricate pattern of "etchings" in its walls. This picture has been composed from three separate images taken in the light of ionized nitrogen (represented by red), hydrogen (green), and doubly ionized oxygen (blue). Photo courtesy of NASA/ESA
