This image provided by the Hubble Space Telescope shows the striking details of the famed planetary nebula designated NGC 2818, which lies in the southern constellation of Pyxis (the Compass). The spectacular structure of the planetary nebula contains the outer layers of a star that were expelled into interstellar space. The glowing gaseous shrouds in the nebula were shed by the central star after it ran out of fuel to sustain the nuclear reactions in its core. NGC 2818 is often heralded as one of the Galaxy’s few planetary nebulae to be discovered as a member of an open star cluster.
