A Reborn Planetary Nebula

These pictures of the planetary nebula Abell 30, (a.k.a. A30), show among the clearest views ever before gotten of an unique phase of advancement for these objects. The inset image on the right is a close-up view of A30 showing X-ray data from NASA's Chandra X-ray Observatory in purple and Hubble Space Telescope (HST) data showing optical emission from oxygen ions in orange. Left wing is a larger view showing optical and X-ray data from the Kitt Peak National Observatory and ESA's XMM-Newton, respectively. In this image the optical data show emission from oxygen (orange) and hydrogen (green and blue), and X-ray emission is colored purple. A planetary nebula-- so called because it appears like a planet when seen with a little telescope-- is formed in the late phase of the advancement of a sun-like star.
