Planetary nebula Abell 30
11/18/12

 

The intricate pattern of planetary nebula Abell 30 is revealed in these images that combine optical Hubble Space Telescope (HST) images with XMM-Newton and Chandra X-ray data. In the main image a large spherical shell is seen in emission of hydrogen (blue) and oxygen (red) as the result of the star’s outer shell being stripped off by a dense wind and expanding outward over the last 12 500 years. The inset panel zooms in to the heart of the planetary nebula to reveal intricate details closer to the star. The tail-like structures (orange) mark the dense knots of material from the ‘born-again’ event. Credit: Main image: X-ray: ESA/XMM-Newton; optical: NSF/NOAO/KPNO; inset: NASA/CXC/IAA-CSIC/M. Guerrero et al; optical: NASA/STScI
