Chandra X-ray Image of NGC 5315
NGC 5315, a planetary nebula that lies in the southern constellation Circinus, has a Wolf-Rayet-type central star. There are only about 50 Wolf-Rayet-star planetary nebulas known in the entire sky. Wolf-Rayet-type stars are a special class of hot, hydrogen-deficient stars that display particularly massive and energetic stellar winds.

Hubble Optical Image of NGC 5315
Planetary nebula NGC 5315 reveals an x-shaped structure in optical light. This shape suggests that the star ejected material in two different outbursts in two distinct directions. Each outburst unleashed a pair of diametrically opposed outflows. The image was taken with Hubble's Wide Field Planetary Camera 2 in February 2007.
