Hen 1357: New Born Nebula
| Title |
Hen 1357: New Born Nebula |
| Explanation |
This Hubble Space Telescope [ http://oposite.stsci.edu/pubinfo/pr/1998/15/ ] snapshot shows Hen-1357, the youngest known planetary nebula [ http://antwrp.gsfc.nasa.gov/apod/ap011003.html ]. Graceful, gentle curves and symmetry suggest its popular name [ http://greeceny.com/ls/grade4/sea1.htm#Stingray ] - The Stingray Nebula [ http://oposite.stsci.edu/pubinfo/pr/1998/15/pr.html ]. Observations in the 1970s detected no nebular material, but this image from March 1996 clearly shows the Stingray's emerging bubbles and rings of shocked and ionized gas [ http://oposite.stsci.edu/pubinfo/pr/1998/15/ content/prc9815.txt ]. The gas is energized by the hot central star as it nears the end of its life, evolving toward a final white dwarf phase [ http://antwrp.gsfc.nasa.gov/apod/ap961203.html ]. The image also shows a companion star (at about 10 o'clock) within the nebula. Astronomers suspect that such companions account for the complex shapes and rings [ http://www.astro.washington.edu/balick/WFPC2/ ] of this and many other planetary nebulae. This cosmic infant is about 130 times the size of our own solar system and growing. It is 18,000 light-years distant, in the southern constellation Ara [ http://www.astro.wisc.edu/~dolan/constellations/ constellations/Ara.html ]. |
