NGC 3132: The Southern
Ring Nebula
From
NASA’s Astronomy Picture of the Day
It's the dim star, not
the bright one, near the center of NGC 3132 that created this odd but beautiful planetary nebula.
Nicknamed the Eight-Burst Nebula and the Southern Ring Nebula, the glowing gas originated in the outer layers of a star like our Sun.
In this reprocessed color picture, the hot purplish pool of light seen
surrounding this binary system is energized by the hot surface of the faint star.
Although photographed to explore unusual symmetries, it's the asymmetries
that help make this planetary nebula so intriguing.
Neither the unusual
shape of the surrounding cooler shell nor the structure and placements of the
cool filamentary dust lanes running across NGC 3132 are well understood.
