This planetary nebula, also known as the "Eight-Burst" Nebula because of its figure-8 appearance through amateur astronomer telescopes, is visible in the southern hemisphere. NGC 3132 is nearly half a light year in diameter and 2,000 light years away. Gases are moving away from the dying star at its center at a speed of nine miles per second (14.4 km/s).
