GREENBELT, Md., Jan. 13 (UPI) -- NASA says an image from the Hubble Space Telescope of a nebula suggests a giant star at its center is destined to explode as a supernova.
At the center of the cosmic object, dubbed SBW1, is a star that was originally 20 times more massive than our sun and is now encased in a swirling ring of purple gas, the remains of a distant time when it cast off its outer layers via violent pulsations and winds.
