A Sheep in Wolf-Rayet's ClothingWashington DC (SPX) Feb 20, 2012 It's well known that the universe is changeable: even the stars that appear static and predictable every night are subject to change. This image from the NASA Hubble Space Telescope shows planetary nebula Hen 3-1333. Planetary nebulae have nothing to do with planets - they actually represent the death throes of mid-sized stars like the sun. As they puff out their outer layers, large, irregular globes of glowing gas expand around them, which appeared planet-like through the small telescopes that we ... read more |
