Arthur Eddington (1882-1945) was an English astronomer who first described the internal structure of a star. EGG NEBULA The Egg nebula (CRL2688) is a planetary nebula about 3,000 light-years from Earth. This huge cloud of dust and gas is expanding outwards at very high speeds. It was formed by a red giant star a few hundred years ago (this red giant was once a Sun-like star). Dust obscures our view of the star within.
