November 6, 2009--A deep new picture of the Ring Nebula released by the Calar Alto Observatory in Spain shows the looping filaments of gas coming from the nebula's central star in unprecedented detail. A more distant spiral galaxy sits in the upper right. The rosy-colored nebula, which lies about 2,000 light-years from Earth, is the remnant of a sunlike star that expelled its outer shells of gas as it died, leaving behind a dense core known as a white dwarf that is surrounded by layers of glowing rings.
