A stunning deep-space image reveals Abell 7, a faint planetary nebula approximately 1,800 light-years away in the constellation Lepus. Its subtle, spherical form, about 8 light-years across, is highlighted against a backdrop of Milky Way stars and distant galaxies. Long exposures and narrowband filters showcase the nebula's intricate internal structures, composed of hydrogen, sulfur, and oxygen emissions. The central star, a 10-billion-year-old white dwarf, is visible at the heart of this 20,000-year-old celestial wonder.
