Today's giant telescopes offer amazing views of distant worlds. But it doesn't take modern technology costing millions to capture the awesome beauty and mystery of the night sky.
Case in point: 19th-century French entomologist-turned-astronomer Etienne Leopold Trouvelot (1827-1895), who created more than 6,000 astronomical illustrations while working for the Harvard College observatory. The illustrations, which span from 1872 until his death in 1895, depict a wide range of objects, from his clean, minimalist Jupiter to his realistic lunar volcanos.
