Neptune Moons

We don't know if William Lassell had a celebratory beverage after he discovered Neptune's moon, Triton, but beer helped make the finding possible. Lassell was one of 19th century England's grand amateur astronomers. He used the fortune he made in the brewery business to finance his telescopes. He spotted Triton on Oct. 10, 1846 – just 17 days after a Berlin observatory discovered Neptune. Scientists using telescopes and spacecraft have found more moons, bringing the total number of moons orbiting this distant, giant world to 16. More ›
