Stephen O'Meara is well known in the astronomy community for his remarkable skills as a visual observer. He was the first to sight Halley's Comet on its 1985 return and also the first to determine the rotation period of the distant planet, Uranus. He has been recognised by the International Astronomical Union, which named Asteroid 3637 O'Meara in his honour. The author of several books, a regular contributor to astronomy journals, and a National Geographic-funded explorer, he also works as a photographer and videographer for National Geographic. He lives in Botswana with his wife, Deborah, where they run yoga and stargazing safaris.
