On August 11th in Science History, one significant event that occurred was the launch of the Asaph Hall's discovery of Mars' moons in 1877.
In the late 19th century, American astronomer Asaph Hall was observing Mars through the 26-inch (66 cm) refracting telescope at the United States Naval Observatory. On the night of August 11th, 1877, Hall noticed a faint object near Mars. He initially thought it might be a star, but further observations revealed that the object was actually orbiting the Red Planet.
Hall had discovered Deimos, the smaller and outermost of Mars' two moons. Six days later, on August 17th, he spotted Mars' larger moon, Phobos. These discoveries were groundbreaking because they were the first moons discovered around a planet other than Earth.
The names Phobos and Deimos, meaning "fear" and "panic" in Greek mythology, were aptly chosen as they are the twin sons of Ares (Mars in Roman mythology) and Aphrodite (Venus).
Interestingly, the discovery of these moons almost didn't happen. Hall had been searching for Martian moons for some time, and he was about to give up when he decided to persevere for a few more nights. His wife, Angelina, also encouraged him to continue his search, and her support played a crucial role in the discovery.
The discovery of Phobos and Deimos not only expanded our understanding of the Martian system but also sparked further interest in the study of the Red Planet and the search for moons around other planets in our solar system.
