The Fall of the Titans on Mount Othrys, the Titans most famously included the first twelve children of Gaia (Mother Earth) and Uranus (Father Sky). They ruled during the legendary Golden Age, and also comprised the first pantheon of Greek deities. Just as the Titan Cronus overthrew his father Uranus, the Titans were overthrown by Cronus's children (Zeus, Hades, Poseidon, Hestia, Hera and Demeter), the core Olympian deities, in the Titanomachy (or "War of the Titans"), at the end of which they were imprisoned in Tartarus, a Greek version of Hell. Their arrival there is depicted in the painting. The painting was bought by King
Atmosphere of Uranus Telescope and by ground-based telescopes equipped with adaptive optics systems (the Keck telescope and NASA Infrared Telescope Facility, for instance) made it possible for the first time to observe discrete cloud features from Earth. Tracking them has allowed astronomers to re-measure wind speeds on Uranus, known before only from the "Voyager 2" observations, and to study the dynamics of the Uranian atmosphere. The composition of the Uranian atmosphere is different from that of Uranus as a whole, consisting mainly of molecular hydrogen and helium. The helium molar fraction, i.e. the number of helium atoms per molecule of hydrogen/helium, was determined
