Discovery and exploration of the Solar System Domenico Cassini later discovered four more moons of Saturn and the Cassini division in Saturn's rings. Edmond Halley realised in 1705 that repeated sightings of a comet were recording the same object, returning regularly once every 75–76 years. This was the first evidence that anything other than the planets orbited the Sun. Around this time (1704), the term "Solar System" first appeared in English. In 1781, William Herschel was looking for binary stars in the constellation of Taurus when he observed what he thought was a new comet. Its orbit revealed that it was a new planet, Uranus, the first
Solar power in Australia the state government announced a new round of finance for renewable energy projects which included a Planet Arc Power - Schneider Electric development of a $13.9m solar PV and battery project at a major distribution centre in Adelaide’s North. The project includes a micro-grid management system optimising 5.7MW of solar PV coupled with 2.9MWh of battery storage. The University of South Australia will develop 1.8MW of ground and roof mounted solar PV at its Mawson Lakes campus. At the Heathgate Resources Beverley mine there are plans for a relocatable 1MW of solar PV paired with a 1MW/0.5MWh battery which will
