Among the scientific objectives of the Hubble Space Telescope is also the study of the planets of the solar system. In recent years, the device has observed external worlds many times in the framework of the OPAL program.
This program provided a new vision for Uranus - the seventh planet in the system from the Sun. Early observations using Hubble produced a lot of interesting data about the cold giant. In 2006, managed to get a photo where the satellite Ariel and his shadow crossed the face of the planet. In addition, in 2011, weak auroras could be observed in the atmospheric layer.
Collected for several years, observations have also helped to study the weak ring system, since its slope has changed relative to the Earth's orbit. A new picture was taken on a wide-angle camera 3 and provides an opportunity to explore the planet even better.
