Saturn, its rings and their shadows are on display in this stunning image from NASA’s Cassini mission, showing dark bands across the planet’s northern hemisphere cloud tops, along with the elongated shadow of the moon Tethys near the planet’s north polar region. Other moons visible in the image include Dione (front right) and Enceladus (back right), a world that harbours a potentially habitable ocean under an icy crust. Cassini captured this view of Saturn on 6 December, 2007, at a distance of a million miles using red, green and blue spectral filters to produce a natural colour view.
Researchers at Southwest Research Institute (SwRI) and Queen’s University in Canada have unravelled the mystery of how Jupiter and Saturn likely formed using computer simulations. The discovery, which changes our view of how all planets might have formed, also suggests that the gas giants in the solar system probably formed before the terrestrial planets.
