Back in the 1980s, NASA's Voyager spacecraft made a brief flyby of Saturn's moons, providing us with a tantalising glimpse of new worlds. Now, the Cassini mission has finished the job, providing us with high-resolution, colour maps of Saturn's six icy moons.
This stunning image shows an energetic burst of gases being spat out at 2,000,000 mph from the centre of a galaxy, thanks to the immense pressures of stars forming at its core. The observation was made by a team of scientists from the University of Hertfordshire.
Back on November 23rd, the Pico do Fogo volcano on Cape Verde's Fogo island erupted. This image shows how that incident looked when it was captured by the Sentinel-1A satellite's radar sensors. Scientists are using these images to help them map the volcano's subsurface magmatic system.
