This image from NASA’s Galileo spacecraft shows Io. There are rugged mountains several miles high, layered materials forming plateaus, and many irregular depressions called volcanic calderas. Several of the dark, flow-like features correspond to hot spots, and may be active lava flows. There are no landforms resembling impact craters, as the volcanism covers the surface with new deposits much more rapidly than the flux of comets and asteroids can create large impact craters. The picture is centered on the side of Io that always faces away from Jupiter; north is to the top. Image credit: NASA / JPL / University of Arizona.

This artist’s concept of a young solar system shows gas giants forming first, while the gas nebula is present. Prof Martin Duncan and co-authors used computer simulations to nail down how Jupiter and Saturn evolved in our own Solar System. These calculations show that the cores of gas giants likely formed by gradually accumulating a population of ‘planetary pebbles’ - icy objects about a foot in diameter.

This global view of Io was obtained by NASA’s Galileo spacecraft on 19 September 1997 at a range of more than 500,000 km (310,000 miles). In this image, deposits of sulfur dioxide frost appear in white and grey hues while yellowish and brownish hues are probably due to other sulfurous materials. Bright red materials and ‘black’ spots with low brightness mark areas of recent volcanic activity and are usually associated with high temperatures and surface changes.
