NASA's Cassini Captures Another Breathtaking Picture Of Saturn's Moons Janus And Tethys

NASA's Cassini spacecraft is on something of a roll at the moment having taken yet another photo that leaves you wondering about our place in the universe.

This time the orbiting spacecraft has captured the incredible differences between Saturn's moons picturing both Janus and Tethys in the same shot with Saturn's enormous rings slicing through the centre of the image.

Starkly contrasting with the blackness of space you can see Tethys' 600-mile diameter towering above the lumpy shape of Janus which measures just 111 miles across.

Why are they so different? Quite simply when it comes to being a moon, size definitely does matter. Tethys is thankfully large enough that it can produce its own gravity strong enough to mould it into a spherical shape.

Janus on the other hand is just too small and so with little to no gravity the moon remains utterly unchanged.

What's so impressive about Cassini's shots has been the composition - managing to capture Saturn and its moons in such a way that not only are they scientifically useful but almost always happen to look absolutely stunning.
