Although Enceladus and Saturn's rings are largely made up of water ice, they show very different characteristics. The small ring particles are too tiny to retain internal heat and have no way to get warm, so they are frozen and geologically dead. Enceladus, on the other hand, is subject to forces that heat its interior to this very day. This results in its famous south polar water jets, which are just visible above the moon’s dark, southern limb, along with a sub-surface ocean.

This NASA/ESA Hubble Space Telescope image shows the spiral galaxy NGC 4845, located over 65 million light-years away in the constellation of Virgo (The Virgin). The galaxy’s orientation clearly reveals the galaxy’s striking spiral structure: a flat and dust-mottled disk surrounding a bright galactic bulge.

Basking in Light Sunlight truly has come to Saturn's north pole. The whole northern region is bathed in sunlight in this view from late 2016 feeble though the light may be at Saturn's distant domain in the solar system.

Celebrating 20 Years of the Solar and Heliospheric Observatory (SOHO): After 20 years in space ESA and NASAs Solar and Heliospheric Observatory or SOHO is still going strong. Originally launched in 1995 to study the sun and its influence out to the very edges of the solar system SOHO revolutionized this field of science known as heliophysics providing the basis for nearly 5000 scientific papers.
