What type of cloud is that? This retreating cumulonimbus cloud, more commonly called a thundercloud, is somewhat unusual as it contains the unusual bumpiness of a mammatus cloud on the near end, while simultaneously producing falling rain on the far end.

Looping through the Jovian system in the late 1990s, the Galileo spacecraft recorded stunning views of Europa and uncovered evidence that the moon’s icy surface likely hides a deep, global ocean. Galileo’s Europa image data has been remastered here, with improved calibrations to produce a color image approximating what the human eye might see. Europa’s […]

What does Comet Leonard look like up close? Although we can’t go there, imaging the comet’s coma and inner tails through a small telescope gives us a good idea. As the name implies, the ion tail is made of ionized gas — gas energized by ultraviolet light from the Sun and pushed outward by the […]
