Just add water: scientists explain Saturn’s powerful thunderstorms

Thunderstorms are a powerful force of nature, but the ones we experience on Earth are dwarfed by the ones on the gas giant planet Saturn. They are huge and can be larger than Earth itself, and now scientists think they know why they tend to appear most prominently every 20-30 years, encircling the entire planet with intense lightning and massive cloud disturbances.

Cassini’s best-ever view of Saturn’s amazing hexagon

The solar system is full of many planets and moons, each with their own unique characteristics and features, some of which have never been seen anywhere else. One such oddity is found on Saturn – a giant hexagon-shaped jet stream surrounding the planet’s north pole. It is a natural feature in Saturn’s atmosphere, although the near-perfect six-sided formation might make you look twice. Now, the Cassini spacecraft has taken the best-ever images of this hexagon, it was announced yesterday.

Stunning new image from Cassini of Saturn – and Mars, Earth and Venus too!

Beautiful panoramic view of Saturn, some of its moons, and even some of the inner planets including Earth, as imaged by Cassini on July 19, 2013 as part of The Day the Earth Smiled event. Image Credit: NASA/JPL-Caltech/SSI

The Cassini spacecraft has taken another stunning new panoramic image, released yesterday, showing Saturn and its rings in all of their glory. It has done this before, including ones showing the Earth and Moon in the far distance, as tiny specks of light. But this new image is even better; not only does it again show Saturn and its rings beautifully backlit against the Sun in natural color, but this one also shows Mars and Venus, as well as the Earth and Moon!

This stunning view of Saturn is one that can never be seen from Earth; it was taken by the Cassini spacecraft, still orbiting the huge ringed planet, from high above the equatorial plane on October 10, 2013. Only in such a view can the planet itself be seen as separate from the surrounding rings. This composite image was made from 36 individual images. Beautiful!
