Hurricanes are an incredible force of nature, and these huge rotating vortexes of wind are an amazing sight when viewed from space. But Earth is not the only planet that has hurricanes, and there is one on Saturn that dwarfs any on our own planet. Now, the Cassini spacecraft has taken more breath-taking colour images of this colossal wind storm.

Cassini sees meteor impacts in Saturn’s rings

Meteors flashing across the sky are a common sight here on Earth, but of course they are not limited to only our planet; these bits of rocky debris, smaller pieces of asteroids and comets known as meteoroids, can be found just about everywhere in the solar system (becoming meteors when entering and burning up in the atmosphere). Now, the Cassini spacecraft has observed similar impacts occurring in another very different and far-away place: the rings of Saturn!

There’s a lot of water in Jupiter’s atmosphere, thanks to comet impact

The impact of comet Shoemaker-Levy 9 into Jupiter in 1994 was a spectacular event for astronomers. The scars in Jupiter’s atmosphere lasted for weeks afterward; while those have long since faded, there are still other features of the impact visible even now, it was announced last Tuesday.

There is some more exciting news from the Kepler space telescope mission – as announced in a NASA press briefing this morning, three more planets have been detected orbiting in their stars’ habitable zones. Larger planets have been found already in this zone around various stars, but what makes this newest discovery so compelling is that these new planets are the smallest found so far in this zone, so-called “super-Earths.” Two of them may even be covered by oceans!
