The best images from Cassini for 2015

With all the attention to New Horizons and Pluto lets not forget the veteran spaceship Cassini which makes wonders around Saturn and sometimes it seems as there is an artist photographer sitting there to get these great compositions.
Cassini is now on its 219's Rev around Saturn. The orbit is very elliptical and spans from about 200,000km to over 2,000,000km. Such an orbit is required to measure Saturn's gravitational field and also give chance to flybys around the moons. Each Rev is well planned in advance and is fully using the time to observe Saturn and the moons.
Here are some of the best photos of 2015
You can see many more at Cassini's website and I've added a link for each photo for more explanations and details in that website.

Lets start with an old photo which is not very familiar. This is a very known object from a completly different angel.

This is an old photo of Jupiter when Cassini passed near him in the previous decade. The angle is unique. Never before we saw Jupiter from down under! The great red spot and the entire clouds' bands are visible in this magnificent image.


What do you see in the following unreal picture? Obviously you see the ring but what is behind the ring? It is the ring shadow in Saturn surface! Cubist art in its best.

And Tethys looks just like the death star from star-wars (Me and the children are eagerly waiting for episode VII!)

Dione is beautifully aligned on Saturn ring which is extremely narrow in this photo. The dark silhouette of Saturn is a great background.

 Three moons in one shot and all of them thin crescent. hoe can that happen?

Who's who? The large object is Saturn! look carefully for the thin ring in the right middle. The small object is Titan which is a very large moon but small in front of giant Saturn.
