6 years of Saturn
by Rafael Defavari
http://rafaeldefavari.com

This image shows the tilting of Saturn towards Earth during the last 6 years - between Dec/2010 and April/2015 - since I started in astrophotography.

The bright spots near the planet's disk are some of its closest moons, appearing between the images. Despite the low quality of the first image, it is possible to observe a white smudge at Saturn's atmosphere - that was the great 2010 storm, that could be observed during a few months from Earth through telescopes.

The difference in quality between the images is due equipment upgrades and improvement of capture and processing techniques.

This time it's not an image only mine, but a picture made by summing the work more Italian and foreign amateur astronomers and then elaborated by Giuseppe Donatiello. Thanks to the sum of many pictures you could get a high signal-to-noise ratio, so as to highlight all the plots of this beautiful Nebula. authors of original image: Claudio Bottari, Ruggiero Carpagnano, Giuseppe Donatiello, Marco Favuzzi, Andrew Genualdi, Rolando Ligustri, Tommaso Martino, Federico Pelliccia, Andrea Pistocchini,Bert Scheuneman, Stefano Schirinzi, Tim Stone, Paolo Zampolini. total exposure time: 40 hours

Argimusco twilight with Venus Taurus Cassiopea and Pleiades

Copyright: Dario Giannobile Between the Mediterranean sea and the volcano Etna, the upland of Argimusco stands towards the sky. An impressive and evocative place where different monoliths emerge from the ground. Recent studies demonstrated that the site has been used as a natural calendar in order to measure the seasons' cycle. In the next coming years the Argimusco could become the Mediterranean Stonehenge.

Primal Light by The Art of Night, on Flickr

When primal man first walked this Earth he would have been able to travel by starlight at night. There would have been no light pollution, and the bright galactic centre of the Milky Way would have been an incredible sight to see in the night sky. Thankfully there are still locations on Earth were you can experience this, but with two-thirds of the U.S. population and more than one-half of the European population having already lost the ability to see the Milky Way, it an experience that will be missed by many.
