Postcards from Saturn and its moons

cassini-lunas NASA's Cassini spacecraft has successfully completed its flyby over Saturn, the Moon Tethys, the Moon Dione, and the so-called "tiger stripes" , linear protrusions located in the south pole region of Enceladus, another of Saturn's moons. . The images sent by the probe after this mission reveal contrasts of light and darkness "worthy of painters like the master of chiaroscuro Caravaggio."

Enceladus' "tiger stripes" are actually giant fissures that spew jets of water vapor and hundreds of organic particles miles up into space. Cassini was also able to obtain a portrait of Enceladus in the bright arc of Saturn's atmosphere.

The flyby on August 13 was aimed at Enceladus, the geyser moon, but also included a close pass by Cassini to two other moons: Tethys and Dione. Raw images received include the best to date of Penelope crater on the icy moon Tethys , taken on August 14. Penelope is no less than 150 kilometers wide and is the second largest crater in Tethys. For its part, Dione's images highlight a rugged lunar surface full of impacts.

All images can be consulted in an extensive database that NASA has published here: http://saturn.jpl.nasa.gov/photos/raw/

Why are the two faces of the Moon so different? (new theory)

A new study posits that this unevenness is due to a colossal impact billions of years ago near the Moon's south pole.

Lyrids 2022: where and when to see the spring meteor shower?

This shower of stars is one of the most impressive of the year. Will the Moon let us observe it properly?

Do we all see the same Moon?

That's how it is. Lunar phases are an Earth-wide phenomenon. So why do photos of the Moon look different from different parts of the Earth?

Saturn, Venus and Mars will form a triangle in the sky this week

During this conjunction, these three planets will appear as a triangle in the east and will be brightest just before sunrise.

When was the first photograph of the Moon taken?

On this day 182 years ago, on March 23, 1840, John William Draper took what is considered the first successful photograph of a star.
