Saturn has 62 natural satellites. Here are some features of some of its moons, with mountains, valleys, and striking marks on their surfaces, often marked by asteroid bombardments causing small, huge craters.
Iapetus - Equatorial ridge
Iapetus’s equatorial ridge was discovered when the Cassini spacecraft imaged Iapetus on 31 December 2004. Peaks in the ridge rise more than 20 km above the surrounding plains, making them some of the tallest mountains in the Solar System. The ridge forms a complex system including isolated peaks, segments of more than 200 km and sections with three near parallel ridges.
Tethys - Odysseus crater
Odysseus is the largest crater on Saturn’s moon Tethys. It is 445 km across, more than 2/5 of the moon’s diameter, and is one of the largest craters in the Solar System.
Tethys - Ithaca Chasma
Ithaca Chasma is a valley (graben) on Saturn’s moon Tethys, named after the island of Ithaca, in Greece. It is up to 100 km wide, 3 to 5 km deep and 2,000 km long, running approximately three-quarters of the way around Tethys’ circumference, making it one of the longer valleys in the Solar System. Ithaca Chasma is approximately concentric with Odysseus crater.
Tethys - Red arcs
Unusual arc-shaped, reddish streaks cut across the surface of Saturn’s ice-rich moon Tethys in this enhanced-color mosaic. The red streaks are narrow, curved lines on the moon’s surface, only a few miles (or kilometers) wide but several hundred miles (or kilometers) long.
Rhea - Inktomi crater
Inktomi, also known as The Splat, is a prominent rayed impact crater 47.2 kilometres (29.3 mi) in diameter located in the southern hemisphere of Saturn’s moon Rhea.
Mimas - Herschel Crater
Herschel is a huge crater in the leading hemisphere of the Saturnian moon Mimas, on the equator at 100° longitude. It is so large that astronomers have expressed surprise that Mimas was not shattered by the impact that caused it. It measures 139 kilometres (86 miles) across, almost one third the diameter of Mimas. If there were a crater of an equivalent scale on Earth it would be over 4,000 km (2,500 mi) in diameter – wider than Canada – with walls over 200 km (120 mi) high.
Enceladus - Surface with fractures
Close up of one of the ‘tiger stripes” or fissures called Baghdad Sulcus. Both heat and occasional geysers issue from this formidable crack. Some of the material coating the landscape may be snow condensed from vapor. This closeup of the surface of Enceladus on November 21, 2009, viewed from approximately 1,260 miles (2,028 kilometers) away.
Dione - Contrasts
This image from NASA’s Cassini spacecraft shows a part of Dione’s surface that is covered by linear, curving features, called chasmata. One possibility is that this stress pattern may be related to Dione’s orbital evolution and the effect of tidal stresses over time. This view looks toward the trailing hemisphere of Dione.

I don’t know what it is about Star Wars but even if it’s not your biggest fandom, it still has the funniest memes by a long shot I mean “look at all the fucks i give anakin” and “your poncho is a piece of junk” and anakin hates sand it’s all just 1000% pure class
this is a real deleted scene from revenge of the sith
No. Just no. Ok?
So I used to make this joke all the time. Now I have chronic tinnitus. For those of you who don’t know what that is, it’s nerve damage in your ears which often comes as a result of being constantly exposed to very loud noise for a long period of time. The nerve damage results in a constant ringing/buzzing in your ears. So far there’s no cure. The severity of it varies, and I’m lucky to have a mild case, which I can barely hear during the day and is easy to block out at night. That said, loads of people with tinnitus aren’t so lucky. Severe tinnitus can’t be blocked out. Those who suffer from it also suffer from severe loss of sleep, depression, anxiety…. the list goes on. Tinnitus also comes with a degree of hearing loss in most cases, making it even harder to ignore. In fact, some people with severe tinnitus kill themselves just to make the ringing stop. Tinnitus can be so severe that it drives a person to suicide. Chronic tinnitus used to mostly be prevalent in older people who worked for years with loud machinery etc, but all of a sudden it’s becoming more common in our generation. Why? Because of people, like me, who listened to their music too goddamn loudly through their headphones.
Deaf by the time you’re 20? Please. That’s the least of your worries.
