One of the most surprising and intriguing finds during the decade-long Cassini mission has been the discovery of geysers on the Moon Enceladus. Originally spotted in 2005, scientists have spent the last decade trying to understand how they work. And now they finally have a working model. How does an eruption on a frigid Moon last so long? Eruptions on Earth are not long-lived, and if they are, they are very spread out. For Enceladus to have a ton of localized geysers in the South polar region, you need some pretty specific scenarios. Aside from the fact that a constant stream of material could clog...
Have you ever seen those amazing composite images that people will post, showing the same picture every day or every year for a long period of time. We see how children age, how people transform their bodies, and how their day to day experiences, though seemingly small, add up to incredible changes as the years go by. I personally love time-lapse photography, representing a long period of time in a shorter instance. For me the beauty is showing those changes that are subtle in human experience and communicating them in a way that shows how significant they are when we...
For years there has been talk of a subsurface ocean present within Saturn’s icy moon Enceladus. Many have simply assumed it to be fact, but the reality is, something so complex on a world so far away is very difficult to prove conclusively. But now, using data from over a decade of observations by the Cassini spacecraft, mission scientists have shown conclusively that Enceladus must have a global ocean beneath a surface of ice. Previous data analysis suggested that there was a lens-shaped liquid ocean beneath the south polar region of the planet, giving a source for the observed plumes...
