Saturn’s Rings Could Be Gone in Just 100 Million Years – Gizmodo

Image: NASA/JPL-Caltech/Space Science InstituteWith its extensive system of rings, Saturn is among the most beautiful planets in the Solar System. Sadly, it’s beauty may be fleeting, according to new research. Saturn’s rings are dissolving faster than scientists expected, according to the study, and they could be gone in 100 million to 300 million years—a cosmological…

Artist rendering of a short-tailed pterosaur feathers and all. (Credit: Yuan Zhang/Nature Ecology & Evolution) The discovery of novel filaments on two species of pterosaur suggests that the extinct flying reptiles had complex coats of “feathers” and fuzz, say the authors of a new study. The presence of these apparent pterosaur feathers may indicate that the ancestor of…
