Paleontologists have unveiled a remarkable new species of tyrannosaurine dinosaur from the Late Cretaceous epoch — a cousin of the fearsome predator Tyrannosaurus rex. Life reconstruction of the integument of Daspletosaurus horneri, based on the distribution of texture on the facial bones. The face in tyrannosaurs was covered by an extensive mask of large, flat scales, and regions of armor-like skin on the snout, jaws, and ornamental horns....

Showcase of the different types of changes identified in high-resolution images of 67P/Churyumov–Gerasimenko during more than two years of monitoring by ESA’s Rosetta spacecraft. The approximate locations of each feature are marked on the central context images. Dates of when the ‘before’ and ‘after’ images were taken are also indicated. Note that the orientation and resolution between image pairs may vary, therefore in each image set arrows point to the location of the changes, for guidance.

This enhanced-color view of Enceladus is largely of the southern hemisphere and includes the south polar terrain at the bottom of the image. Ancient craters remain somewhat pristine in some locales, but have clearly relaxed in others. Northward-trending fractures, likely caused by a change in the moon’s rate of rotation and the consequent flattening of the moon’s shape, rip across the southern hemisphere. The south polar terrain is marked by a striking set of ‘blue’ fractures and encircled by a conspicuous and continuous chain of folds and ridges, testament to the forces within Enceladus that have yet to be silenced. The mosaic was created from 21 false-color frames taken during Cassini’s close approaches to Enceladus on March 9 and July 14, 2005. Images taken using filters sensitive to UV, visible and IR light (spanning wavelengths from 338 to 930 nm) were combined to create the individual frames.
