... Impact craters and associated concentric rings are about the only features to be found on Callisto. ... It has a bright central region that is 600 kilometers in diameter, and its rings extend to 3000 kilometers in diameter. ... This image shows the heavily cratered surface of Callisto. ... Also visible is a fresh, sharp-rimmed crater some 90 km (56 miles) across named Igaluk (center left third of picture), and a bright zone in the south polar area (bottom of image) which could be an impact scar. ...

... We present a comparison of the surface density of young stars (неБ‹†) and dust surface density (неdust) across NGC 346 (N66) in 115 independent pixels of 6 ц— 6 pc2. ... We convert неdust to gas surface density (неgas) and неБ‹† to star formation rate (SFR) surface densities (неSFR), using simple assumptions for the gas-to-dust mass ratio and the duration of star formation. ... On small scales the неSFR derived using Hн± systematically underestimates the count-based неSFR, by up to a factor of 10. ...
