From enraptured voles and space robots on the moon to brain gears and dense objects, it was a heck of a week in science. Let's take a look at some of the most interesting developments over the past seven days.
This image from the NASA/ESA Hubble Space Telescope is teeming with color and activity. It features a relatively close star-forming region known as IRAS 16562-3959, which lies within the Milky Way about 5,900 light-years ...
