I just discovered the Boston Globe's The Big Picture blog last week, and already it has become a favourite of mine. Its premise is simple: provide stunning, high-quality, and newsworthy photographs to viewers. The result is a new set of about 20 photographs with captions three times per week, and the photos include jaw-droppers like this one of a polar bear:

With a wonderful collection of images of international and current events, it is also possible to search the blog by month and category. Enjoy.
