The Sun is incredibly dynamic — something that's difficult to convey properly in the pages of a book or magazine. If you watch a major solar flare through a telescope, it will often change from one minute to the next. Time-lapse movies compress the time scale, allowing you to see this motion directly. In...

These spacecraft encounters have yielded a treasure trove of detailed images and data. To study an asteroid's surface completely and in detail, it's necessary to orbit the asteroid rather than just photograph it in...
