During the last decade, amazing advances have been made in the tools and techniques used to research our nearest star. For example, solar scientists now have at their command an array of space weather satellites and other spacecraft that enable researchers to see in much greater detail the dynamic moment-by-moment activity of our Sun. With precision instruments, scientists look for patterns and cycles, causes and effects, which help us understand the way our Sun works.
A new patterns that their eyes might miss. These data are usually represented visually, as numbers or graphs. University of Michigan researchers have “sonified” the data, creating an acoustic, or musical, representation of it.
