Some of the most intractable scientific problems involve natural and physical processes that span many scales and disciplines, from atoms to organs, and from quarks to galaxies. Developing coherent theories that can describe these fundamental phenomena will be crucial to understanding the origins of the Universe and life on Earth. Researchers are inventing solutions to link the vast with the tiny.

Astronomers have discovered never-before-seen structures within a dusty disc surrounding a nearby star. The fast-moving wave-like features in the disc of the star AU Microscopii are unlike anything ever observed, or even predicted, before now. The origin and nature of these features present a new mystery for astronomers to explore.

The center of our Milky Way galaxy is a mysterious place. Not only is it thousands of light-years away, it's also cloaked in so much dust that most stars within are rendered invisible. Harvard researchers are proposing a new way to clear the fog and spot stars hiding there. They suggest looking for radio waves coming from supersonic stars.
