Astronomy and Astrophysics Yale University

Yale's Kevin Schawinski talks about Galaxy Zoo, an online project that calls on ordinary people to review and classify images of distant galaxies. These "citizen scientists" have helped Schawinski and astronomers from other universities make important contributions to our understanding of the cosmos. They've now launched Galaxy Zoo 2, an even more ambitious and in-depth project.

Astronomer Kevin Schawinski discusses the finding of a unique astronomical object, "Hanny's Voorwerp," and the public volunteers spurring Galaxy Zoo.

Charles D. Bailyn, the Thomas E. Donnelley Professor of Astronomy and Physics discusses new findings and theories of black hole formation.

Priya Natarajan, Associate Professor of Astronomy and Physics at Yale, discusses the development and implications of the recent mapping of dark matter in the universe.
