Today’s Video of the Day from NASA Goddard describes a puzzling new discovery in the way that dark matter behaves in space. 

In a phenomenon known as gravitational lensing, dark matter distorts and magnifies the space surrounding large galaxy clusters.

The scientists found that across three different galaxy clusters, the concentration of dark matter was so immense that the galaxies produced lensing effects ten times stronger than what was expected.
