Dark matter just became even more mysterious

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.
Dark matter cannot be directly seen because it is composed of particles that do not absorb, reflect, or emit light. This material makes up about 85 percent of the Universe.
