Abell 2218—A Massive Gravitational Lens

Lecture no. 10 from the course: Experiencing Hubble: Understanding the Greatest Images of the Universe

Abell 2218—A Massive Gravitational Lens

Taught by Professor David M. Meyer | 30 min | Categories: The Great Courses Plus Online Science Course

One of the consequences of Einstein's general theory of relativity is evident in Hubble's picture of the galaxy cluster Abell 2218. Investigate the physics of this phenomenon, called gravitational lensing, and discover how Hubble has used it to study extremely distant galaxies as well as dark matter.
