Hubblecast 70: Peering around cosmic corners

The ESA astronomy podcast, bringing you the latest from the Hubble Space Telescope

6 December 2013

Last month saw the inauguration of a new Hubble observing program: Frontier Fields. This will use the powerful magnifying properties of massive galaxy clusters to peer even deeper into the space around us. Hubblecast 70 takes a look at this phenomenon — known as gravitational lensing — exploring how it works, and how it can help us to uncover the secrets of the very distant Universe.
