Hubble Peers Into Vast Distances
NASA’s Hubble Space Telescope peers deep into vast distances thanks to gravitational lensing. Gravitational lensing can help astronomers study objects that would otherwise be too faint or appear too small for us to view.
When a large object — such as a massive cluster of galaxies, as seen here — distorts space with its immense gravitational field, it causes light from more distant galaxies to travel along altered and warped paths that we can then observe with telescopes like Hubble.
