Gravitational Lensing

Gravitational lensing occurs when light from a distant galaxy is bent by the gravitational pull of an intervening astronomical object. In this image assembled from multiple observations by the Hubble Space Telescope a relatively nearby galaxy cluster (MACSJ0138.0-2155) has lensed the galaxy (MRG-M0138) which is located 10 billion light-years from us.

  1. The Earth is only 4.5 billion years old. It’s hard to wrap my mind around the fact that we are seeing light from a galaxy that is over twice as 9ld.
