Infant Galaxy Showcases Star Systems in the Early Universe

A rare cosmic zoom lens, which uses the gravity of a large mass to magnify light from distant objects, has allowed a team of US and European astronomers to spot a galaxy so remote that its light was emitted 490 million years after the Big Bang, which is 3.6% of the Universe’s current age.

  1. Just to add a quick note. Gravitatonal lensing can cause a magnifying effect, but, importantly, what actually occurs is the warping of space-time due to a gravitational mass. Clusters will, naturally, causes a greater warping of space-time. Under normal circumstances, light follows straight paths or geodesics. However, as the space-time is warping these geodesics can bend and warp, thus causing light to form rings where light is passing by a cluster. This is a very cool astronomical technique nonetheless!
