Summary

DescriptionMassive-galaxy-cluster-hubble-photo.jpg	English: "The galaxy cluster, named IDCS J1426.5+3508, is located a staggering 10 billion light-years away from Earth, and researchers spotted the behemoth because its gravitational field is so strong that it is warping the light coming from a galaxy behind it. Galaxy clusters are the most massive structures in our universe, and are made up of hundreds to thousands of galaxies that are bound together by gravity."
