Hubble Space Telescope looks into center of vast galaxy cluster almost 9 billion light-years away

NASA's Hubble Space Telescope peered into the center of a vast galaxy cluster in a beautiful new image. 

The European Space Agency (ESA) said the cosmic giant – called eMACS J1823.1+7822 – can be identified by the distortions in space-time surrounding it. 

The mass of the cluster has caused the images of background galaxies to be gravitationally lensed. 

Gravitational lensing occurs when a celestial object has such a massive gravitational pull that it warps time and space around it, bending the light from a more distant object and magnifying it.
