Hubble captures a beautiful image of ‘Einstein ring’ from warped quasar light

By Aswin Kumar

NASA’s Hubble Space Telescope image shows an “Einstein ring” whose existence was predicted in 1915 by German Physicist Albert Einstein.

In the image, two galaxies, around 3.4 billion light-years from Earth, warp and deflect light from an even more distant galaxy behind them. Hubble’s sensitivity and high resolution allow it to see that cannot be detected with ground-based telescopes.

The image shows six luminous spots of light as predicted by Albert Einstein. Four among them are forming a circle around a central clustered pair.

“The light from the quasar has been bent around the galaxy pair because of their enormous mass, giving the incredible appearance that the galaxy pair are surrounded by four quasars — whereas in reality, a single quasar lies far beyond them,” European Space Agency (ESA) officials wrote in a statement


A quasar is an extremely luminous active galactic nucleus, in which a supermassive black hole with massive radiation and they are trillion times luminous than the brightest star.

Einstein’s theory of general relativity describes the way massive objects warp the fabric of the universe, called space-time. Einstein discovered that Gravity, isn’t produced by a invisible force but it is our experience of space-time curving and distorting in the presence of matter and energy.

This curved space sets the rules for how energy and matter move, light traveling through a highly curved region of space-time, like the space around the two enormous galaxies, also travels in a curve — bending around the galaxies and splaying out into a halo.
