Hubble discovered Einstein’s ring in the Gulf newspaper

The Hubble Space Telescope has detected a space object with six bright spots called “Einstein’s ring” or gravitational lenses 3.4 billion light years away from Earth. A quasar is the brightest center of an active galaxy, and its strongest glow is formed by the large amount of energy emitted by gas falling into the large black hole at its center.

Albert Einstein predicted this event in 1915, when gravity was the result of large objects decomposing the fabric of the universe, which he called “space time”.

Officially known as “gravitational lensing”, this cosmic scene twists the gravitational field of a large object in space, diverting the light of a distant object behind it, and then creating a bull-eye shape or “Einstein’s ring”.

ESA astronomers explain: The light coming from the quasars orbits the galaxy pair, giving it a unique appearance due to its enormous mass, and the galaxy is surrounded by four quasars, in fact one quasar is far away from them.

Since then, experts have been able to test his general theory of relativity within the solar system and prove that his fundamental theory is true.

“General Relativity Prediction Significantly massive objects distort space-time, that is, when light passes near another galaxy, the path of light is diverted,” said Thomas Colette, of the University of Portsmouth Astronomy and Gravity Institute, who discovered another Einstein ring in 2018. The two galaxies are aligned along our line of sight, and this leads to an event called strong gravitational lensing, where we see multiple images of the background galaxy.
