The Hubble Space Telescope has detected a space object made up of six light points called “Einstein’s ring” or gravitational lenses, 3.4 billion light years from Earth. The ring formed when a “quasar” crossed the gravitational field of two distant galaxies. A quasar is a very bright core of an active galaxy, and its strong glow is produced by the enormous amounts of energy emitted by gas falling into the huge black hole at its center.
Albert Einstein predicted this phenomenon in 1915, that gravity is the result of huge objects deforming the fabric of the universe, which he called “space-time”.
This cosmic display, officially known as the “gravitational lens”, occurs when the gravitational field of a massive object in space twists space and deflects light from a distant object behind it, then produces a pattern. bull’s eye, or “Einstein’s ring”.
ESA astronomers explain: The light from the quasars is bent around the pair of galaxies due to their enormous mass, which gives this unique appearance and the pair of galaxies is surrounded by four quasars, when in fact , a quasar is located far from them.
Since then, experts have been able to test his theory of general relativity in the solar system and prove his revolutionary theory to be true.
“General relativity predicts that massive objects distort space-time, which means that when light passes near another galaxy, the path of light is deflected”, Thomas Collette, of the Institute of Cosmology and gravitational survey from the University of Portsmouth, which discovered another Einstein ring in 2018, “Two galaxies are aligned along our line of sight, which could lead to a phenomenon called a strong gravitational lens, where we see several background galaxy images. “
