Hubble detects an impressive Einstein ring | Digital Trends Spanish

A new photograph from the Hubble Space Telescope shows an impressive “Einstein ring” at a distance of billions of light years from Earth.

The phenomenon is named after the famous physicist, who predicted that gravity could bend light.

The round object that can be seen in the center of the image shared by the European Space Agency (ESA) corresponds to three galaxies that appear as if they were seven.

The farthest galaxy, a very bright one with a gigantic hole at its center, is about 15 billion light-years from Earth.

Although at that distance this object should be invisible, we can appreciate it, since its light is bent by the two galaxies in front, about 3 billion light years away.


Thus, its image is shown as five different places: four times in the ring and once in its center, although it can only be detected in the numerical data of the telescope.

According to scientists, Einstein’s rings are much more than just a pretty phenomenon, as their gravitational lenses allow astronomers to look much further into the depths of the universe.

“They are presumably proof that there is more material in the closer galaxies than meets the eye, and that probably means dark matter,” says Ed Krupp, an astronomer and director of the Griffith Observatory in Los Angeles.

According to the researcher, its distribution can “help to illuminate the identity and distribution of dark matter and the relativistic geometry of the entire universe.”
