GAL-CLUS-022058s is the largest and one of the most complete Einstein rings ever discovered in our Universe. The object has been nicknamed as the "Molten Ring", which alludes to its appearance and host constellation.

Einstein rings were first theorised to exist by Einstein in 1936, in his general theory of relativity , and this object’s unusual shape can be explained by a process called gravitational lensing, which causes light shining from far away to be bent and pulled by the gravity of an object between its source and the observer. In this case, the light from the background galaxy has been distorted into the curve we see by the gravity of the galaxy cluster sitting in front of it. The near exact alignment of the background galaxy with the central elliptical galaxy of the cluster, seen in the middle of this image, has warped and magnified the image of the background galaxy around itself into an almost perfect ring. The gravity from other galaxies in the cluster is soon to cause additional distortions.

Rings of Relativity: A Truly Strange and Very Rare Phenomenon

The narrow galaxy elegantly curving around its spherical companion in this image is a fantastic example of a truly strange and very rare phenomenon. This image, taken with the NASA/ESA Hubble Space Telescope, depicts GAL-CLUS-022058s, located in the southern hemisphere constellation of Fornax (The Furnace). GAL-CLUS-022058s is the largest and one of the most complete Einstein rings ever discovered in our Universe. The object has been nicknamed by the Principal Investigator and his team who are studying this Einstein ring as the “Molten Ring,” which alludes to its appearance and host constellation.

Un articolo pubblicato sulla rivista "The Astrophysical Journal" riporta uno studio sull'anello di Einstein soprannominato Anello Fuso per il suo aspetto "liquido" e perché è stato individuato nella costellazione della Fornace. Un team di ricercatori ha utilizzato osservazioni condotte con il telescopio spaziale Hubble e con lo strumento FORS 2 sul VLT in Cile dell'oggetto formalmente classificato come GAL-CLUS-022058s per studiare le sue caratteristiche fisiche. L'anello è in realtà una galassia la cui luce è stata distorta da una lente gravitazionale e, secondo le conclusioni dello studio, è lontana circa 9,4 miliardi di anni luce dalla Terra.

Scientists pinpoint age of molten 'Einstein ring'

New science from a stunning 2020 Hubble image illuminates the back story behind a shining loop of light.

The circle, also called an Einstein ring after the famous physicist who predicted its existence, came about due to a galactic-scale illusion. The galaxy this so-called “molten ring” curls around is called as GAL-CLUS-022058s and it is located in the Southern Hemisphere constellation of Fornax, the Furnace.

As scientists affiliated with the Hubble Space Telescope wrote in a statement, the big ring is actually a light smear created by a lensing effect that occurs when a foreground object with strong gravity magnifies the light of a more distant galaxy behind it. New research suggests that we are seeing the galaxy in the ring as it was about 9 billion years ago, when the universe was only about one-third its present age of 13.8 billion years.

“The detection of molecular gas, of which new stars are born, allowed us to calculate the precise redshift and thus gives us confidence that we are truly looking at a very distant galaxy,” Nikolaus Sulzenauer, a Ph.D. student at the Max Plank Institute for Radio Astronomy in Germany and a member of the investigation team, said in a statement released by the European Space Agency, which partners with NASA on the Hubble project.

“This was a time when the universe was going through a ‘baby boom,’ forming thousands of stars at a prolific rate. The magnified image of the galaxy gives astronomers a close-up glimpse into the distant past,” according to the Hubble statement.

Back when the photo was originally released in 2020, scientists said this was one of the most complete Einstein rings ever cataloged. After the photo’s publication, astronomers dug up archival data gathered by the European Southern Observatory’s Very Large Telescope to calculate the galaxy’s distance at 9.4 billion light-years. Further analysis allowed the team to examine stellar clumps of matter in the lensed galaxy, providing hints to its evolution.

“The extremely high rate of star formation in the brightest and very dusty early galaxies saw stars being born at a rate a thousand times faster than occurs within our own galaxy. This could help explain the rapid build-up of present day giant elliptical galaxies,” Hubble officials said in the same statement.

The initial Hubble observation was conducted by Saurabh Jha of Rutgers, The State University of New Jersey, while the lead investigator of the new research modeling the galaxy’s formation was Anastasio Díaz-Sánchez of the Universidad Politécnica de Cartagena in Spain.

Breathtaking 'Einstein ring' reveals views of a galaxy 9.4 billion light-years away

Breathtaking 'Einstein ring' reveals views of a galaxy 9.4 billion light-years away

One of the most spectacular Einstein rings ever seen in space is enabling us to see what’s happening in a galaxy almost at the dawn of time.

The smears of light called the Molten Ring, stretched out and warped by gravitational fields, are magnifications and duplications of a galaxy whose light has traveled a whopping 9.4 billion light-years. This magnification has given us a rare insight into the stellar ‘baby boom’ when the Universe was still in its infancy.

The early evolution of the Universe is a difficult time to understand. It blinked into existence as we understand it roughly 13.8 billion years ago, with the first light emerging (we think) around 1 billion years later. Light traveling for that amount of time is faint, the sources of it small, and dust obscures much of it.

Even the most intrinsically luminous objects are extraordinarily hard to see across that gulf of space-time, so there are large gaps in our understanding of how the Universe assembled itself from primordial soup.

But sometimes the Universe itself offers us a helping hand. If a massive object sits between us and a more distant object, a magnification effect occurs due to the gravitational curvature of space-time around the closer object.

Any light that then travels through this space-time follows this curvature and enters our telescopes smeared and distorted – but also magnified and duplicated. These are called Einstein rings, because the effect was predicted by, you guessed it, Albert Einstein.

The phenomenon itself is called gravitational lensing, and while it has given us some absolutely amazing images, it also affords us brilliant opportunities to combine our own magnification capabilities – telescopes – with those of the Universe to see things that might otherwise be too far to make out clearly, or at all.

The Molten Ring (formally named GAL-CLUS-022058s) is just such an Einstein ring, magnified by the gravitational field around a huge cluster of galaxies in the constellation of Fornax. So powerful is this effect that not only does the distant galaxy appear in four distorted images, it’s magnified by a factor of 20.

When combined with the Hubble Space Telescope, the resulting images are as detailed and sharp as observations taken with a telescope with a huge 48-meter aperture. From this, a team of researchers led by Anastasio Díaz-Sánchez of the Universidad Politécnica de Cartagena in Spain worked out that light from the galaxy has traveled 9.4 billion light-years.

This means it hails from a time in which star formation was happening at a tremendous rate – a thousand times faster than star formation in the Milky Way today. Learning more about this star-forming period in the Universe’s history can help us understand how today’s galaxies evolved. Usually we can’t see into galaxies back then very well, however; in addition to the distance, they’re very dusty.

With Hubble’s images, the researchers were able to model the lensing effect to rebuild the smears and duplications of the Molten Ring into the galaxy that created it.

“Such a model could only be obtained with the Hubble imaging,” Díaz-Sánchez said. “In particular, Hubble helped us to identify the four duplicated images and the stellar clumps of the lensed galaxy.”

This revealed that the galaxy is on what is called the main sequence of star forming galaxies – a correlation between galaxy mass and star formation rate – with new stars being born at a rate of 70 to 170 solar masses per year. The Milky Way, by contrast, has a star formation rate of just a few solar masses per year.

There’s a lot we still don’t know about the early Universe, and how the stars formed – but chance alignments such as the Molten Ring are helping us uncover their secrets.

The research has been published in The Astrophysical Journal.
