Sunburst Arc Doppelgangers Captured in Distant Region of the Universe

Sunburst Arc Galaxy

This image, taken with the NASA/ESA Hubble Space Telescope, shows a massive galaxy cluster, about 4.6 billion light years away. Along its borders four bright arcs are visible; these are copies of the same distant galaxy, nicknamed the Sunburst Arc.
The Sunburst Arc galaxy is almost 11 billion light-years away and the light from it is being lensed into multiple images by gravitational lensing. The Sunburst Arc is among the brightest lensed galaxies known and its image is visible at least 12 times within the four arcs.

Astronomers using the NASA/ESA Hubble Space Telescope have observed a galaxy in the distant regions of the Universe which appears duplicated at least 12 times in the night sky. This unique sight, created by strong gravitational lensing, helps astronomers get a better understanding of the cosmic era known as the epoch of reionization.

This new image from the NASA/ESA Hubble Space Telescope shows an astronomical object whose image is multiplied by the effect of strong gravitational lensing. The galaxy, nicknamed the Sunburst Arc, is almost 11 billion light-years away from Earth and has been lensed into multiple images by a massive cluster of galaxies 4.6 billion light-years away[1].

The mass of the galaxy cluster is large enough to bend and magnify the light from the more distant galaxy behind it. This process leads not only to a deformation of the light from the object, but also to a multiplication of the image of the lensed galaxy.

In the case of the Sunburst Arc, the lensing effect led to at least 12 images of the galaxy, distributed over four major arcs. Three of these arcs are visible in the top right of the image, while one counterarc is visible in the lower left — partially obscured by a bright foreground star within the Milky Way.

Hubble uses these cosmic magnifying glasses to study objects otherwise too faint and too small for even its extraordinarily sensitive instruments. The Sunburst Arc is no exception, despite being one of the brightest gravitationally lensed galaxies known.

The lens makes various images of the Sunburst Arc between 10 and 30 times brighter. This allows Hubble to view structures as small as 520 light-years across — a rare detailed observation for an object that distant. This compares reasonably well with star-forming regions in galaxies in the local Universe, allowing astronomers to study the galaxy and its environment in great detail.

Hubble’s observations showed that the Sunburst Arc is an analog of galaxies that existed at a much earlier time in the history of the Universe: a period known as the epoch of reionization — an era which began only 150 million years after the Big Bang.[2]

The epoch of reionisation was a key era in the early Universe, one which ended the “dark ages”, the epoch before the first stars were created when the Universe was dark and filled with neutral hydrogen[3]. Once the first stars formed, they started to radiate light, producing the high-energy photons required to ionize the neutral hydrogen[4].

This converted the intergalactic matter into the mostly ionized form in which it exists today. However, to ionize intergalactic hydrogen, high-energy radiation from these early stars would have had to escape their host galaxies without first being absorbed by interstellar matter. So far only a small number of galaxies have been found to “leak” high-energy photons into deep space. How this light escaped from the early galaxies remains a mystery.

The analysis of the Sunburst Arc helps astronomers to add another piece to the puzzle — it seems that at least some photons can leave the galaxy through narrow channels in a gas-rich neutral medium. This is the first observation of a long-theorized process[5]. While this process is unlikely to be the main mechanism that led the Universe to become reionized, it may very well have provided a decisive push.

Notes

[1] The official designation of the Sunburst Arc galaxy is PSZ1 G311.65-18.48.

[2] The further we look into space, the further back we look in time. This allows astronomers to study different epochs of the Universe, by studying objects at different distances.

[3] Ionization is the process of gaining or losing electrons to leave electrically charged particles. The era is known as reionisation because, after the Big Bang, matter formed first into protons and electrons. Then, during the era of recombination — about 380 000 years after the Big Bang — neutral hydrogen formed from these particles for the first time.

[4] While an ionised hydrogen atom consists of only the core of the atom (one proton) a neutral hydrogen atom contains a nucleus of one proton which is orbited by one electron.

[5] The paper outlining these observations will appear in Science on 8 November 2019.

  1. Remember that to each of such multiple pictures of the…..SAME object you could go by…….STREIGHT line but always …DIFFERENT , 12 times in DIFFERENT directions and always you would come to the…..SAME end point !!!!!!! ( and by the way in different time ) …. this is the proof that OTHER DIMENSIONS exists. – the fact that the 3 dim. Space is curved. 3 dimensions are curved in the fourth one….. ( ps ou have to have N+1 dimension if you want to divide a space of 3 dimension or it modifie etc

    I read your comments about dark matter and its effect in space, but according to Johnson, all of this is a waste of time, gentlemen, come and research the past of the earth, stop the research in space outside the galaxy, please, and take some time to know the civilizations The earth has been destroyed, take your time and the history of the solar system and the hundreds of planets that came to the sun with their stars over the course of tens of billions of years and hundreds of planets in the solar system collided with the sun with their stars collided with the sun and gas planets, how did you know all this? The impact of meteorites from planets that exploded and their elements collided with solar bodies, did you not notice this? Thousands of planets after they exploded hit the inner belts and outer belts of the solar system. Materials and elements from planets and stars that collided with gaseous planets. The hydrogen gas of those stars joined Uranus, Jupiter and Saturn, and from the last collisions between the stars of the arm of the galaxy, which collided with the gas planets, Jupiter still burns due to the collision of the stars of the arm of the galaxy. I have known this simple matter for many years. I took away secrets by referring to the creators and creators of the earth, who gave me messages in the Surahs of Evolution and the Lord about the shape of the continents that were formed by humans, the seas and continents that were on the earth a hundred million years before those humans before us. They lived and had several million years of civilization and their civilization was destroyed due to the collision of several planets with the sun, which means that human life was destroyed a hundred million years ago, but again, life from bacteria and single cells appeared on the earth, but humans on the earth worshiped God. When they removed the skulls of the people, the souls of those people came out completely from their heads and they were placed in special coffins. At the time of their death, and the souls of those people, when the bones of the skull were removed, it came out more complete and bigger, and those great spirits a hundred million years ago with Feeding on the oxygen of the air, they grew up in the sky and the earth and became the souls of the lords of the earth. You should know that if you do this experiment on the earth and remove the skulls of the bones of the dead and later put those human bodies in special coffins so that The soul of those people should make an exit way that after forty days or two months, when the soul comes out from the center of the cytoplasm tissues, it will be placed in a spherical tank made of glass. Because the soul is very light, when the body of the corpse leaks, it leaks and The gas of the cells of all the flesh tissue and the brain due to the disintegration of the cells and the production of a lot of gas, the commander of the cell, which is the tissue of the soul, from the central parts of the brain and the organs of the corpse, trillions of cells come out and move upwards, when the soul and the body of the soul, respectively They are formed in the cerebellum, they are gathered together in a certain order, and the shape of the human soul is exactly the same as the person who was alive. I have seen the curtain that the Lord and God have revealed. I will discuss this issue in the next comments. For now, may God protect you and I hope to meet you soon to tell you the story of the earthlings. Dr. Kesiri Kathiri, Tehran, Iran time 12:48 am nite noit
