The Hubble Space Telescope has identified at least 12 images of the Sunburst Arc, a galaxy that is located slightly less than 11 billion light-years away. The Sunburst Arc is among the brightest lensed galaxies known and its image is visible at least 12 times within the four arcs.Three arcs are visible in the top right of the image, the fourth arc in the lower left. It is one of the brightest lensed galaxies, lensed by a cluster 4.6 bly away. The galaxy, nicknamed the Sunburst Arc, is almost 11 billion light-years from Earth and has been lensed into multiple images by a massive foreground cluster of galaxies 4.6 billion light-years away.

While this process is unlikely to be the main mechanism that led the Universe to become reionised, it may very well have provided a decisive push. 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. 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. 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.

[1] The official designation of the Sunburst Arc galaxy is PSZ1 G311.65-18.48. Nicknamed the Sunburst Arc, PSZ1 G311.65-18.48 is no exception, despite being one of the brightest gravitationally lensed galaxies known. .ESA/Hubble Information Centre.

NASA’s Hubble space telescope has captured an image of a distant galaxy, 11 billion light-years away.The galaxy, nicknamed Sunburst Arc, was duplicated at least 12 times in the image due to an effect known as 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]. 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.

The era is known as reionisation because, after the Big Bang, matter formed first into protons and electrons. 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. This image, taken with the NASA/ESA Hubble Space Telescope, shows a massive galaxy cluster, about 4.6 billion light years away. 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 analogue of galaxies which existed at a much earlier time in the history of the Universe: a period known as the epoch of reionisation -- 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].
