13.3 billion years of cosmic history shrinked in this picture

Scientists synthesized nearly 7,500 images from the Hubble telescope in 16 years of operation to create an image that contains nearly 13.3 billion years of the entire universe.

The " stars" in the photo have just been published by the group of experts from the Hubble Legacy Field project is actually the image of nearly 265,000 galaxies from the milestone 500 million years after the Big Bang so far, according to CNN. .

The photo is the result of a collection of 7,500 photos collected by the US National Aeronautics and Space Agency (NASA) and the European Space Agency (ESA) for 16 years of operating the Hubble telescope. These images were gathered from 31 research groups and took 250 days to complete, according to CBC.

The original composite image has a resolution of up to 25500 x 25500 and a file size of more than 1.19 GB, posted on Hubble Site. Scientists can rely on a composite image to analyze the expansion of the universe and dead galaxies in the early stages of the universe, about 500 million years after the Big Bang.

"Hubble observes this area of ​​the sky many times over the years. We gathered all the captured images into a high-resolution photo with a wide viewing angle. This is like we have. a historical book about the universe in a single picture , "said Pieter van Dokkum, professor of astronomy at Yale University and a member of the image synthesis group.

Scientists say the Hubble Legacy Field image serves as a historical book because looking at the universe is synonymous with "looking at" time, when the light of stars and galaxies moves away. Thousands of years for us to see.

The image "collapses" some galaxies into bright dots because the image only shows about 1/10 billion of their actual brightness level. Those bright dots are the most distant galaxy and the human eye can only be observed at this level when there is no telescope.

This integrated project has 100 times more galaxies than previous deep-space surveys. Scientists describe this as the most comprehensive "portrait" to date of the universe.

"This image contains the entire history of the evolution of galaxies in the universe, from the" newborn "stage to the" mature "stage. There will be no photos beyond this project. until future generations of space telescopes were put into action, " said Garth Illingworth, head of visual synthesis at the University of California - Santa Cruz.

One of the next generation telescopes is the James Webbs telescope, which is expected to be launched into space in the early 2020s. Scientists believe the project could record the first galaxies created. after the Big Bang.
