The final moment image of the star died

Thanks to new technology, American astronomers discovered two super-large explosions of stars at the edge of the universe. They are the farthest stars that humans have ever known.

Light from two explosions began to travel to Earth 11 billion years ago, not long after the universe was born by the Big Bang.

The supernova occurs when a star has 50 times the mass of the sun itself destroys by exploding. Often scientists discover supernova by capturing an aerospace space at various times and then comparing the pictures together. If they see a new light in a certain image, it is an explosion. The most distant star found by astronomers by technology is 6 billion light-years from Earth.

The latest imaging technique allows scientists to combine photos taken in a year and compare them with photos from many other years.

Dr. Jeff Cooke, an astronomer from the University of California (USA), explains: " If you put the whole image in one place, you can go deeper into the universe and discover faint objects that were previously We can't see it. This technique is like opening a shutter for a long time when taking photos to get more light . "

After analyzing thousands of photos provided by a telescope in Hawaii (USA), Cooke and his colleagues discovered four super-large explosions, including two at the edge of the universe.

" The universe has existed for about 13.7 billion years. So we can say we are looking at two of the first stars of the universe," Cooke said.

Last year Cooke and some astronomers discovered a group of galaxies 11.4 billion light-years from Earth. Those are the farthest galaxies that humans have ever found.
