The Webb telescope showed the most distant star in the universe

The James Webb Space Telescope photographed the most distant star in the universe. She was named Earendel, writes Space. Scientists suggest that it is twice as hot as the Sun, and probably has a stellar companion. Astronomers discovered Earendel in 2022 using the Hubble telescope.

It took 12.9 billion years for Eärendel’s light to reach Earth. However, the universe expanded at an accelerated rate after the Big Bang, so the most distant star is located 28 billion light years from Earth. Hubble was able to spot Earendel thanks to a phenomenon known as gravitational lensing. Scientists have established that a massive body bends the direction of radiation propagation with its gravitational field, just as a light beam is bent by an ordinary lens. So Hubble used the same strategy, exploiting the space-warping force of the gravitational cluster WHL0137-08. Earendel in projection NASA astronomers also suggest that Earendel has a cold, red companion star. “This light has been stretched by the expansion of the universe to wavelengths longer than Hubble’s instruments can detect, and therefore could only be detected by Webb,” they said.
