James Webb Space Telescope has returned to Earth after detecting the farthest star in an unexplored of our universe within the first billion years following the big bang, said by US space agency.
The Earendel star was first detected by the Hubble Space Telescope. Last year, it revealed by a James Webb Space telescope. According to NASA, Earendel is part of the Sunrise Arc galaxy. However, it is only detectable due to the cluster’s massive size. It causes space to expand, giving astronomers an unparalleled view. Since Earendel discovered, Webb has been lucky enough to other stars are far away.
The most remote star discovered on the Hubble telescope is named after Tolkien’s work.
Astronomers named it Earendel star, which is located in the Sunrise Arc galaxy, 12.9 billion light-years away. “NASA’s James Webb Space Telescope tracks Hubble Space Telescope observations of the most distant star ever discovered in the distant universe within the first billion years after the Big Bang.” The space agency announced on Tuesday.
Telescopes see the star thanks to the gravitational lensing that a massive nearby galaxy bends space-time and bends the path of light around it, making nearby objects visible.
Arendelle was visible because it was located behind the fold of space-time created by the galaxy cluster WHL0137-08. The cluster of galaxies between us and Arendelle is so massive that it distorts the structure of the universe itself. It creates a magnifying effect that allows astronomers to peer into the cluster. However, if through a magnifying glass.
In addition, new data also reveal that Earendel may have other stars nearby. Astronomers have studied the colors of Earendel to see if there are any nearby stars. Stars with Earendel’s mass often have companions.
Astronomers did not expect Webb to reveal Earendel’s companions because they are so close together in the sky. They are indistinguishable, NASA said.
