NASA’s James Webb Space Telescope has followed the lead of the Hubble Space Troscope in examining Earendel, the farthest star known to have been detected using the spacecraft.
A star that is hotter than the Sun.
Earendel is located in the Sunrise Arc galaxy, which is only visible through gravitational lensing due to a combination of nature and technology. This technique works best for long-distance telescopes. Webb was able to observe EAREndel thanks to WHL0137-08, whose massive rotation around space causes far-off objects to appear larger.
Due to the bending of the galaxy, most parts of it appear as clones, but Earendel appears as just one point of light. Scientists have discovered that EAREndel is extremely small, about 4,000 times smaller than we could normally see, which means it is the farthest star known to date, having been found just a billion years after the Big Bang.
Gravitation: How is it possible to use gravitational lensing?
The size of Earendel suggests the existence of a buddy star, which Webb could detect because it extended the light to nuances that Hubble couldn’t perceive.
Webb’s awe-inspiring camera captured the Sunrise Arc galaxy, the most magnified baby galaxy ever observed, with young and old stars appearing as tiny dots. Earendel is located in the middle of this galaxy to provide early insights into star clusters in our own Milky Way from an early date.
The study of Earendel and the Sunrise Arc continues, as astronomers continue to use Webb’s unique camera to gain insight into the galaxy’ composition and distance. He discovered several other far-off stars using this method, but none as distant as EAREndel. These discoveries are like opening up a new window in the universe for scientists who want to explore the early universe and its baby stars. The team hopes that this will allow them to spot the first hydrogen and helium made from the fundamental elements of the cosmos.
