NASA’s James Webb Space Telescope has captured an image of the most distant star known as ‘Earendel’. Utilizing the gravitational lensing technique, this breakthrough offers profound insights into the early universe and its initial stars.

The James Webb Space Telescope, in parallel to the legacy of the renowned Hubble Space Telescope, has focused its gaze on the farthest star ever identified. Equipped with its specialized camera known as NIRCam, the telescope has unveiled Earendel as a super-hot and super-bright B-type star, surpassing the heat of the Sun.

Earendel is located in the Sunrise Arc galaxy and its visibility is made possible through the phenomenon of gravitational lensing. The massive galaxy cluster WHL0137-08 distorts space, making distant objects appear larger. Despite the distorted galaxy, Earendel stands out as a singular point of light. It is incredibly tiny, approximately 4,000 times smaller than our usual observable threshold. This makes it the most remote star ever detected, emerging just a billion years after the Big Bang.

The James Webb Space Telescope’s advanced camera also reveals the Sunrise Arc galaxy in intricate detail. It showcases young and mature stars as minute specks, offering scientists insights into star clusters in the Milky Way during its early stages.

Researchers are using Webb’s specialized camera to unravel the composition and distance of the Sunrise Arc galaxy. While other distant stars have been identified using this technique, Earendel stands out for its extreme remoteness. These discoveries open up new possibilities for astronomers to study the early universe and its first stellar inhabitants.
