The most distant star ever seen is nearly 28 billion light years away. A lucky coincidence allowed researchers to spot Earendel with the Hubble Space Telescope and then observe it again on July 30th.

Earendel is a star located in the Sunrise Arc. The light has been stretched into a curve by the gravity of a cluster closer to Earth. Astronomers were able to confirm that Earendel is an individual star with the help of this process.

Earendel is perfectly aligned with the galaxy cluster to give us the best magnification. Dan Coe is a member of the team that made the new measurement. Nobody has ever seen a star this large. Earendel is more distant than the next-furthest star.

Earendel is now being observed because light takes time to travel. Stars in the early universe are expected to have different chemical compositions due to the fact that heavier elements were formed over time in supernovae.

Earendel and the Sunrise Arc will be revealed in the next round of observations. Coe says that star stuff wasn't around in the early universe. It's a rare chance to see if the heavy elements were present 13 billion years ago.
