The most distant star ever recorded is more than twice as hot as the Sun, about a million times more luminous

The farthest star ever detected, located behind what NASA describes as a “wrinkle in space-time,” is more than twice as hot as the Sun and about a million times brighter.

The James Webb Space Telescope has revealed new details about the dubbed star Arendelle, which was discovered by the Hubble Space Telescope last year. Earendel, part of the Sunrise Arc galaxy, can only be detected because the galactic cluster is so massive that it Space texture wraps, producing a magnifying effect through which astronomers can look, according to NASA. In the months since the discovery of Eärendel, Webb has spotted other very distant stars, though none are as far away as Eäerndel.

“The discoveries have opened up a whole new realm of universe for stellar physics, and a new topic for scientists studying the early universe, where galaxies were once the smallest cosmic bodies detectable,” NASA said. “The research team has a cautious hope that this is a step toward the eventual discovery of one of the first generation of stars, consisting solely of the primordial components of the universe that arose in the Big Bang – hydrogen and helium.”

Earendel is located along a wrinkle in space-time which gives it extreme magnification.

Scientists said that because of Eärendel’s distance from Earth, its light took 12.9 billion years to reach us. The universe was less than a billion years old when the light was emitted. The star is now 28 billion light-years away.

Based on the colors observed with Webb, astronomers think Earendel, which means “morning star” or “rising light” in Old English, may have a cooler, redder companion star as well.

Hubble observed the oldest and most distant single star in 2018. The light from this star, called Icarus, took 9 billion years to reach Earth, according to NASA.

Victoria Strait, co-author of the preliminary study on Earendel, said earlier that the ancient star offers scientists an opportunity to learn more about the past.

“As we study the universe, we also look back in time, so these very high-resolution observations allow us to understand the building blocks of some of the very first galaxies,” previously said.
