The James Webb Space Telescope has taken the first image of the most distant known star in the universe.

Named Earendel, after a character in J. R. R. Tolkien’s prequel The Lord of the Rings, The Silmarillion, it lies almost 28 billion light-years from Earth.

That’s over 10 billion light-years further than the next most distant star astronomers have ever seen.

At such vast distances, experts can usually only see entire galaxies, but a happy coincidence allowed them to detect Earendel with the Hubble Space Telescope, and then observe it again with Webb on July 30th.

By comparing the Hubble image to that taken by NASA’s new $10 billion (£7.4 billion) Super Space Telescope, experts were able to find the elusive Earendel as a faint red dot under a cluster of distant galaxies.

WHAT IS GRAVITATIONAL LENSING?

Gravitational lensing occurs when a massive galaxy or cluster of galaxies bends the light emitted by a more distant galaxy.

This produces a highly magnified, albeit highly distorted, image.

This is because massive objects bend space-time around them, causing light to take a different path.

This theory was first proposed by Einstein in his general theory of relativity.

The star, whose light has traveled 12.9 billion light-years from Earth, is so dim it would be hard to find without the help of Hubble, which maps visible ultraviolet light to Webb’s infrared light.

This example of two telescopes working side by side is exactly what NASA envisioned, despite Webb being ultimately seen as the successor to the famous Hubble.

“We are pleased to share the first JWST image of Earendel, the most distant star known in our Universe, with a lens and magnification of a massive galaxy cluster,” the team of astronomers said using the Cosmic Spring JWST Twitter account.

Their tweet refers to gravitational lensing, where light is stretched into a long curve by the gravity of a cluster of galaxies closer to Earth.

This process enlarged the Sunrise Arc galaxy that houses Earendel by more than 1,000 times, allowing astronomers to confirm with Webb that it is a single star and not a cluster of hundreds.

The star is visible, experts say, because it is perfectly aligned with the cluster of galaxies to provide the highest magnification possible.

“It’s a really lucky coincidence,” said Dan Coe of the Space Telescope Science Institute in Maryland. New scientist.

“No one has ever seen a star at such a high magnification, let alone a galaxy.”

Because light takes time to travel, this new Webb image shows Earendel about 900 million years after the Big Bang.

According to Brian Welch, Ph.D., who led a team of astronomers at Johns Hopkins University in the discovery of a distant star, Tolkien’s character Earendil was the inspiration for Earendel’s name.

“Once we were fairly certain that this object was a star, I started coming up with possible names,” he said.

“Eärendil was one of the first things that came to mind, as he eventually sails his ship Vingilot through the heavens with the Silmaril on his forehead, becoming a star and a symbol of hope over Middle-earth.

“If I looked into it further, I found that Tolkien’s original inspiration for the character was the Old English word Earendel, meaning Morning Star.”

Welch added, “The ‘morning star’ reference worked particularly well, as this time period is often referred to as the Cosmic Dawn, so that was the deciding factor for me.”

At such vast distances, experts can usually only see entire galaxies, but a happy coincidence allowed them to spot Earendel with the Hubble Space Telescope (pictured) and then observe it again with James Webb on July 30.

“JWST was designed to study the first stars. Until recently, we assumed that this meant populations of stars in the first galaxies,” astronomers from the Space Telescope Science Institute in Maryland wrote in a recent paper on gravitational lensing.

“But in the past three years, three separate stars with strong lenses have been discovered.

“This provides new hope for the direct observation of individual stars at cosmological distances with the JWST.”

Astronomers are hoping that the next round of Webb observations for the Space Telescope Science Institute team, scheduled for December, could show what Earendel and the sunrise arc are made of.

“We are all made of stellar stuff, but that stuff didn’t exist in the early universe,” Coe said.

“This is a rare opportunity to see if there were heavy elements in this star 13 billion years ago.”

Last month, the world was first shown Webb’s dazzling, unprecedented images of the “stellar nursery,” a dying star shrouded in dust, and a “cosmic dance” between a group of galaxies.

It ended months of anticipation and feverish anticipation as people around the world saw the first batch of a treasure trove of images culminating in the earliest look at the dawn of the universe.

Webb’s infrared capabilities mean it can “look back” to 100 to 200 million years after the Big Bang, allowing it to capture the very first stars that shone in the universe more than 13.5 billion years ago.

His first images of nebulae, exoplanets and clusters of galaxies caused a huge celebration in the scientific world, which was hailed as “a great day for mankind.”

Researchers will soon begin to learn more about the masses, ages, history and composition of galaxies as Webb aims to explore the earliest galaxies in the universe.

James Webb Telescope: NASA’s $10 billion telescope is designed to detect light from the earliest stars and galaxies.

The James Webb Telescope has been called a “time machine” that can help unravel the mysteries of our universe.

The telescope will be used to look back at the first galaxies born in the early universe more than 13.5 billion years ago and observe the sources of stars, exoplanets and even our solar system’s moons and planets.

Already worth over $7 billion (£5 billion), the Fast Telescope is said to be the successor to the Hubble Orbiting Space Telescope.

The James Webb telescope and most of his instruments have an operating temperature of approximately 40 Kelvin – about minus 387 Fahrenheit (minus 233 Celsius).

It is the world’s largest and most powerful orbiting space telescope, capable of seeing 100-200 million years ago after the Big Bang.

The Orbital Infrared Observatory is designed to be about 100 times more powerful than its predecessor, the Hubble Space Telescope.

NASA prefers to think of James Webb as Hubble’s successor rather than his replacement, as the two will work in tandem for a while.

The Hubble Telescope was launched on April 24, 1990 by the Space Shuttle Discovery from the Kennedy Space Center in Florida.

It orbits the Earth at about 17,000 miles per hour (27,300 km per hour) in low Earth orbit at an altitude of about 340 miles.
