The Hubble Space Telescope has detected a distant star never seen before

The Hubble Space Telescope observed an unprecedented distance star, and it was called “Erendel” because its light took 12.9 billion years to reach Earth.

Scientists estimate that the size of the star competing with the largest known stars is at least fifty times greater than that of the Sun, and it is millions of times brighter.

As for the previous star, it set records, it was tracked by the Hubble telescope in 2018, but it was in the universe four billion years ago, only about 900 million years after “Erdel” after the Big Bang. According to experts.

The discovery was published Wednesday in the prestigious scientific journal Nature.

Brian Welch, a leading reporting editor at Johns Hopkins University in Baltimore, said in a statement that “we did not initially believe the telescope’s.

Welch took on the task of naming the star and named it “Erindl”, meaning “Morning Star” in Old English.

The researcher explained that this star “has been around for so long that it could not have been made of objects like the stars around us today.”

He added, “Studying this star will open the way for us to learn more about a particular time period in the universe, but it has led to everything we know today.”

So this star will be the main target of the new “James Webb” space telescope, whose capabilities are currently being tested in space. The European Space Agency, which operates the telescope in conjunction with US space agency NASA, has said James Webb will monitor Erendle from this year onwards.

Like the sound that disappears when an object moves away, the wave of light expands and travels from the apparent frequency to the naked eye and then to infrared radiation.
Unlike the Hubble, which has the simple ability to capture infrared radiation, James Webb focuses on light waves, which help detect objects at greater distances.

To date, only groups of stars are found at these distances, especially without the possibility of detecting a star.

But the new star benefited from a cosmic aid represented by an event called gravitational lensing, a group of galaxies located between us and the star that acts as a magnifying glass to amplify the light of the body.

The European Space Agency compared this effect to ripples on the surface of the water, which in good weather emit extended beams of light to the floor of the swimming pool.

Astronomers say this rare alignment will continue in the coming years.
