NASA / ESA Hubble Space Telescope has launched a new model: detecting the light of a star that lived in the first billions of years after the Universe was born in the Big Bang (at a red light of 6.2 ) – the single farthest star seen. . This sets a major goal for the NASA / ESA / CSA James Webb Space Telescope in its first year.
This information is a huge leap when compared to the previous one -star recorder; Discovered by Hubble in 2018. That star lived during the entire universe for about 4 billion years, or 30 percent of its current age, at the time the stars are called “redshift 1.5.” Scientists use the term “redshift” because as the universe expands, light is extended from distant distances or “converted” to reddish -brown lengths when it comes to us.
But the newly -seen star is so far away that its light took 12.9 billion years to reach Earth, which we see as it did when the universe was only 7 percent of its light. years now, in redshift 6.2. The smallest objects that can be seen in the distance are constellations, which are embedded in the first stars.
Thanks to its incompatibility with the magnifying glass galaxy, the star Earendel can be seen at, or very close to, a ripple in the fabric of the sky. This ripple, seen in optics as “caustic,” provides amplification and illumination. The effect simulates the surface of the swimming pool creating reflections of the glowing light under the lake in the sunlight. The waves on the skin are lenses that reflect the sun as a bright light on the water floor.
This kind of evil brings the star Earendel out of the bright light of his home galaxy. Its brightness was increased to a thousand or more. Currently astronomers cannot determine if Earendel is a binary star, but most major stars are smaller companion stars.
Astronomers expect that Earendel will be significantly expanded for years to come. It will be seen by the NASA / ESA / CSA James Webb Space Telescope later in 2022. Webb’s advanced knowledge of infrared light is necessary to learn more about Earth, because his light (redshifted) in long infrared waves through the expansion of the Universe.
