NASA’s Edwin Powell Hubble telescope has smashed records by observing the farthest individual star ever seen, detecting light from a star that took 12.9 billion years to reach Earth.
Nicknamed “Earendel,” this fresh detected star emitted its light throughout the primary billion years of our universe when the universe was seven % of its current age, at redshift 6.2, per NASA. Astronomers use redshifts to measure how the universe is expanding. How far away the distance an object is from Earth by looking at the “shift” in wavelengths.
Earendel, which suggests “morning star” in the English language, had become the foremost distant individual star ever to be seen by quite a significant margin because the previous single-star record holder, detected by Hubble in 2018, existed when the universe was about four billion years ago, or thirty % of its current age, at redshift 1.5, with its light taking nine billion years to reach Earth.
NASA shared an associate annotated view of Earendel’s position along “a ripple in space-time (dotted line) that magnifies it and makes it possible for the star to be detected over such a distant distance.” There was an enormous galaxy cluster sitting between the star and Earth that created a strong natural magnifying glass for the celestial objects behind it.
Having examined the star, the research team estimated that Earendel is a minimum of fifty times the mass of our sun and millions of times as bright, revealing the well-known huge stars. For comparison functions, its value notes that the mass of the sun is 1.989 x 1030 kilograms, that estimates to be estimated 333,000 times the mass of the Earth.
