Traveled through space billions of years in the past and captured images of quasars like never before.
Theo BGR, James Webb has done the craziest things since he began his journey to conquer the universe. The latest telescope not only took many amazing images of the universe, but also recently traveled 11.5 billion years into the past to see it. “rainbow knot – rainbow knot”.
Recently, astronomers looked even further into the past with Webb, when they discovered starlight from some quasar (quasars – ultra-bright and ultra-bright galaxies) are the oldest dating humans have ever seen.
TWO ancient galaxies are seen in their primordial state when the universe was less than a billion years old. The current universe is estimated to be around 13.8 billion years old, so James Webb’s new discovery has brought back an image of one of the oldest galaxies astronomers have observed to date. Astronomers say light from these two galaxies takes 12.9 and 12.8 billion years to reach Earth.

Quasars over 12 billion years old have just been discovered by James Webb.
Observations of these two ancient quasars reveal that their masses are 130 billion and 30 billion times the mass of the Sun, respectively, and the masses of the black holes inside these galaxies are also greater than 1.4 billion times and 200 million times. the mass of the Sun.
This information not only sheds light on the first galaxies, but also shows that the masses of these galaxies and their black holes are similar to what astronomers have seen in astronomical observations of another nearby.
Astronomers consider some of the most extreme features in the universe. These entities are powered by supermassive black holes surrounded by dust and gas, much of which is condensed into the black holes at the center of the galaxies in which they reside. Quasars are generally known for their exceptionally bright light.
Why quasars form is still a mystery. However, James Webb’s new discovery has helped mankind better understand ancient quasars and how far they can be found from Earth, which is of great interest to those trying to unravel the mysteries of the early universe.
