International research groups such as Chiba University have announced that they have succeeded in observing the farthest star, 12.9 billion light-years away from the Earth, and it is expected to be a clue to the state of the early universe. ..
International research groups such as Chiba University and Johns Hopkins University in the United States have announced that they have used the Hubble Space Telescope to discover a star 12.9 billion light-years away from Earth.
One star is about 4 billion light-years further away than the most distantly observed star so far.
The research group found that gravity acted like a lens, allowing us to observe a single star in the galaxy, which weighs at least 50 times the weight of the Sun. It is said that.
This star was created 900 million years after the birth of the universe, 12.9 billion years ago, from the distance to the earth, and is expected to be a clue to the evolution of the stars in the early universe.
Makoto Oguri, a professor at Chiba University who participated in the research group, said, "Although more than 13 billion light-years have been found in the galaxy, it is the farthest star. I want to investigate the temperature and clarify how stars are created in the early universe. "
