James Webb Space Telescope Spots ‘The Coldest Ice in the Universe’ – Gigazen

On April 4, 2023, an academic journal specializing in astronomy, astrophysics, etc.natural astronomyThe James Webb Space Telescope has discovered the four most distant galaxies ever observed, one of which formed at the beginning of the universe just 320 million years after the Big Bang. It was reported.

The discovery of these galaxies was reported by NASA on December 9, 2022, before peer review of the paper. This time, with the paper being published in a peer-reviewed academic journal, the James Webb Space TelescopenirkamdevelopedSmellThe results of the study will be officially recognized.

The oldest ‘galaxy 13.4 billion years old’ in observational history can apparently be imaged with the James Webb Space Telescope – Gigazen

astronomerred offsetIt measures how far apart the galaxies are using a scale called. The higher the redshift value, the farther the celestial body is from Earth, and in the images taken with the NIRCam of the James Webb Space Telescope this time, the redshift is “13.20”, “12.63”, “11.58” and “10.38” observed galaxies. The galaxy named “JADES-GS-z13-0” with a redshift of “13.20” is said to be the most distant galaxy in the history of observation, about 13 billion light-years from Earth.

In addition, these galaxies are said to have been born only 300 to 500 million years after the Big Bang that occurred about 13.8 billion years ago, and are said to have formed. When these galaxies were born, the strong light of the stars stripped electrons from hydrogen and helium, ionizing the surrounding gas.Cosmic reionization“He thinks it has happened.

‘The four galaxies discovered this time have very low mass,’ said research team Stephen Charlotte. According to Charlotte, the number of these galaxies is about 100 million.solar massIt is said that the weight of the solar system belongs on the one handMilky WayIts mass is 1.5 trillion solar masses.

But these galaxies are thought to be forming stars at about the same rate as the Milky Way, which Charlotte says is “surprisingly fast for a galaxy in the early Universe.”

Also, when did these galaxies form?heavy itemThe galaxy discovered this time is said to be composed of simple elements such as hydrogen and helium atoms.
