hey James Webb Space Telescope (JWST)gives NASAOldest known galaxy found in Universe, The collection of stars, called GLASS-z1, dates back to 300 million years after the Big Bang. It overtakes the previous oldest galaxy, GN-Z11, which was detected Hubble Space Telescope With an “age” of 100 million years.
Researchers at Harvard and the Smithsonian Center for Astrophysics in Massachusetts have also discovered a second galaxy called GLASS-z11, which is about the same age as reported Guardian,
Both galaxies have a mass equal to one billion Suns, which may indicate an earlier date of origin by 500 million years. They are relatively small compared to the Milky Way, which is 100,000 light-years across. For example, Glass Z-11 is 2300 light years away.
“If these galaxies are at a distance from what we think, then the universe is only a few hundred million years old,” says Rohan Naidu, a graduate student at the university.
All the Chips on James Webb
It is possible that James Webb may be able to look further back and discover galaxies that are only 200 million years old. This will be an important step in JWST’s mission to create a cosmic map.
The discoveries of James Webb are being celebrated by the scientific community. Last week, NASA released First pictures recorded by telescopeThat includes the Carina Nebula, a collection of galaxies known as “Stephen’s Quintet”, and a spectrum of light from the exoplanet WASP-96b.
