Astronomers using the James Webb Space Telescope have detected the four oldest galaxies in the known universe, which are forming stars much faster than thought possible.
Astronomers using the James Webb Space Telescope have just discovered the four most distant galaxies ever seen, located a little over 13 billion light-years from Earth. This means astronomers are seeing what galaxies looked like only 300 to 500 million years after the Big Bang, in the infancy of our now almost 14 billion-year-old universe, according to two new studies published April 4 in the journal Nature Astronomy.
