James Webb showed maybe the oldest galaxy in the universe

On two new images of the James Web telescope, scientists discovered one of the earliest galaxies ever seen, both of which show objects over 13 billion years of age, as a result of the collaboration of NASA astronomers and global partners around the world.

A team of experts identified a particularly interesting object named Macy's galaxy after the daughter of the project manager Stephen Finkelstein, which scientists estimate appeared only 290 million years after the Big Bang.

Details of the galaxy have been published on the ArXiv preprint server and are awaiting publication in a peer-reviewed journal. If the discovery is confirmed, Macy will be one of the earliest galaxies ever seen, and it will also confirm that galaxies have begun to form much earlier than many astronomers thought.

The CEERS co-operation consists of 18 researchers from 12 institutions and more than 100 employees from the United States and nine other countries, who study how some of the earliest galaxies were formed when the age of the universe was less than 5 per cent of its current age; this period is known as reionization.
