A new study led by a joint team at Nagoya University and the National Astronomical Observatory of Japan has measured the cosmic age of a very distant galaxy. The team used the ALMA radio telescope array to detect a radio signal that has been traveling for approximately 97% of the age of the universe. This discovery confirms the existence of galaxies in the very early universe found by the James Webb Space Telescope. The research is published in Monthly Notices of the Royal Astronomical Society.
