A recent study has determined the cosmic age of a very far-off galaxy under the direction of a collaborative team from Nagoya University and the National Astronomical Observatory of Japan. The scientists discovered a radio signal that has been traveling for around 97% of the universe’s lifetime using the ALMA radio telescope array. The James Webb Space Telescope’s discovery of galaxies in the very early Universe is now confirmed by this finding. Monthly Notices of the Royal Astronomical Society is where the study is published.

The group discovered a radio signal using the ALMA radio telescope array it has been moving for almost 97% of the time the universe has existed.

The galaxy, known as GHZ2/GLASS-z12, was first discovered in the JWST GLASS survey, which scans the far reaches of the Universe including the regions in the shadow of giant galaxy clusters. These observations are made up of a number of photographs taken using various broad-band color filters, which are comparable to the distinct RGB colors in a camera. Because it takes so long for the light from distant galaxies to reach us, the Universe’s expansion has caused this light’s color to shift toward the red end of the visible light spectrum, or what is known as redshift. So, it was easier for astronomers to recognize GHZ2/GLASS-z12 as one of the most persuasive possibilities for a distant galaxy they had detected due to its red color.
