The James Webb Space Telescope is a joint work between NASA, the United States and the European Space Agency. The Canadian Space Agency has revolutionized our understanding of the early universe. The latter has been in use since 2022, having discovered a variety of amazing objects and phenomena in space.
Recently, a team of astrophysicists from the Stuart Observatory of the University of Arizona in the United States and the Institute of Cosmology at the University of Cambridge in England released the results of a survey from the JWST Advanced Deep Extragalactic Survey-JADES project, which is considered to have shattered Another record was set with the James Webb Space Telescope: two galaxies were found: JADES-GS-z14-0 and JADES-GS-z14-1. It is located so far away that light from both galaxies reaches our planet. It comes from a time when the universe was only 290 million years old. These galaxies represent about 2% of the current age of the universe, calculated at 13.8 billion years, and will deepen astronomers' understanding of the early universe.
The galaxy with the oldest record ever is Gadis-GS-z13-0. It occurred 325 million years after the birth of the universe and has a diameter of about 1,700 light-years (a light-year is the distance light travels in one year, or 9.5 trillion kilometers). The galaxy has a mass equivalent to 500 million stars the size of our Sun and is actively forming stars. This galaxy is rapidly adding about 20 new stars per year, and is the oldest known galaxy at this time.
