On s'est trompés sur le BIG BANG (James Webb relance TOUT)

A telescope is a time machine. Since light takes time to reach us, observing space is like looking into the past. The farther a telescope can see, the more it allows us to glimpse phenomena that occurred billions of years ago, at the very beginning of the universe. This is precisely what the James Webb Telescope allows, designed with extreme optimization to capture infrared light from the far reaches of the cosmos. Thanks to it, astronomers have been able to observe galaxies much older, more massive, and more structured than our models predicted. And these discoveries have profoundly changed our understanding of the universe, opening the door to new questions about its origins and evolution. ______________________ 🌌 CONTINUE EXPLORING Want to delve deeper into the subject?
