From dead galaxies to mysterious red dots, here’s what the James Webb telescope discovered in just three years
Three years ago on this day, we witnessed the spectacular launch of the James Webb Space Telescope (JWST), the largest and most powerful telescope ever sent into space. It took 30 years to build, but in just three years of operation, JWST has already revolutionized our view of the universe. We’ve explored our own solar system, studied the atmospheres of…
