The team needed a new approach. So the researchers custom-built a diffraction grating array -- a square of silicon about the size of a pencil eraser's head and scored with tiny lines. These lines ...

Astronomers have discovered the most distant and thus earliest spiral galaxy ever seen, using the James Webb Space Telescope (JWST). This "twin" of the Milky Way existed just 1 billion years after ...

The discovery was made using data from the James Webb Space Telescope (JWST) and offers important insights into how galaxies can form and evolve so rapidly in the early Universe. An international ...

A. Oesch (University of Geneva), G. Brammer (Niels Bohr Institute) When astronomers used the James Webb Space Telescope (JWST) to peer deep into the early universe, they made a serendipitous ...

Look alive: The James Webb Space Telescope (JWST) may have picked up signs of a potential biosignature on a steamy, ocean-covered exoplanet called K2-18b—a biosignature that, on Earth ...

However, the JWST is beginning to reveal a very different picture. Its deep infrared imaging is uncovering surprisingly massive and well-structured galaxies at much earlier times than previously ...
