5 pictures to mark one year of the James Webb Space Telescope

By analysing new observations from NASA’s James Webb Space Telescope, a team led by Simon Lilly of ETH Zürich in Switzerland found evidence that galaxies that existed 900 million years after the big bang ionized the gas around them, causing it to become transparent.
