The James Webb Space Telescope (JWST) has potentially smashed one of its own records again, potentially spotting the earliest and most distant galaxies ever seen. The five candidate galaxies are so distant that the powerful space telescope sees them as they were just 200 million years after the...
JAMES WEBB SPACE TELESCOPE: FIRST LIGHT MACHINE Imagine a time machine so powerful that you could peer back 13.5 billion years into the past to witness the ‘birth’ of the universe and watch as the greatest origin story of all unfolds. The James Webb Space Telescope (JWST), fondly referred...
