Post navigation The James Webb Space Telescope (JWST) has recently identified the largest known galaxy cluster in the early universe. It contains more than 400 trillion stars and is 13.2 billion light years away from Earth. This cluster is twice as heavy as the next most massive distant galaxy cluster known. Russian and Chinese naval vessels conducted drills in the waters near Alaska in August 2020. This alarmed US defense officials, who saw the joint operation as a potential challenge to the US presence. As a result of this event, the US is now considering how it will patrol and protect its Arctic borders.
