The China Jinping Underground Laboratory (CJPL), now upgraded to CJPL-II, has begun operations in its quest to study dark matter, the mysterious substance that makes up over 80 percent of the universe's matter. Located 2,400 meters underground beneath Jinping Mountain, the facility aims to shield itself from cosmic rays and background noise to gather accurate dark matter data.
