It takes time to recover from the enormity of it.”<\/p>\n 6<\/p>\n This is what the ocean world of K2-18b might look like if you were taking a dip in its vast seasCredit: Amanda Smith 6<\/p>\n![\"NASA's](\"https:\/\/www.europesays.com\/uk\/wp-content\/uploads\/2025\/04\/s-left-scientists-stumped-nasa-988586079.jpg\")
