Io is constantly being resurfaced by volcanoes. Europa has a giant liquid water ocean. And Ganymede has its own magnetic field that interacts with its parent planet in weird ways. Callisto, by comparison, seems sedate, with its ancient, crater-saturated surface seemingly frozen in time. But new data from the James Webb Space Telescope (JWST) shows that even this most benign of the Big Four moons is more active than previously realized.<\/div>\n<p><a href=\"https:\/\/phys.org\/news\/2026-08-jwst-peeks-callisto-ancient-scars.html\">Go to Source<\/a><br \/>\nAuthor: <\/p>\n<div>The latest science news on astronomy, astrobiology,  and space exploration from Phys.org.<\/div>\n<hr>\n<p>SPACEPERIUM CORPS &#038; RESEARCH CONTRIBUTORS<\/p>\n<hr>\n<p>Please comment below with research and links for fellow members to conduct further research into this area.<br \/>\nYou must be registered and signed into SPACEPERIUM BLOG in order to leave your comment and get credited!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>JWST peeks at Callisto&#8217;s ancient scars Of Jupiter&#8217;s four Galilean moons, Callisto is the one that gets the least attention&#8230;.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"registered_only","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[1],"tags":[],"_links":{"self":[{"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/posts\/3983"}],"collection":[{"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/comments?post=3983"}],"version-history":[{"count":0,"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/posts\/3983\/revisions"}],"wp:attachment":[{"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/media?parent=3983"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/categories?post=3983"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mycbh.com\/Games\/spaceperium\/wp-json\/wp\/v2\/tags?post=3983"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
