The property, known as the dielectric constant, is the ratio of the electric permeability of a material to the electric permeability of a vacuum.<\/p>\n<p>\u2022 The Mini-RF team observed that the level of this property increased as they surveyed larger craters, and kept rising in crater sizes up to 5 km in diameter. Beyond that size, the value of the dielectric constant levelled off.<\/p>\n<p>\u2022 The finding could aid in drawing a clearer connection between Earth and the Moon.<\/p>\n<p><b>The Moon formation hypothesis:<\/b><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/useruploads.socratic.org\/Io4vbbVShOBR6gQTkKcK_moon_formation.png\" alt=\"What do scientists hypothesize about how the moon formed? | Socratic\" \/><\/p>\n<p>\u2022 The most popular theory about the Moon\u2019s creation is that a Mars-sized protoplanet collided with newly formed Earth around 4.5 billion years ago, breaking off a piece of our planet that went on to become its satellite.<\/p>\n<p>\u2022 The hypothesis is also backed by substantial evidence, such as the close resemblance between the Moon\u2019s bulk chemical composition with that of Earth.<\/p>\n<p>\u2022 It is also known that Earth\u2019s crust has lesser amounts of iron oxide than the Moon\u2013 a finding that scientists have been trying to explain. Now, the new discovery of even greater quantities of metal on the Moon makes their job even more difficult.<\/p>\n<\/div>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #0000ff;\"><strong>For more such notes, Articles, News &amp; Views Join our Telegram Channel.<\/strong><\/span><\/p>\n<p><a title=\"Telegram Link\" href=\"https:\/\/t.me\/triumphias\" target=\"_blank\"><span style=\"color: #ff0000;\"><strong>https:\/\/t.me\/triumphias<\/strong><\/span><\/a><\/p>\n<p><span style=\"color: #0000ff;\"><strong>Click the link below to see the details about the UPSC \u2013Civils courses offered by Triumph IAS.<\/strong> <\/span><span style=\"color: #ff0000;\"><strong><a style=\"color: #ff0000;\" title=\"Courses available\" href=\"https:\/\/triumphias.com\/pages-all-courses.php\">https:\/\/triumphias.com\/pages-all-courses.php<\/a><\/strong><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Relevance: Prelims: Science and technology Why in news? \u2022 In a new milestone in lunar exploration, NASA said that it\u2019s<\/p>\n","protected":false},"author":1,"featured_media":6727,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[123],"tags":[392],"class_list":["post-8932","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-current-affairs","tag-union-public-service-commission-upsc"],"amp_enabled":true,"_links":{"self":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts\/8932","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/comments?post=8932"}],"version-history":[{"count":1,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts\/8932\/revisions"}],"predecessor-version":[{"id":8933,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/posts\/8932\/revisions\/8933"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/media\/6727"}],"wp:attachment":[{"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/media?parent=8932"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/categories?post=8932"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/triumphias.com\/blog\/wp-json\/wp\/v2\/tags?post=8932"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
