Earth\u2019s orbit allowed for <a href=\"http:\/\/www.uncommongoods.pro\/product\/adventure-filter-water-bottle\" target=\"_blank\">abundant liquid water<\/a>, a key ingredient for the development of life as we know it. Showing their whimsical side, those 70s scientists named this habitable zone the \u201cGoldilocks Zone,\u201d <a href=\"http:\/\/www.dltk-teach.com\/rhymes\/goldilocks_story.htm\" target=\"_blank\">after the little girl who sampled the three bears\u2019 porridge and settled on the bowl that was just right. <\/a>Officially, this sweet spot of planetary hospitality is called the <a href=\"http:\/\/astro.unl.edu\/naap\/habitablezones\/chz.html\" target=\"_blank\">Circumstellar Habitable Zone<\/a>, or CHZ, but Goldilocks provided a cuter and more memorable nickname.<\/p>\n<p><a href=\"http:\/\/planetquest.jpl.nasa.gov\/page\/history\" target=\"_blank\">Now that the discovery of exoplanets is in full swing<\/a>, worlds in the Goldilocks Zone of other stars tend to get the most publicity, as they\u2019re most likely to support extraterrestrial life, whether its alien bacteria or little green men. Meanwhile, discoveries here on Earth have us re-thinking the boundaries of the Goldilocks Zone itself. From <a href=\"http:\/\/www.arctic.noaa.gov\/essay_krembsdeming.html\" target=\"_blank\">microbes that flourish under Arctic ice<\/a> to <a href=\"http:\/\/ocean.si.edu\/ocean-videos\/hydrothermal-vent-creatures\" target=\"_blank\">organisms that hang out in the scalding hot, total darkness around ocean floor volcanic vents<\/a>, life can exist in places that finicky Goldilocks would have avoided altogether. For that matter, a tiny \u201cbear\u201d has got them all beat: the <a href=\"https:\/\/www.youtube.com\/watch?v=cjV2WP0wkvo\" target=\"_blank\">tardigrade, or \u201cwater bear.\u201d<\/a><a href=\"http:\/\/tvblogs.nationalgeographic.com\/2014\/03\/19\/5-reasons-why-the-tardigrade-is-natures-toughest-animal\/\" target=\"_blank\"> Along with surviving in solid ice or boiling water, tardigrades can tolerate cosmic rays and the vacuum of space<\/a>\u2014conditions way outside of Goldilocks\u2019 comfort zone. These tough little troopers prove that life is far more tolerant than the three bears\u2019 high-maintenance home invader.<\/p>\n<p><a href=\"http:\/\/www.uncommongoods.pro\/product\/a-new-day?source=blog_UK_20150817\" target=\"_blank\">A New Day<\/a> | $40.00<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Back in the 1970s, when the search for planets outside our solar system (exoplanets) was little more than a fairy tale, astronomers surmised that Earth was the only spot in our stellar neighborhood where conditions were conducive to life.<\/p>\n","protected":false},"author":144,"featured_media":39374,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1208],"tags":[1511,813],"_links":{"self":[{"href":"https:\/\/www.uncommongoods.pro\/blog\/wp-json\/wp\/v2\/posts\/38827"}],"collection":[{"href":"https:\/\/www.uncommongoods.pro\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.uncommongoods.pro\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.uncommongoods.pro\/blog\/wp-json\/wp\/v2\/users\/144"}],"replies":[{"embeddable":true,"href":"https:\/\/www.uncommongoods.pro\/blog\/wp-json\/wp\/v2\/comments?post=38827"}],"version-history":[{"count":4,"href":"https:\/\/www.uncommongoods.pro\/blog\/wp-json\/wp\/v2\/posts\/38827\/revisions"}],"predecessor-version":[{"id":39373,"href":"https:\/\/www.uncommongoods.pro\/blog\/wp-json\/wp\/v2\/posts\/38827\/revisions\/39373"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.uncommongoods.pro\/blog\/wp-json\/wp\/v2\/media\/39374"}],"wp:attachment":[{"href":"https:\/\/www.uncommongoods.pro\/blog\/wp-json\/wp\/v2\/media?parent=38827"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.uncommongoods.pro\/blog\/wp-json\/wp\/v2\/categories?post=38827"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.uncommongoods.pro\/blog\/wp-json\/wp\/v2\/tags?post=38827"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
