Telescopic views reveal the spectacular cluster&#8217;s hundreds of thousands of stars. At a distance of 25,000 light-years, the cluster stars crowd into a region 150 light-years in diameter. Approaching the cluster core upwards of 100 stars could be contained in a cube just 3 light-years on a side. For comparison, the closest star to the Sun is over 4 light-years away. Along with the cluster&#8217;s dense core, the outer reaches of M13 are highlighted in this sharp color image. The cluster&#8217;s evolved red and blue giant stars show up in yellowish and blue tints. via NASA <a href=\"http:\/\/ift.tt\/2qVE9iG\"><\/a><\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>In 1716, English astronomer Edmond Halley noted, &#8220;This is but a little Patch, but it shews itself to the naked Eye, when the Sky is serene and the Moon absent.&#8221; <a href=\"http:\/\/finn-family.com\/?p=6589\" class=\"more-link\">[&hellip;]<\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"Layout":"","footnotes":"","_links_to":"","_links_to_target":""},"categories":[9],"tags":[10,12],"class_list":["entry","author-admin","post-6589","post","type-post","status-publish","format-standard","category-whatsup","tag-ifttt","tag-nasa"],"jetpack_sharing_enabled":true,"jetpack_featured_media_url":"","_links":{"self":[{"href":"http:\/\/finn-family.com\/index.php?rest_route=\/wp\/v2\/posts\/6589","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/finn-family.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/finn-family.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/finn-family.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/finn-family.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=6589"}],"version-history":[{"count":1,"href":"http:\/\/finn-family.com\/index.php?rest_route=\/wp\/v2\/posts\/6589\/revisions"}],"predecessor-version":[{"id":6590,"href":"http:\/\/finn-family.com\/index.php?rest_route=\/wp\/v2\/posts\/6589\/revisions\/6590"}],"wp:attachment":[{"href":"http:\/\/finn-family.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=6589"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/finn-family.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=6589"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/finn-family.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=6589"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
