The explosion was observed by Danish astronomer Tycho Brahe in 1572. The ejected matter from the explosion has expanded to fill a sphere 55 light-years across. In the image, low-energy X-rays are shown in red, illustrating the expanding debris from the supernova explosion, and blue high-energy X-rays show the blast wave \u2014 a shell of extremely energetic electrons. Type Ia supernovas, which originate from <a href=\"http:\/\/en.wikipedia.org\/wiki\/White_dwarf\">white dwarfs<\/a>, play an important role in measuring the universe, as they are bright enough to be seen across large distances and bright enough to act as a standard candle \u2014 the basic unit of luminous intensity. They were also used to discover the existence of dark energy.<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A 400-year-old supernova explosion creates a spectacular scene.<\/p>\n","protected":false},"author":13,"featured_media":5361,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[102,101,38,27],"tags":[284,856,72,155],"class_list":["post-5359","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-amazing-images","category-bulls-eye","category-nasa","category-space","tag-amazing-images-2","tag-bulls-eye","tag-nasa-2","tag-space-2"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/posts\/5359"}],"collection":[{"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/users\/13"}],"replies":[{"embeddable":true,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/comments?post=5359"}],"version-history":[{"count":3,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/posts\/5359\/revisions"}],"predecessor-version":[{"id":5410,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/posts\/5359\/revisions\/5410"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/media\/5361"}],"wp:attachment":[{"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/media?parent=5359"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/categories?post=5359"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/scienceillustrated.com.au\/blog\/wp-json\/wp\/v2\/tags?post=5359"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
