A supernova \u2014 the explosive death of a star \u2014 is always violent, blasting material into space while typically leaving behind a compact stellar remnant like a neutron star or black hole. But some supernovas involving the largest stars in the cosmos may be so immensely powerful they leave absolutely nothing behind.<\/p>\n
Scientists since the 1960s have theorized the existence of these ultra-powerful supernovas, and have now come up with evidence for them \u2014 albeit indirect \u2014 in research involving black \u200bholes and ripples in spacetime called gravitational waves.<\/p>\n
Such supernovas are predicted to occur in the most enormous stars \u2014 those with a \u200cmass around \u200c140 to 260 times greater than the sun, according to Hui Tong, a doctoral student in astrophysics at Monash \u200bUniversity in Australia and lead author of the study published on Wednesday in the journal Nature.<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"WASHINGTON \u2013 A supernova \u2014 the explosive death of a star \u2014 is always violent, blasting material into…\n","protected":false},"author":2,"featured_media":374165,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[1409,85,46,141,145],"class_list":["post-374164","post","type-post","status-publish","format-standard","has-post-thumbnail","category-science","tag-astronomy","tag-il","tag-israel","tag-science","tag-space"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/374164","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=374164"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/374164\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/374165"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=374164"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=374164"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=374164"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
