Blanco Telescope in Cerro Tololo, Chile, recorded 3.32 billion celestial objects in our galaxy, the Milky Way, of which roughly 2 billion are stars. It is the largest survey of its kind to date. \u201cImagine a group photo of over three billion people and every single individual is recognizable,\u201d Debra Fischer, division director of astronomical sciences at the US National Science Foundation (NSF), one of the agencies that funded the project, told the Harvard and Smithsonian Center for Astrophysics. When added to a map of 2 billion objects created in 2017, the resulting image covers about 6.5% of the night sky and measures 130 degrees across, an area 13,000 times larger than the full Moon. By observing wavelengths in the near-infrared range, the scientists were able to look past the space dust that absorbs light and hides the faintest stars. An innovative approach to data processing allowed them to reduce the effect of the dust and gas clouds and better predict what might be behind each star (<em>Astrophysical Journal Supplement Series <\/em>and <em>Harvard &amp; Smithsonian Center for Astrophysics<\/em>, January 18).<\/p>\n","protected":false},"excerpt":{"rendered":"Telescope in Chile captures the most detailed image of the Milky Way&#8217;s stars and dust clouds","protected":false},"author":475,"featured_media":479101,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_exactmetrics_skip_tracking":false,"_exactmetrics_sitenote_active":false,"_exactmetrics_sitenote_note":"","_exactmetrics_sitenote_category":0,"footnotes":""},"categories":[1651],"tags":[205],"coauthors":[785],"class_list":["post-478093","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-notes","tag-astronomy"],"acf":[],"_links":{"self":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/478093","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/users\/475"}],"replies":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/comments?post=478093"}],"version-history":[{"count":4,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/478093\/revisions"}],"predecessor-version":[{"id":479113,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/posts\/478093\/revisions\/479113"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media\/479101"}],"wp:attachment":[{"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/media?parent=478093"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/categories?post=478093"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/tags?post=478093"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/revistapesquisa.fapesp.br\/en\/wp-json\/wp\/v2\/coauthors?post=478093"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
