Astronomers<\/a> have finally solved an over 50-year mystery about the supermassive black hole<\/a> at the center of our Milky Way galaxy<\/a>.<\/p>\n

Most black holes produce wind or jets as they eat surrounding materials. Until now, no one could find the wind produced by Sagittarius A*<\/a>, the one controlling our galaxy\u2019s growth and evolution.<\/p>\n

But the most detailed view of the black hole yet has provided a much clearer view of what they say is 20,000-year-old wind, helping scientists better understand its role in the cosmos.<\/p>\n

\u201cUnless a black hole exists in a perfect vacuum, it must blow a wind somehow,\u201d Mark Gorski, an astrophysicist at Northwestern University who co-led the study, explained in a statement<\/a>. \u201cAnd there is no perfect vacuum in the universe.\u201d<\/p>\n

\u201cWith new observations, this is the first time we\u2019ve had a clean enough view to see the wind\u2019s imprint. We looked at the data and said, \u2018There it is. There is the thing that everybody\u2019s been looking for for 50 years,\u2019\u201d he said.<\/p>\n

\"Astronomers<\/p>\n

Astronomers say they\u2019ve solved a longstanding mystery about Sagittarius A*, the supermassive black hole in the center of our galaxy. The white dot in the center of this composite image shows the black hole, the orange and blue areas mark surrounding gas and X-ray data and a cone-shaped cavity seen in the orange data is the key to their findings (X-ray: NASA\/CXC\/Northwestern Univ.\/M. Gorski; Radio: ESO\/NAOJ\/NRAO\/ALMA; Image processing: NASA\/CXC\/SAO\/K. Arcand and P. Edmonds)<\/p>\n

The researchers used five years of observations from the Atacama Large Millimeter\/Submillimeter Array radio telescopes in Chile, peering through gas and dust previously obscuring our view of Sagittarius A*.<\/p>\n

Capturing an image of the gas near the black hole, the researchers then corrected it to reduce the black hole\u2019s radio signals, which are emitted from matter around the black hole.<\/p>\n

The image was 100 times deeper and 80 times sharper than previous maps of the region, allowing the scientists to see areas that were invisible in past photos.<\/p>\n

\"Data<\/p>\n

Data from the Atacama Large Millimeter\/Submillimeter Array (ALMA) radio telescopes in Chile maps the location of cold gas around Sagittarius A* in this image (X-ray: NASA\/CXC\/Northwestern Univ.\/M. Gorski; Radio: ESO\/NAOJ\/NRAO\/ALMA; Image processing: NASA\/CXC\/SAO\/K. Arcand and P. Edmonds)<\/p>\n

That\u2019s how they found a massive, cone-shaped hole without gas, which could only have been created by hot wind.<\/p>\n

Winds produced by stars around the black hole are not powerful enough to carve out a region this size, they say.<\/p>\n

\u201cIf you blow hot material from the black hole, it\u2019s not going to want to exist with the cold material,\u201d Gorski said. \u201cIt\u2019s either going to push the cold material out or heat it up. And, if it\u2019s too hot, you will no longer see the cold gas.\u201d<\/p>\n

\"This<\/p>\n

This composite image of the Milky Way center was made using data from the Atacama Large Millimeter\/Submillimeter Array radio telescopes and X-ray data from NASA\u2019s Chandra X-ray Observatory (ALMA(ESO\/NAOJ\/NRAO)\/S. Longmore et al. Background: ESO\/D. Minniti et al.)<\/p>\n

\u201cThe wind is not powerful, and its direction probably wanders with time. It shows that our black hole is not unique, and our place in the universe is not unique,\u201d Elena Murchikova, who co-led the study with Gorski, said.<\/p>\n

The observations indicate the black hole is in a quieter phase. Although, there has been evidence of past disruptions, and NASA\u2019s Chandra X-ray Observatory previously saw X-ray emissions in the same region as the cone-shaped hole.<\/p>\n

Sagittarius A* was first discovered in 1974<\/a>.<\/p>\n

\"X-ray<\/p>\n

X-ray data from NASA\u2019s Chandra X-ray Observatory shows the area around the black hole (X-ray: NASA\/CXC\/Northwestern Univ.\/M. Gorski; Radio: ESO\/NAOJ\/NRAO\/ALMA; Image processing: NASA\/CXC\/SAO\/K. Arcand and P. Edmonds)<\/p>\n

\u201cExceptional claims require exceptional evidence,\u201d Gorski said. \u201cWe wanted to make sure that we weren\u2019t just looking at some sort of imaging artifact. Then, the X-ray image from Chandra just slotted in perfectly. The molecular features lined up.\u201d<\/p>\n

\u201cWhen you find something that no one has seen before, the first thought that runs through your mind is not \u2018Oh my God, we made a discovery,\u2019\u201d Murchikova said. \u201cIt\u2019s \u2018Oh my God, what\u2019s wrong with my analysis?\u2019 But when we overlaid our image with the X-ray image, it started to make sense.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"Astronomers have finally solved an over 50-year mystery about the supermassive black hole at the center of our…\n","protected":false},"author":2,"featured_media":716027,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7],"tags":[2035,49,48,35928,259351,66,24768],"class_list":["post-716026","post","type-post","status-publish","format-standard","has-post-thumbnail","category-science","tag-black-holes","tag-ca","tag-canada","tag-image-processing","tag-mark-gorski","tag-science","tag-supermassive-black-hole"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/716026","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=716026"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/716026\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/716027"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=716026"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=716026"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=716026"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
