NASA has discovered two previously unobserved phenomena<\/a> in Saturn’s atmosphere, and so far, they can not explain what they are.<\/p>\nPublished in Geophysical Research Letters, the new peer-reviewed study notes a pair of atmospheric anomalies that includes a string of dark structures, not seen before on any planet in our Solar System.\u00a0<\/p>\n
The structures were found drifting in Saturn\u2019s ionosphere, with an asymmetric star-shaped pattern in the stratosphere directly below. Both features defy previous scientific predictions.<\/p>\n
The findings were observed in an area known as Saturn\u2019s sub-auroral ionosphere, a region roughly 1,100 kilometers above the planet’s clouds. The scientists discovered a chain of dark infrared-absorbing structures between 55\u00b0 and 65\u00b0 north latitude, which they are now calling \u201cdark beads\u201d.\u00a0<\/p>\n
The unusual structures were also said to have faint halos of brighter emission and were only present on one side of the planet.<\/p>\n
\u201cThese dark beads are most likely the result of thermospheric dynamics driven by ionospheric winds,\u201d the study explained.\u00a0<\/p>\n
\u201cNo known ionospheric planetary analog exists\u201d with the specific features the structures were displaying, the authors write.\u00a0<\/p>\n
This wasn\u2019t the only anomaly the researchers found, however. In the upper stratosphere, at an altitude of approximately 600 kilometers, they discovered a six-armed, star-shaped structure that was dark against the surrounding brightness. They noted that two of the six arms were missing from the shape, leaving a strange, asymmetric figure. It is said to be unlike anything previously recorded on Saturn or anywhere else.<\/p>\n
\u201cThe upper stratosphere appears to have an atmospheric formation unlike anything previously known,\u201d said the paper, and that this misshapen star is \u201cagain unlike anything previously observed at other planets.\u201d<\/p>\n
The two discoveries were made with NASA\u2019s James Webb Space Telescope, which is also being used to track the interstellar comet 3I\/ATLAS, a subject that remains largely mysterious to scientists.<\/p>\n
Renowned Harvard astrophysicist Avi Loeb recently published a new blog post claiming the interstellar comet 3I\/ATLAS is significantly larger than previous visitors. He added that the enormous size and unusual characteristics of 3I\/ATLAS are so unlikely for a natural object that it could potentially be an alien spacecraft.<\/p>\n
“The inferred mass of over 50 billion tons is at least a million times more than the inferred mass of 1I\/Oumuamua,” he wrote.<\/p>\n
He continued: “Why were we so fortunate to receive such a giant object as the third in the list of interstellar objects before witnessing a million objects of the size of 1I\/Oumuamua?<\/p>\n
“As I showed in my paper, there is not enough rocky material in interstellar space to accommodate the delivery of such a giant icy rock to the inner solar system over our survey period of a decade.”<\/p>\n
Loeb cautioned, “we’re screwed” if this object originates from a civilization with superior technological capabilities, and emphasized that global agencies need to stay vigilant and consider strategies should the comet prove to have an artificial origin.<\/p>\n","protected":false},"excerpt":{"rendered":"The majority of space remains a vast mystery to scientists, and it continues to be a constant source…\n","protected":false},"author":2,"featured_media":127306,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[23],"tags":[80213,85,77894,46,9795,10562,80212,141,145],"class_list":{"0":"post-127305","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-dark-beads","9":"tag-il","10":"tag-interstellar-comet-3i-atlas","11":"tag-israel","12":"tag-james-webb-space-telescope","13":"tag-saturn","14":"tag-saturns-atmosphere","15":"tag-science","16":"tag-space"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/127305","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=127305"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/127305\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/127306"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=127305"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=127305"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=127305"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
