拉尼亞凱亞超星系團是銀河系、太陽系和地球所處的超星系團。2014年9月,夏威夷大學的布倫特·塔利(Brent Tully)和法國裡昂第一大學的海倫·庫爾圖瓦(Helene Courtois)所領導的團隊發表了一種通過星系的視向速度來定義超星系團的新方法,並由此定義了拉尼亞凱亞。按照新的定義,以往我們所知的室女座超星系團只是拉尼亞凱亞的一部分而已。
The rania subgalaxy cluster is the supercluster of galaxies, the solar system and the earth. In September 2014, brent, a professor at the university of Hawaii, tully and Helen at the university of Lyon in France the first Kurt tuva, led by the team published a regard to speed through the galaxy for defining a new method of superclusters, which defines the rania turning. According to the new definition, the virgo supercluster is just a part of la caja.
宇宙目前已知的最大結構是大尺度纖維狀結構——就像一張巨大的網,而這些纖維組成了宇宙中空洞的邊界。宇宙的空洞中,幾乎空無一物。「纖維」則是由超星系團所組成。鄰近拉尼亞凱亞超星系團的其他超星系團有夏普力超星系團、武仙座超星系團、后髮座超星系團、英仙-雙魚超星系團。這些超星系團和拉尼亞凱亞超星系團之間的邊界在拉尼亞凱亞超星系團被確認存在時仍無法清楚地判定。
The largest known structure in the universe is the large scale fibrous structure - like a giant net, which makes up the empty boundaries of the universe. The void of the universe was almost empty. The "fiber" is made up of superclusters. Other superclusters in the vicinity of rania's supercluster include the xia puli supercluster, the supercluster of the hercules, the supercluster in the rear, the infa-pisces supercluster. The boundary between these superclusters and the rania's supercluster was not clearly determined at the time when the rania supercluster was confirmed.
拉尼亞凱亞這個詞來自於夏威夷語,意為「無盡的天堂」。這個名稱是由任教於卡比奧拉尼社區學院的夏威夷語副教授 Nawa'a Napoleon 所建議的。這個名稱是向利用天文知識在太平洋中航行的玻里尼西亞人致敬。
The word "kaya" comes from the Hawaiian word meaning "endless paradise". The name was suggested by Nawa 'a Napoleon, an associate professor of Hawaiian who teaches at the school of community college in cabolani. The name is a tribute to the Polynesian peoples who use astronomical knowledge to navigate the Pacific.
拉尼亞凱亞超星系團內包含約10萬個星系,範圍達到約1.59億秒差距(5.2億光年)。質量相當於太陽的10^17倍,或者是銀河系的10萬倍,我們的銀河系就位於這張宇宙之網的一條「流蘇」上。拉尼亞凱亞超星系團幾乎與巨大的時鐘座超星系團相同。拉尼亞凱亞超星系團包含以下三個部分,而這三個部分先前被認為是各自分離的超星系團:
拉尼亞凱亞超星系團內最巨大的星系團包含室女座星系團、長蛇座星系團、半人馬座星系團、阿貝爾3565、阿貝爾3574、阿貝爾3521、天爐座星系團、波江座星系團和矩尺座星系團。整個超星系團由大約300到500個已知的星系團和星系群組成,而實際數字可能更高,這是因為部分天區被銀河系的隱匿帶遮蔽而無法被觀測。
超星系團是宇宙中最大的結構之一,並且其邊緣難以判斷,尤其是由內向外觀測時。發現拉尼亞凱亞的團隊使用電波望遠鏡將本星系群的星系運動繪製成分布圖。在特定超星系團內,所有星系的運動都會朝向超星系團的質量中心。而在拉尼亞凱亞超星系團,星系都朝向它的重力中心,巨引源移動,因此也影響了銀河系所在地本星系群和其他超星系團內的星系。
The rania supercluster contains about 100,000 galaxies, ranging in size from about 159 million second (520 million light years). Quality equivalent to 10 ^ 17 times the mass of the sun, or 100000 times that of the Milky Way, our own Milky Way galaxy is located the Zhang Yuzhou web of a "fringe". Rania's supercluster is almost the same as the giant clock constellation supercluster. The rania supercluster contains the following three parts, which were previously thought to be separate superclusters:
Virgo supercluster, the galaxy's supercluster.
The long snake - centaurus supercluster contains the gravity center of the rania's supercluster, the great source (also known as the "great gravitational source").
Peacock - Indian supercluster
Rania KaiYaChao clusters within the greatest clusters containing virgo cluster, hydra clusters, the centaurus cluster, abell 3565, abell 3574, 3521, fornax cluster Abel, wave jiang cluster and Norma clusters. The supercluster from about 300 to 500 known of clusters and clusters of galaxies, and the actual number may be higher, this is because the part of the region is the Milky Way's hidden take shelter and could not be observed.
The supercluster is one of the largest structures in the universe, and its edges are hard to judge, especially when observed from the inside out. The team found that rania's team used radio telescopes to map the group of galaxies in the galaxy. In a particular supercluster, all galaxy movements are directed toward the center of the supercluster. In the rania supercluster, the galaxy is moving toward its center of gravity, which moves the source, thus affecting the galaxy clusters and other supercluster galaxies in the Milky Way.
