Welcome to Laniakea, your home: 素晴らしい new 3D 地図／計画する 明らかにする／漏らすs gigantic 最高の-cluster of 星雲s that 含む／封じ込めるs our own 乳の Way
- Word means 'immeasurable heaven' in Hawaiian?
- Structure is 500 million light years across?
- 含む／封じ込めるs 100,000 星雲s and the 集まり of a hundred quadrillion suns
- Around Laniakea are four 隣人ing superclusters known as Shapley, Hercules, 昏睡 and Perseus-Pisces?
- First supercluster to have its size mapped by 天文学者s.?
It may not be stamped in your パスポート, but everyone on Earth is now 公式に a 国民 of Laniakea.
That is the 指名する scientists have given the gigantic 最高の-cluster of 星雲s that 含む／封じ込めるs our own 乳の Way, which is 明らかにする／漏らすd in a 素晴らしい new 3D 活気／アニメーション.
The word means 'immeasurable heaven' in Hawaiian - an appropriate description for a structure 500 million light years across that 含む／封じ込めるs 100,000 星雲s and the 集まり of a hundred quadrillion suns.

Scientists have long-known that 星雲s are not 分配するd 無作為に but congregate together in clusters.
On the largest 規模s, 星雲s are strung out like pearls, forming glowing 'filaments'.?
Where these intersect they produce enormous 'superclusters' of 星雲s whose 動議 is 影響する／感情d by gravity.

The 乳の Way sits 近づく the 辛勝する／優位 of one such supercluster, the first to have its size mapped by 天文学者s.
Within Laniakea, 星雲s flow inwards に向かって a 地域 called the 広大な／多数の／重要な Attractor, the 同等（の） of a large gravitational valley.
Around Laniakea are four 隣人ing superclusters known as Shapley, Hercules, 昏睡 and Perseus-Pisces.?

Dr Brent Tully, from the University of Haw aii in Honolulu, led the team of scientists that mapped Laniakea's 境界s from 測定s of the velocities of 地元の 星雲s.
The 研究員s compared the galactic flow with that of water in a landscape of hills and valleys, tracing the outer surface of a 地域 where the 逮捕する-動議 of 星雲s was inward.
They wrote in the 定期刊行物 Nature: 'We define a supercluster to be the 容積／容量 within such a surface, and so we are defining the extent of our home supercluster, which we call Laniakea.'
