拉尼亚凯亚超星系团 Meaning
/lā ní yà kǎi yà chāo xīng xì tuán/
- technical
Laniakea is the galaxy supercluster that is home to the Milky Way and approximately 100,000 other nearby galaxies. The name comes from Hawaiian, meaning "immeasurable heaven," which perfectly captures the vast, interconnected web of gravity that defines our local corner of the universe. In academic or scientific contexts, it is used to describe the large-scale structure of the cosmos. It is often contrasted with other superclusters to explain the complex, filament-like architecture of the observable universe, emphasizing that galaxies are not randomly scattered but organized into massive, flowing streams.
What is 拉尼亚凯亚超星系团?
Laniakea is a massive galaxy supercluster identified in 2014 that encompasses the Milky Way and approximately 100,000 other galaxies. It spans about 520 million light-years in diameter and is defined by the flow of galaxies toward a common gravitational center known as the Great Attractor.
