Hey Space Placers!
You really have to read this press release, see the graphics and watch the video regarding our newly identified galactic supercluster - Laniakea, which means "immense heavens" in Hawaiian.
We live in the Milky Way Galaxy (MWG). It is part of a local cluster of galaxies called the Local Group.
The Local Group is connected to Laniakea which comprises 100,000 galaxies spread out over 500 million light years and containing the mass of over 100 million billion Suns! Wow.
Astronomers continue to define the Universe and our place in it with new instruments, detectors and more powerful computers. But great mysteries remain such as Dark Energy and Dark Matter.
