by H?l?ne Courtois
Overview :
How a team of researchers, led by the author, discovered our home galaxy's location in the universe.You are here: on Earth, which is part of the solar system, which is in the Milky Way galaxy, which itself is within the extragalactic supercluster Laniakea. And how can we pinpoint our location so precisely? For twenty years, astrophysicist H?l?ne Courtois surfed the cosmos with international teams of researchers, working to map our local universe. In this book, Courtois describes this quest and the discovery of our home supercluster.Courtois explains that Laniakea (which means ?immense heaven? in Hawaiian) is the largest galaxy structure known to which we belong; it is huge, almost too large to comprehend?about five million light-years in diameter. It contains about 100,000 large galaxies like our own, and a million smaller ones. Writing accessibly for nonspecialists, Courtois describes the visualization and analysis that allowed her team to map such large structures of the universe.
