How to Find a Galaxy

How do you find a galaxy? How do you find a thousand galaxies? Astrophysicist Dr. Margaret Geller is a galaxy mapping pioneer. She and her colleagues studied the spatial distribution of galaxies in our universe by surveying a wide swath of space, revealing stunning patterns… “the largest patterns in nature, on a scale of hundreds of millions of light years.” From her bio at Harvard’s Center for Astrophysics:

Dr. Geller’s long-range scientific goals are to discover what the universe looks like and to understand how it came to have the rich patterns we observe today. To put the pieces of this grand puzzle together her research projects range from the structure of our own galaxy, the Milky Way, to mapping the distribution of the mysterious, ubiquitous dark matter in the universe.
