A galaxy cluster is a collection of hundreds to thousands of galaxies—a “city” of galaxies. Similar to our human cities, these cities of galaxies are busy, vibrant places with lots of activity. As the crossroads where galaxies interact, these cities provide us with important insights into many fundamental astrophysical processes. They also hold a hidden secret: There is more in them that what we can see. Join Dr. Montes as she visits the cosmic metropolis and unveils the hidden mysteries in clusters of galaxies.
