The team will be observing massive structures of galaxies, called galaxy clusters, using the Keck I telescope on the summit of Maunakea on the big island of Hawai'i. The primary goal of the team is, however, not to observe the galaxy clusters themselves, but to harness their awsome power as cosmic telescopes to gravitationally magnify very distant galaxies behind the clusters. These very distant galaxies are likely among some of the first that formed in the universe, when the universe is less than 10% of its current age! Very little is known about the properties of these primeval galaxies and the observations taken by the team will help to provide insights into their makeup and how they form and evolve, as well as the state of the universe about 13 billion years ago.
