The Cosmic Background Explorer (COBE) and Wilkinson Microwave Anisotropy Probe (WMAP) revolutionized our understanding of the early period in the universe’s evolution. At that time, the seeds were planted for all the large-scale structures we see today, such as galaxies and galaxy clusters. In this video, Astronomy Associate Editor Daniel Pendick explains what COBE and WMAP have taught us.
