Unraveling the Mysteries of Dark Energy with NASA's WFIRST

The video explores the concept of dark energy, a mysterious force accelerating the universe's expansion. Discovered in 1998, dark energy remains largely unknown. NASA's WFIRST telescope aims to study it through redshift measurements, mapping galaxies, and observing Type 1a supernovas. These methods help determine distances and the universe's expansion rate. Additionally, Baryonic Acoustic Oscillations provide insights into galaxy clustering and dark energy's effects over time. WFIRST's comprehensive surveys will enhance our understanding of dark energy and its role in the universe's fate.
