Are We About to Cancel the Key To Solving Dark Energy? With Dr. Megan Donahue
888The Nancy Grace Roman Space Telescope could help solve the mystery of dark energy, but its future is uncertain. Astrophysicist Dr. Megan Donahue joins John Michael Godier to explore how this repurposed spy satellite will map cosmic expansion, study galaxy clusters, and detect distant exoplanets. If launched, Roman may reshape our understanding of the universe.
