SPHEREx

NASA’s SPHEREx mission will survey the sky in near-infrared to probe cosmic inflation and the history of galaxy formation.

How SPHEREx Will Test Cosmic Inflation

How SPHEREx Will Test Cosmic Inflation

August 8, 2026 | SPHEREx | Earnest S. Carroll

Learn how NASA’s SPHEREx mission will map the sky in 102 infrared colors to test the theory of cosmic inflation, probing the universe’s first moments and the seeds of all structure.
