The SPHEREx mission, set to launch on Thursday, aims to map over 450 million galaxies using infrared technology to study how galaxies form and evolve. The spacecraft will survey the sky in 102 infrared colors, offering a unique perspective on some of the universe’s oldest stars and galaxies. By using spectroscopy, scientists can analyze the composition, density, temperature, and motion of galaxies, unlocking answers about galaxy formation and the origin of water and organic materials in the Milky Way.
In addition to studying galaxy formation, the SPHEREx mission will investigate cosmic inflation, a theory that explains the early rapid expansion of the universe after the Big Bang. This mission could help scientists better understand the physics behind cosmic inflation and why it occurred. By tracing the distribution of hundreds of millions of galaxies in three dimensions, the SPHEREx mission could provide valuable insights into the origins of the universe.
The mission, which has been in development for about a decade and costs $488 million, is highly anticipated in the scientific community for its potential to make groundbreaking discoveries about the universe. By studying galaxies, cosmic inflation, and the origins of the universe, the SPHEREx mission could significantly advance human knowledge of fundamental physics and help answer some of the most enduring questions in astronomy.
