SPHEREx will survey the entire sky in 102 infrared wavelengths The mission will provide data on 450 million galaxies and 100 million s SPHEREx aims to explore the universe's early moments and galaxy formati Advertisement A groundbreaking space telescope is set to launch next month to map the cosmos in infrared light. The SPHEREx mission, officially known as the Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer, has been designed to provide scientists with a comprehensive map of the sky using spectroscopy. This approach will allow researchers to analyse the composition and distances of millions of galaxies and stars. The mission, expected to last two years, will collect data on more than 450 million galaxies and over 100 million stars in the Milky Way. Key questions about the universe's early moments, galaxy formation, and the presence of water in planetary systems will be explored. The spacecraft is currently undergoing final preparations for its scheduled launch from Vandenberg Space Force Base in California aboard a SpaceX Falcon 9 rocket on February 27. Mission Objectives and Scientific Impact According to NASA, SPHEREx will survey the entire sky in 102 wavelengths of infrared light, a capability that will offer insights into the earliest stages of the universe. The mission will help researchers examine conditions just after the Big Bang and track the evolution of galaxies. Data collected will also contribute to understanding how water and other essential elements formed in planetary systems.
