SPHEREx: NASA's All-Sky Mapping Observatory Begins Science Operations
2025-05-02

After weeks of preparation, NASA's SPHEREx space observatory has commenced its science mission, capturing approximately 3,600 unique images daily to create an unprecedented map of the cosmos. Mapping the entire sky in 102 infrared wavelengths, SPHEREx aims to unlock mysteries about the universe's origins, galaxy evolution, and the building blocks of life. By using spectroscopy, it will create four all-sky maps, investigating cosmic inflation and searching for water in distant galaxies. The mission's vast dataset will be publicly available, furthering astronomical research.
