NASA’s newest space telescope—SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer)—launched in March 2025 on a mission to create an all-sky map of the universe. Now settled into low-Earth orbit, SPHEREx has begun delivering data to a public archive on a weekly basis, allowing anyone to use the data to probe the secrets of the cosmos.

NASA is committed to the sharing of scientific data, promoting transparency and efficiency in scientific research. In line with this commitment, data from SPHEREx appears in the public archive within 60 days after the telescope collects each observation.
The SPHEREx mission contributes to NASA’s key scientific goals to discover the secrets of the universe and search for life beyond Earth. Its all-sky map will help scientists answer major questions about why the large-scale structure of the universe looks the way it does, how galaxies form and evolve, and the origins and abundance of water and other key ingredients for life in our galaxy.
