Coming soon: the world's 'most colourful' map of the cosmos.
NASA's SPHEREx telescope, launching today, will create an unprecedented multi-coloured map of the entire sky by dividing light into 96 distinct spectral bands. Unlike Webb and Hubble, which examine tiny portions of space in high detail, this compact but powerful instrument will survey the full sky every six months, cataloging over 450 million galaxies and 100 million stars.
