First light images from SPHEREx, captured March 27, 2025. These give a tantalizing first look at SPHEREx’s wide, multi-wavelength view of the sky. Each bright spot is a source, typically a star or a galaxy. Each image is expected to contain more than 100,000 detected sources. There are six images in every SPHEREx exposure — one for each detector. The top three images show the same area of sky as the bottom three images, spanning the observatory’s full 3.5 x 11.5 deg field of view. When the SPHEREx observatory begins routine science operations in April, it will take approximately 600 exposures every day.

Two overlapping 3.5 x 3.5 deg spectral images of the Galactic plane taken in band 2 and band 5. In band 2 (covering wavelengths 1.1 – 1.6 um) we see significant obscuration by intervening dust.
