ESA approves Arrakihs to map faint galaxy haloes and decode cosmic history
TL;DR
The European Space Agency has adopted Arrakihs, a fast F-class mission designed to map ultra-faint galaxy haloes and stellar streams to reveal how galaxies like the Milky Way form and evolve. Using a four-camera binocular instrument spanning near-UV to near-IR, Arrakihs will study at least 80 Milky Way–mass galaxies to piece together merger histories, with a launch targeted for 2030.
