The Roman Space Telescope has the same size mirror as Hubble, but it will survey the sky up to 1,000 times faster — not because it sees deeper, but because it sees wider: each Roman image captures a patch of sky at least 100 times larger, making Hubble’s method look like counting a crowd one face at a time.

Roman uses a Hubble-size mirror, but its Wide Field Instrument captures far more sky per exposure, allowing surveys up to 1,000 times faster.
