00:00Because the obvious question is why do we need another telescope alongside Hubble
00:05and James Webb? The answer is the three of them do completely different things.
00:10That's the same reason why most smartphones today have two, three or even four cameras.
00:15Hubble is the reliable all-rounder in visible light. James Webb is the deep space telescope.
00:22With its massive 6.5 meter mirror, it peers extremely deep into tiny patches,
00:30capturing the faintest, most distant objects. Roman is the exact opposite, the panoramic camera.
00:37It's not about the depth of a single point, but the breadth of the entire sky. They complement each
00:44other best. Roman comes through vast areas and finds the interesting needles in the haystack.
00:51And James Webb then takes a really close look at each one of them.
