## Roman Telescope's Journey
NASA's Nancy Grace Roman Space Telescope is en route to its service station 930,000 miles from Earth.
## Webb Telescope's Mission
James Webb Space Telescope already explores the universe with high-resolution imaging technology.
## Field of View Difference
Roman has a wide field of view capturing huge sky patches while Webb has narrow field of view for detailed images.
## Mirror Technology
Webb's 21.3-foot primary mirror with 18 hexagonal segments provides high resolution but narrow field of view.
## Roman's Detector Advantage
Roman's 7.9-foot mirror with 18 sensors captures wider sky areas with less detail than Webb.
## Coronagraph Instrument
Roman's onboard Coronagraph blocks starlight to observe planets with greater detail.
## Telescope Partnership
Roman will find new stars and planets, then send Webb to examine discoveries in detail.
## Key takeaway

NASA's Nancy Grace Roman Space Telescope will find billions of new stars and planets, while James Webb Space Telescope provides high-resolution images of known objects.
