Roman's High-Latitude Time-Domain Survey infographic (IMAGE)
Caption
This infographic describes the High-Latitude Time-Domain Survey that will be conducted by NASA’s Nancy Grace Roman Space Telescope. The survey’s main component will cover over 18 square degrees — a region of sky as large as 90 full moons — and see supernovae that occurred up to about 8 billion years ago. Smaller areas within the survey will pierce even farther, potentially back to when the universe was around a billion years old. The survey will be split between the northern and southern hemispheres, located in regions of the sky that will be continuously visible to Roman. The bulk of the survey will consist of 30-hour observations every five days for two years in the middle of Roman’s five-year primary mission.
