\t<\/p>\n\n\t\t\t\t\t\tThe Roman Space Telescope\u2019s broad field of view, exquisite sensitivity, and fast survey speed will unveil the evolving universe in ways that have never been possible before.\t\t\t\t\t<\/p>\n
\t\t\t<\/p>\n
To fulfill the mission\u2019s top-level science objectives, Roman will conduct three core community surveys plus a suite of general astrophysics surveys using the Wide Field Instrument (WFI), along with a set of technology demonstration observations undertaken with the Coronagraph Instrument. The core surveys include the High-Latitude Wide-Area Survey, Galactic Bulge Time-Domain Survey, and High-Latitude Time-Domain Survey.\u00a0\u00a0<\/p>\n
Links below describe the core surveys, which were defined<\/a> through an open, community-driven process. The General Astrophysics observing programs, as well as funding to work with Roman data, will be competed and selected through future processes. The surveys and programs all relate to at least two of the mission\u2019s three main science themes: measuring dark energy, investigating exoplanets, and great observatory astrophysics and planetary science.<\/p>\n All Roman observations will be publicly available with no period of limited access.<\/p>\n \t\t\t\t\tGalactic Bulge Time-Domain Survey\t\t\t\t<\/p>\n \t\t\t\t\tHigh-Latitude Time-Domain Survey\t\t\t\t<\/p>\n \t\t\t\t\tHigh-Latitude Wide-Area Survey\t\t\t\t<\/p>\n \n\t\t\t\t\t\t\t\t\tGalactic Bulge Time-Domain Survey\n\t\t\t\t\t\t\t\t<\/p>\n Tracking how stars change in brightness over time to discover distant worlds<\/p>\n Tracking how hundreds of millions of stars change in brightness will unveil thousands of newfound worlds with a wide range of characteristics (including rogue planets) and isolated stellar-mass black holes.<\/p>\n \n\t\t\t\t\t\t\t\t\tHigh-Latitude Time-Domain Survey\n\t\t\t\t\t\t\t\t<\/p>\n Revealing the dynamic universe beyond our galaxy<\/p>\n Astronomers will use this survey to probe our dynamic universe by observing the same region of the cosmos every five days for two years. Stitching these observations together will create movies that will uncover a wealth of transient objects, like exploding stars, stars being swept into black holes, and neutron star mergers.<\/p>\n \n\t\t\t\t\t\t\t\t\tHigh-Latitude Wide-Area Survey\n\t\t\t\t\t\t\t\t<\/p>\n Making a 3D map of the universe<\/p>\n This survey will combine the powers of imaging and spectroscopy to uncover hundreds of millions of galaxies. Roman’s wide and deep 3D images will allow astronomers to explore the structure and expansion of the universe as it evolved through cosmic time.<\/p>\n Additional Observations<\/p>\n \t\t\t\tImaging Exoplanets<\/p>\n Roman will demonstrate direct imaging technology by observing worlds that are Jupiter\u2019s size circling Sun-like stars, and photographing planets that are up to several billion years old \u2013 something that has never been done before. These results will pave the way for future missions to study worlds that are even more Earth-like.<\/p>\n
