Roman's Top 3 Game-Changing Capabilities

The Nancy Grace Roman Space Telescope is equipped with advanced instruments designed to provide unprecedented insights into dark energy, exoplanets, and large-scale cosmic structures.

The top 3

1. 100x Wider Field of View than Hubble: Roman's Wide Field Instrument (WFI) will image an area 100 to 200 times larger than Hubble's infrared view, enabling rapid surveys of vast cosmic regions with comparable resolution.
2. Mapping Dark Energy and Dark Matter: A primary goal for Roman is to investigate dark energy and dark matter by mapping billions of galaxies and tracking how these mysterious components have influenced the universe's expansion and structure.
3. Uncovering Thousands of Exoplanets via Microlensing: Roman will conduct the first space-based microlensing survey, which is highly sensitive to discovering cold, low-mass exoplanets, including Earth-analogs and free-floating planets, by detecting temporary brightness spikes from background stars.
