The Roman surveys will search for planets toward the center of our Milky Way galaxy, which is heavily populated with stars. The higher density of stars will yield more microlensing events, including those that reveal exoplanets.

Kepler and other exoplanet search efforts have discovered thousands of large planets with small orbits, represented by the red and black dots on this chart. Roman will find planets with a much wider range of masses orbiting farther from their host star, shown by the blue dots. NASA’s Goddard Space Flight Center, adapted from Penny et al. (2019) | Image | 1.2 MB | PNG |
This animation shows a planet crossing in front of, or transiting, its host star and the corresponding light curve astronomers would see. Using this technique, scientists anticipate Roman could find 100,000 new worlds.

Inside the Roman footprint is simulated Roman data, which you can see more clearly in the three pull-outs - each one being a Hubble field-of-view.

Although Roman has not yet opened its wide, keen eyes on the universe, astronomers are already running simulations to demonstrate what it will be able to see and plan their observations. This simulated image of a portion of our neighboring galaxy Andromeda (M31) provides a preview of the vast expanse and fine detail that can be covered with just a single pointing of the Roman Space Telescope. Using information gleaned from hundreds of Hubble observations, the simulated image covers a swath roughly 34,000 light-years across, showcasing the red and infrared light of more than 50 million individual stars detectable with Roman.

This simulated image illustrates the wide range of science enabled by Roman's extremely wide field of view and exquisite resolution. The purple squares, which all contain background imagery simulated using data from Hubble’s Cosmic Assembly Near-infrared Deep Extragalactic Survey (CANDELS) program, outline the area Roman can capture in a single observation. An orange square shows the field of view of Hubble’s Wide Field Camera 3 for comparison. While the CANDELS program took Hubble nearly 21 days to survey in near-infrared light, Roman’s large field of view and higher efficiency would allow it to survey the same area in less than half an hour. Top left: This view illustrates a region of the large nearby spiral galaxy M83. Top right: A hypothetical distant dwarf galaxy appears in this magnified view, demonstrating Roman’s ability to detect small, faint galaxies at large distances. Bottom left: This magnified view illustrates how Roman will be able to resolve bright stars even in the dense cores of globular star clusters.

Shorter, unnarrated version of the animation above.
This animation explains how BAOs arose in the early universe and how astronomers can study the faint imprint they made on galaxy distribution to probe dark energy’s effects over time. In the beginning, the cosmos was filled with a hot, dense fluid called plasma. Tiny variations in density excited sound waves that rippled through the fluid. When the universe was about 400,000 years old, the waves froze where they were. Slightly more galaxies formed along the ripples. These frozen ripples stretched as the universe expanded, increasing the distance between galaxies. Astronomers can study this preferred distance between galaxies in different cosmic ages to understand the expansion history of the universe.
The small peak near the center of the graph in this video shows how BAOs subtly influenced galaxy distribution. Today, there is a slight bump in the probability of finding galaxies about 500 million light-years away from each other. This distance shrinks as we look farther out into space, to earlier cosmic times.
Waves of sound – BAOs – ripple through the primordial cosmic sea in this animated gif.

The Nancy Grace Roman Space Telescope is a clue-hunter. As a survey mission, Roman will observe areas of the sky repeatedly, much like going back to the room multiple times to look for new details, or details that may have changed. It will cast a wide net with Hubble Space Telescope-quality data, but with 200 times Hubble’s infrared field of view! The infrared Roman mission will greatly expand our view of the universe, and it will provide many more clues to help solve some the greatest mysteries of astrophysics. | Illustration: J.

As a survey mission, the Nancy Grace Roman Space Telescope will collect Hubble-quality data but with 200 times Hubble’s infrared field of view. It will view planets by the thousands, galaxies by the millions, and stars by the billions. It will transmit almost 1,400 gigabytes of information to the ground each day—more than the storage space of an average home computer. For comparison, the Hubble Space Telescope sends less than 3 gigabytes a day, and the James Webb Space Telescope sends less than 60 gigabytes. After just five years of observing, Roman will have delivered 20,000 terabytes! All of this data will provide a treasure trove of information to scientists for many years to come. | Illustration: J.

(L) BVz color image from the Hubble CANDELS field with θ = 0.1” and r ≈ 28.5. Roman will have comparable resolution. (R) Simulated Rubin LSST image made by degrading Hubble data to Rubin resolution of θ = 0.6”. In the Rubin image, the galaxy is blended with surrounding objects. Correlating overlapping Rubin and Roman imagery would make it possible to develop machine learning algorithms to deblend Rubin imagery that does not overlap with Roman. Annotated version.
