NASA's Goddard Space Flight Center/CI Lab | Video | 29.5 MB | MOV | WFIRST_exoplanet_Coronagraph_V2_H264_1080p | https://roman.gsfc.nasa.gov/exoplanets_direct_imaging.html | 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.

This animation illustrates the concept of gravitational microlensing. When one star in the sky appears to pass nearly in front of another, the light rays of the background source star become bent due to the warped space-time around the foreground star. This star is then a virtual magnifying glass, amplifying the brightness of the background source star, so we refer to the foreground star as the lens star. If the lens star harbors a planetary system, then those planets can also act as lenses, each one producing a short deviation in the brightness of the source. Thus we discover the presence of exoplanets, and measure its mass and separation from its star. NASA's Goddard Space Flight Center | Video | 20.7 MB | MP4 | WFIRST_Microlensing_S1a_4k_30fps_h264
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 | Roman_expected_planets-lg | https://roman.gsfc.nasa.gov/exoplanets_microlensing.html | 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.

At top is the way it could appear to a telescope able to resolve the features. The source star appears to move and distort as its light is warped by the closer lensing star and its planet. At bottom is a light curve showing the intensity of light from the event. As the two stars reach best alignment, the signal reaches its peak. The planet orbiting the lensing star is detectable as a brief change in brightness. NASA's Goddard Space Flight Center/CI Lab | Video | 23 MB | MP4 | WFIRST_Microlensing_S1b_4k_30fps_h264
This pair of animations compare signals from two planet detection methods – microlensing (top) and transit (bottom) – for high- and low-mass planets. Microlensing signals from small planets are rare and brief, but they’re stronger than the signals from other methods. NASA's Goddard Space Flight Center/CI Lab | Video | 19.9 MB | MP4 | WFIRST_Microlensing_S2_4k_30fps_h264
The Roman Space Telescope will have Hubble-like angular resolution since it will orbit above Earth’s atmosphere, enabling it to separate host and source stars from microlensing events. Its wide field of view will allow the Roman Space Telescope to classify planets’ stars on an unprecedented scale, adding to our understanding of the type of systems throughout the galaxy – including those like our own. NASA's Goddard Space Flight Center/CI Lab | Video | 21.8 MB | MP4 | WFIRST_Microlensing_S5_4k_30fps_h264
This animation demonstrates the xallarap effect (which is parallax in reverse). As a planet moves around its host star, it exerts a tiny gravitational tug that shifts the star’s position a bit. This can pull the distant star closer and farther from a perfect alignment. Since the nearer star acts as a natural lens, it’s like the distant star’s light will be pulled slightly in and out of focus by the orbiting planet. By picking out little shudders in the starlight, astronomers will be able to infer the presence of planets. NASA's Goddard Space Flight Center | Animation | 2.1 MB | GIF |

The same kind of dust in other planetary systems, called exozodiacal dust, creates a similar haze that makes it challenging to detect orbiting worlds.

This graphic illustrates how cosmological redshift works and how it offers information about the universe’s evolution. The universe is expanding, and that expansion stretches light traveling through space. The more it has stretched, the greater the redshift and the greater the distance the light has traveled. As a result, we need telescopes with infrared detectors to see light from the first, most distant galaxies.

This simulated image illustrates the wide range of science enabled by Roman's extremely wide field of view and exquisite resolution. The yellow 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. A blue 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.

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.
