Rogue planets are free-floating planets that do not orbit a star and instead travel through space. Scientists think they are outcasts from developing planetary systems and may be very numerous throught the galaxy.  This illustration shows a rogue planet traveling through space.

This animation shows how a planet can disappear in a star’s bright light, and how a coronagraph, such as the one that will be used on Roman, can reveal it.

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.

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.

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.

This animation illustrates two ways a gravitational microlensing event could look to an observer. 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.

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.

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.

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.

This graphic highlights the search areas of three planet-hunting missions: the upcoming Nancy Grace Roman Space Telescope, the Transiting Exoplanet Survey Satellite (TESS), and the retired Kepler Space Telescope. Astronomers expect Roman to discover roughly 100,000 transiting planets, worlds that periodically dim the light of their stars as they cross in front of them. While other missions, including Kepler's extended K2 survey (not pictured in this graphic), have unveiled relatively nearby planets, Roman will reveal a wealth of worlds much farther from home.

This animation zooms out from our solar system and shows how the sunlight scattered by zodiacal dust is brighter than the planets when viewed from afar. 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 Roman simulated image is 1/140th a Roman field of view. There are so many stars at the center of our galaxy that in other telescopes’ views they may blur together, but Roman will see them with high clarity, distinguishing stars in the center bulge from those in the surrounding disk. Tracking the precise positions and colors of individual stars over time will provide insight on the star-formation processes in the Milky Way bulge, bar, and disk.

NASA’s Nancy Grace Roman Space Telescope, will capture the equivalent of 100 high-resolution Hubble images in a single shot, imaging large areas of the sky 1,000 times faster than Hubble. In several months, the Roman Space Telescope could survey as much of the sky in near-infrared light—in just as much detail—as Hubble has over its entire three decades.

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.

Following its launch no later than May 2027, NASA’s Roman Space Telescope will survey the same areas of the sky every few days. Researchers will mine these data to identify kilonovae – explosions that happen when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the resulting debris is ejected as jets, which move near the speed of light. The remaining debris produces hot, glowing, neutron-rich clouds that forge heavy elements, like gold and platinum. Roman’s extensive data will help astronomers better identify how often these events occur, how much energy they give off, and how near or far they are.

How will NASA’s Roman Space Telescope detect kilonovae – brief flashes of light sent out by the merger of two neutron stars or a neutron star and a black hole? In part, due to the telescope’s wide field of view. Roman’s view is 200 times larger than the Hubble Space Telescope’s infrared view. Once Roman starts observing the sky at a regular cadence following its launch, planned by 2027, researchers expect to be able to identify more of these spectacular events, both nearby and very far away. Although we do not yet know the rate of these events, when Roman’s data pour in we will begin to learn how frequent these mergers are – and what results.

This composite image illustrates the possibility of a Roman Space Telescope “ultra deep field” observation. In a deep field, astronomers collect light from a patch of sky for an extended period of time to reveal the faintest and most distant objects. This view centers on the Hubble Ultra Deep Field (outlined in blue), which represents the deepest portrait of the universe ever achieved by humankind, at visible, ultraviolet and near-infrared wavelengths. Two insets reveal stunning details of the galaxies within the field.

Beyond the Hubble Ultra Deep Field, additional observations obtained over the past two decades have filled in the surrounding space. These wider Hubble observations reveal over 265,000 galaxies, but are much shallower than the Hubble Ultra Deep field in terms of the most distant galaxies observed.

These Hubble images are overlaid on an even wider view using ground-based data from the Digitized Sky Survey. An orange outline shows the field of view of NASA’s upcoming Nancy Grace Roman Space Telescope. Roman’s 18 detectors will be able to observe an area of sky at least 100 times larger than the Hubble Ultra Deep Field at one time, with the same crisp sharpness as Hubble.

(2011) Astronomers have pushed NASA's Hubble Space Telescope to its limits by finding what they believe is the most distant object ever seen in the universe. Its light traveled 13.2 billion years to reach Hubble, roughly 150 million years longer than the previous record holder. The age of the universe is 13.7 billion years.

In a map of the Milky Way, the neighboring spiral arm just beyond the Sun is known as the Perseus arm. Astronomers created this map by measuring the locations of natural radio sources known as masers (pink dots in pullouts at right) and dust clouds (blue dots). At upper right, a shaded region shows the previously believed shape of the Perseus arm, demarcated by a combination of masers and dust clouds. New measurements (middle right) show that some of these dust clouds are much closer or farther from the Sun than originally thought. As a result, the Perseus arm may be much clumpier and less well-defined (lower right).

This portion of the Hubble GOODS-South field contains hundreds of visible galaxies. A representative sample of those galaxies on the right half of the image also have their spectra overlayed in a representation of slitless spectroscopy. By using slitless spectroscopy, a spectrum is obtained that contains both spatial and wavelength information. For example, the inset highlights a spiral galaxy that shines brightly in the emission line of hydrogen-alpha (Hα) as well as in broad starlight (the horizontal strip of light). Its spiral shape is traced by the Hα portion of the spectrum. By combining imaging and spectroscopy, astronomers can learn much more than from each technique alone.

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.

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

This video dissolves between six cubes to show the simulated distribution of galaxies at redshifts 9, 7, 5, 3, 2, and 1, with the corresponding cosmic ages shown. As the universe expands, the density of galaxies within each cube decreases, from more than half a million in the first cube to about 80 in the last. Each cube is about 100 million light-years across. Galaxies assembled along vast strands of gas separated by large voids, a foam-like structure echoed in the present-day universe on large cosmic scales.

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.

infographic showcases the difference in data volume between the Nancy Grace Roman and Hubble space telescopes. Each day, Roman will send over 500 times more data back to Earth than Hubble.

Hubble image features four of the thousands of galaxies found within the Hubble Ultra Deep Field. All of the highlighted galaxies show evidence of vigorous star formation (blue regions filled with hot, young stars). In the insets at right, the near-infrared spectrum of each galaxy is displayed. By examining a galaxy’s spectrum, you can learn about the ages of its stars, its star-formation history, how many heavy chemical elements it contains, and more.

Upon entering operations in 2027, the Nancy Grace Roman Space Telescope will be able to collect spectra for every object in its field of view, which is 200 times larger than Hubble’s in infrared light. As a result, it will enable studies of rare galaxies from a period known as “cosmic noon,” when many galaxies went through growth spurts.

This animation portrays the complementary nature of imaging and spectroscopy to understand galaxies. It begins with a portion of the Hubble GOODS-South field, a region of the sky containing hundreds of visible galaxies. Then rainbow-colored lines called spectra are added next to selected galaxies; in reality, every star and galaxy has its light spread out. The underlying image later fades away to highlight the galaxies’ spectra, which contain a wealth of information including distances (redshifts). The image and spectra were obtained by Hubble and illustrate what will be done with Roman, but over a vastly larger number of galaxies.

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. Bottom left: This magnified view illustrates how Roman will be able to resolve bright stars even in the dense cores of globular star clusters. Bottom right: A zoom of the CANDELS-based background shows the density of high-redshift galaxies Roman will detect.

Comparison of Hubble and expected Rubin Observatory LSST data resolution. (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.
