The history of women's contributions to the fields of science, technology, engineering, and math (STEM) is long and varied. But it has also often been overlooked or underrepresented. This series highlights only a very few of the women who have made important discoveries and have had a crucial impact on STEM fields. This, however, is not just a look into the past. Today, women are in every STEM discipline, in every type of job, and represent the widest range of background and experiences.

The Nancy Grace Roman Space Telescope is a next-generation space telescope that will survey the infrared universe from beyond the orbit of the Moon. The spacecraft's giant camera, the Wide Field Instrument (WFI), will be fundamental to this exploration. The WFI features the same angular resolution as Hubble but with 100 times the field of view. Data it gathers will enable scientists to discover new and uniquely detailed information about planetary systems around other stars. The WFI will also map how matter is structured and distributed throughout the cosmos, which should ultimately allow scientists to discover the fate of the universe.

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. | NASA's Goddard Space Flight Center/CI Lab | Video | 15.1 MB | MP4 | WFIRST_Microlensing_S4_4k_30fps_h264 | https://roman.gsfc.nasa.gov/exoplanets_microlensing.html | |
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 | https://roman.gsfc.nasa.gov/exoplanets_microlensing.html | |
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. | Credits: NASA’s Goddard Space Flight Center/Chris Smith (USRA/GESTAR) | Video | 884.9 KB | MP4 | Transit-Method-For-Detecting-Planets | https://roman.gsfc.nasa.gov/exoplanets_transit_method.html | |
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. | NASA's Goddard Space Flight Center/CI Lab | Video | 23 MB | MP4 | WFIRST_Microlensing_S1b_4k_30fps_h264 | https://svs.gsfc.nasa.gov/20315 | |
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 | https://svs.gsfc.nasa.gov/20315 | |
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 | https://svs.gsfc.nasa.gov/20315 | |
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 | Xallarap_Effect | https://svs.gsfc.nasa.gov/13795 | |
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. | NASA's Goddard Space Flight Center | Image | 96.1 KB | JPEG | mission_observations-transit-_mkv | https://www.nasa.gov/feature/goddard/2021/nasa-s-roman-mission-predicted-to-find-thousands-of-transiting-planets | |
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. | NASA's Goddard Space Flight Center | Animation | 2.9 MB | GIF | exo_dust_solar_system_5 | https://www.nasa.gov/feature/goddard/2022/how-nasas-roman-could-help-find-other-earths-by-surveying-space-dust |

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. | Matthew T.

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. | NASA, Joseph Olmsted (STScI) | Image | 13 MB | PNG | STScI-01GG86D49QPMKSME3SRCNANW2Y | https://hubblesite.org/contents/news-releases/2022/news-2022-049.html | |
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. | NASA, Alyssa Pagan (STScI) | Video | 20.8 MB | MP4 | STScI-01GG7YDFPZZAQYWC0WF0NMW4C9 | https://hubblesite.org/contents/news-releases/2022/news-2022-049.html |

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. | NASA, ESA, and A.

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). | SCIENCE: Joshua Peek (STScI) ILLUSTRATION: Robert L.

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. | IMAGE: NASA, ESA IMAGE PROCESSING: Joseph DePasquale (STScI) ACKNOWLEDGMENT: University of Geneva, Pascal Oesch (University of Geneva), Mireia Montes (UNSW) | Image | 26.4 MB | PNG | STScI-01FF84JQ7RMQXS5ZX222PP5VA8 | https://stsci.box.com/s/1kjkcd9019o0cu1rg0vrt56wzjx8n8y5 | https://hubblesite.org/contents/news-releases/2021/news-2021-048.html |

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. | Illustration: NASA, ESA, and A. Feild (STScI);

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. | NASA's Goddard Space Flight Center Music: "Pulse and Glow" from Adrift in Time.

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. | NASA’s Goddard Space Flight Center/F.

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. | NASA, ESA, Leah Hustak (STScI) | Image | 1.3 MB | PNG | Roman_CosmologicalRedshift_Vertical_v3 | https://svs.gsfc.nasa.gov/14107 | |
This 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. | SCIENCE: NASA, ESA, STScI, Casey Papovich (TAMU) IMAGE PROCESSING: Alyssa Pagan (STScI) | Image | 18 MB | PNG | STScI-01G407SYE55D51SYNVZ4Z1VY8Q | https://hubblesite.org/contents/news-releases/2022/news-2022-018.html?filterUUID=5f9d3684-88ed-4633-b385-93fd21831642 | |
NASA’s Nancy Grace Roman Space Telescope will be a powerful tool for studying galaxies throughout the cosmos. It will be able to provide spectra for every galaxy in its field of view. And with a field of view 200 times that of the Hubble Space Telescope at infrared wavelengths, Roman can capture thousands of objects of interest in a single observation. | VIDEO: Robert L.

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. | ANIMATION: NASA, ESA, Joseph DePasquale (STScI) | Video | 43.7 MB | MP4 | STScI-01FF870TZDSHXK3E22AX5XXVG4 | https://hubblesite.org/contents/news-releases/2021/news-2021-048.html |

This illustration compares the relative sizes of the areas of sky covered by two surveys: Roman’s High Latitude Wide Area Survey, outlined in blue, and the largest mosaic led by Hubble, the Cosmological Evolution Survey (COSMOS), shown in red. In current plans, the Roman survey will be more than 1,000 times broader than Hubble’s. Roman will also explore more distant realms of space than most other telescopes have probed in previous efforts to study why the expansion of the universe is speeding up. | NASA's Goddard Space Flight Center | Image | 3.8 MB | JPEG | roman_hls_mkiii_2 | https://stsci.box.com/s/x8gtecqqdonl5zdm3nkxq4pw75l20wa9 | https://www.nasa.gov/feature/goddard/2021/nasa-s-roman-mission-will-help-empower-a-new-era-of-cosmological-discovery |

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.
