This video of the Eagle Nebula showcases the superb resolution and wide field of view of NASA’s upcoming Nancy Grace Roman Space Telescope. It begins with a Hubble image of the famous Pillars of Creation superimposed on a ground-based image. The view then zooms out to show the full field of view of Roman’s Wide Field Instrument. Roman’s images will have the resolution of Hubble while covering an area about 100 times larger in a single pointing.Credit: L.

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.

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.Credit: NASA's Goddard Space Flight Center/CI LabWatch this video on the NASA.gov Video YouTube channel. 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.Credit: NASA's Goddard Space Flight Center/CI LabWatch this video on the NASA.gov Video YouTube channel. The Roman Space Telescope will make its microlensing observations in the direction of the center of the Milky Way galaxy. The higher density of stars will yield more microlensing events, including those that reveal exoplanets.Credit: NASA's Goddard Space Flight Center/CI LabWatch this video on the NASA.gov Video YouTube channel. 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.Credit: NASA's Goddard Space Flight Center/CI LabWatch this video on the NASA.gov Video YouTube channel. This animation illustrates the concept of gravitational microlensing with a rogue planet — a planet that does not orbit a star. When the rogue planet appears to pass nearly in front of a background source star, the light rays of the source star become bent due to the warped space-time around the foreground planet. This planet is then a virtual magnifying glass, amplifying the brightness of the background source star.Credit: NASA's Goddard Space Flight Center/CI Lab This animation illustrates the concept of gravitational microlensing with a black hole. When the black hole appears to pass nearly in front of a background star, the light rays of the source star become bent due to the warped space-time around the foreground black hole. It becomes a virtual magnifying glass, amplifying the brightness of the distant background star.Credit: NASA's Goddard Space Flight Center/CI Lab This animation illustrates the concept of gravitational microlensing with a black hole. When the black hole appears to pass nearly in front of a background star, the light rays of the source star become bent due to the warped space-time around the foreground black hole. It becomes a virtual magnifying glass, amplifying the brightness of the distant background star. Unlike when a star or planet is the lensing object, black holes warp space-time so much that it noticeably alters the distant star’s apparent location in the sky, as illustrated with the inset. The two images caused by lensing are too close to be spatially resolved, but changing brightness of the two images produce a shift in the position of the source. To illustrate the shift, the inset only shows how the position of the source changes without showing the brightening.Credit: NASA's Goddard Space Flight Center/CI LabWatch this video on the NASA.gov Video YouTube channel.

A planet discovered by NASA’s Transiting Exoplanet Survey Satellite (TESS) has pointed the way to additional worlds orbiting the same star, one of which is located in the star’s habitable zone. If made of rock, this planet may be around twice Earth’s size. The new worlds orbit a star named GJ 357, an M-type dwarf about one-third the Sun’s mass and size and about 40% cooler that our star. The system is located 31 light-years away in the constellation Hydra. In February, TESS cameras caught the star dimming slightly every 3.9 days, revealing the presence of a transiting exoplanet — a world beyond our solar system — that passes across the face of its star during every orbit and briefly dims the star’s light.The transits TESS observed belong to GJ 357 b, a planet about 22% larger than Earth. It orbits 11 times closer to its star than Mercury does our Sun.But while researchers were looking at ground-based data to confirm the existence of the hot Earth, they uncovered two additional worlds. The farthest-known planet, named GJ 357 d, is especially intriguing. The planet’s size and composition are unknown, but a rocky world with this mass would range from about one to two times Earth’s size. GJ 357 d is located within the outer edge of its star’s habitable zone, where it receives about the same amount of stellar energy from its star as Mars does from the Sun. If the planet has a dense atmosphere, which will take future studies to determine, it could trap enough heat to warm the planet and allow liquid water on its surface.GJ 357 c, the middle planet, has a mass at least 3.4 times Earth’s, orbits the star every 9.1 days at a distance a bit more than twice that of GJ 357 b. TESS did not observe transits from this planet, which suggests its orbit is slightly tilted — perhaps by less than 1 degree — relative to the hot Earth’s orbit, so it never passes across the star from our perspective.

Animation illustrating how a planet can disappear in a star's bright light, and how a coronagraph can reveal it. A coronagraph works by blocking the bright light of a star to allower dimmer objects, like orbiting exoplanets, to become visible. This in turn allows cameras to directly image the exoplanet.Direct imaging provides the critical approach to studying the detailed properties of exoplanets. Images and spectra of directly imaged planets provide some of the most powerful information about the structure, composition, and physics of planetary atmospheres. This information can in turn help scientists better understand the origin and evolution of these systems. The direct imaging technique is also naturally applicable to the nearest and brightest, and thus best-characterized, solar systems.Advancing the technology for direct imaging of exoplanets was the top priority medium-scale space investment recommended by NWNH. Coronagraphy on the Roman Space Telescope will be a major step towards the long-term goal of a mission that can image habitable Earth-mass planets around nearby stars and measure their spectra for signs of life.
