ALT LP 791-18 d, shown here in an artist's concept, is an Earth-size world about 90 light-years away. The gravitational tug from a more massive planet in the system, shown as a blue disk in the background, may result in internal heating and volcanic eruptions – as much as Jupiter’s moon Io, the most geologically active body in the solar system. Astronomers discovered and studied the planet using data from NASA’s Spitzer Space Telescope and TESS (Transiting Exoplanet Survey Satellite) along with many other observatories.

ALT Direct image of two planets around a Sun-like star, maked so you can see a screen over the very bright dot upper left. The direct image of a multi-planet system around a Sun-like star shows the planets, TYC 8998-760-1 b and c, as orange dots visible middle and lower right. Image credit: ESO/Bohn et al.
ALT An artist's concept illustration shows a large planet and a white orange star coming together with great flashes of gas and dust coming off. It is labeled illustration.
ALT An artist's concept illustration shows a clouded exoplanet against the black of space. The planet is glowing north of the center, appearing to come from beneath a heavy layer of clouds. The image is labeled Artist Concept.
ALT An illustration shows a yellow star with three planets crossing its face, with three more at different distances against a star-filled background. This is an artist's rendering of six planets orbiting a Sun-like star, Kepler-11. A newly discovered system, also likely with six planets, includes a "super-Earth" and four "mini-Neptunes."

ALT The 2023 NASA ExoExplorers Science Series welcomes two speakers for its virtual May talks. Junellie Gonazlez Quiles of Johns Hopkins University will speak on "Carbon Cycling on the TRAPPIST-1 Planets." Michelle Kunimoto from the Massachusetts Institute of Technology will present on "Diamonds in the Rough: Finding Thousands of New Planet Candidates Around Faint Stars." The event is scheduled for 11 a.m. PDT on Friday, May 12. More information about the event and the ExoExplorers program is posted at https://exoplanets.nasa.gov/exep/exopag/exoexplorers.
ALT The Webb telescope’s image of the dusty debris disk around the star Fomalhaut. On a dark background, a slanted oval in varying shades of rust orange extends from the 1 o’clock to 7’oclock positions. It features multiple layers, including 3 belts made up of objects analogous to asteroids and comets. Going from the outside-in, there is first a prominent outer ring, then a darker gap, an intermediate ring, a narrower dark gap, and finally a bright yellow-orange inner disk. At the center of the inner disk is a ragged black spot, indicating a lack of data due to saturation
ALT An annular solar eclipse, photographed on October 3, 2005. Because the Moon does not completely cover the Sun during an annular solar eclipse, the Moon in this photo appears as a dark disk on top of a larger, bright disk (the Sun). This creates what looks like a thin, golden and red ring with a pitch black background. Credit: Courtesy Stefan Seip
ALT A group of volunteers and a guide pause for a photo on an inflatable Zodiak raft. They wear cold-weather gear and masks as they collect and document the water and phytoplankton samples from the fjord they’re visiting. Behind their rubber boat we can see the rocky, snow-covered coastline of Antarctica. A large ship, partially visible in the upper right corner of the photo, awaits the return of these volunteers.
ALT An illustration of an exoplanet is shown with the two stars it orbits in a close range.
ALT NASA EXPRESS banner, with the NASA logo and the tagline "your STEM connection" and a collage of NASA-related drawings representing science, technology, engineering and mathematics. Missions highlighted include the International Space Station, the Space Launch System rocket, Orion spacecraft, X-59 supersonic aircraft, Mars rover, James Webb Space Telescope and the NASA Gateway
ALT Cartwheel Galaxy image captured by NASA’s James Webb Space Telescope’s Near-Infrared Camera (NIRCam) & Mid-Infrared Instrument (MRI). A large galaxy on the right, with two much smaller companion galaxies to the left at 10 o’clock and 9 o’clock. The large galaxy resembles a speckled wheel, with an oval outer ring and a small, off-center inner ring. The outer ring contains pink plumes like wheel spokes, with dusty blue regions in between. The inner ring is smoother, filled in with a more uniform pale pink. The two companion galaxies to the left, one above the other, are about the same size and both spiral galaxies. The background is black and full of more distant, orange-red colored galaxies of various sizes.
ALT Graphic titled “Exoplanet GJ 486 b Transmission Spectrum.” The y-axis is labeled “Amount of Light Blocked” and the x-axis has a scale that ranges from about 0.5 microns to over 5 microns. As you move right along the graph, two lines converge and become overlapping around 3 microns. An inset shows a legend with a yellow line labeled “starspots model,” a blue line labeled “water-rich atmosphere model,” and a white dot with gray, vertical error bar labeled “Webb data.”
ALT A young person on a wooden dock squats down next to the railing to get a good view of the water just beyond the dock’s edge. The person holds a smartphone with two hands in the horizontal orientation to capture a photo of the water, which is dark, still, and partially covered in lily pads.
ALT An artist concept illustration shows a large rocky exoplanet in the left foreground. A fiery red star is shown at the right with the black of space in the background. It is labeled Artist Concept.
