    At @NASA, we undertake the near impossible. This month, a first-of-its-kind mission will launch to boost our Swift observatory before it re-enters Earth’s atmosphere. Follow along with this daring, rapid-response effort to advance American spacecraft servicing technology.

    Not quite a planet. Not quite a star. Help NASA search for elusive brown dwarfs hiding in WISE telescope images as part of the new Backyard Worlds: Binaries project. Learn more: go.nasa.gov/3QoEpEQ

    Have you signed up to send your name to space yet?! We've seen your comments and made improvements to the site so that even more of you can now send us your names to be aboard the Nancy Grace Roman Space Telescope. go.nasa.gov/RomanNames
    A person in a head-to-toe white cleanroom suit holds a large purple "boarding pass" for NASA's Nancy Grace Roman Space Telescope in Goddard's large cleanroom. To the right of the person is a large half cylinder white shaped container with the telescope inside and to the left is a banner that has the NASA Goddard logo.

    How powerful are gamma-ray bursts, the biggest explosions since the big bang? 💥 You could pop 10 million billion trillion trillion kernels of popcorn from the energy of one! Find out how satellites like Swift and Fermi study them: go.nasa.gov/3T1aljg

    It's a little dusty over at MCG+08-11-002. This odd-looking galaxy sports a spectacular band of dark dust across its center, which is likely the aftermath of an earlier collision of two separate galaxies. Learn more: go.nasa.gov/4ev2jHT
    A glowing galaxy shines at the center of the image, surrounded by star-studded black space. The galaxy glows bright white and blue, but has swirling dark brown dust covering its center.

    🎶 Black Hole Star 🎶 Aren’t those the lyrics? @NASAWebb discovered Little Red Dots in 2022 and researchers are working to connect pieces of the puzzle. By analyzing one dot’s spectrum, the team has found evidence that it is a black hole star. go.nasa.gov/4uKB3Km
    A field of galaxies against the black background of space. In the center is a bright-white elliptical galaxy that is the core of the Abell S1063 galaxy cluster. Around the core are short, curved red lines, which are distant background galaxies magnified and warped by gravitational lensing. A couple of foreground stars appear large and bright with Webb’s signature eight-point diffraction spike pattern. Toward the very bottom, slightly off center toward the right, is a small red dot that is highlighted by an orange square outline. A larger orange square in the top right corner shows the object in more detail. The object, labeled “GLIMPSE-17775” looks like a fuzzy red dot with a yellow core.

    New upgrades to the Cold Atom Lab aboard the @Space_Station are helping scientists take precise measurements of quantum phenomena that happen at the atomic level. Learn more: jpl.nasa.gov/news/nasas-qua…
    Astronaut Jessica Meir inspects optical fibers while installing hardware updates to NASA’s Cold Atom Lab, or CAL, aboard the International Space Station on May 8, 2026. About the size of a minifridge, CAL enables researchers to explore quantum physics.

    You've got a friend in me, Euclid! Last year, @esa's Euclid space telescope paused its usual observations to look at the heart of our Milky Way Galaxy, previewing one of Roman’s major surveys.
    Image by ESA's Euclid providing an earlier snapshot of a region of our galaxy that Roman will repeatedly observe in the upcoming years. The color ombres like a sunset, from dark maroon in the upper left to a lighter orange and then yellow in the lower right. At the right of the frame, thick molecular clouds appear as dark patches that obscure parts of the galactic bulge beyond. Toward the left, the view rises to higher galactic latitudes: the yellow glow of the bulge becomes clearer, with fewer and more isolated foreground clouds interrupting the starlight.

    Our TESS telescope helped find two new “super-puff” planets that are about the size of Jupiter but have the density of cotton candy. TOI-791 b and c might even be the puffiest planets ever found! Further study can help us learn about planetary evolution. go.nasa.gov/4v6Oyo0
    An illustration of exoplanets TOI-791 b (left) and c orbiting their host star amidst a dark sky speckled with stars. Both planets are blue and brightly lit on their left sides by their star, which is depicted as a glowing yellow orb. The right side of each planet is darkly shadowed. Though both planets are similar in size, the one on the right is closer and appears much larger. The top of this planet is marbled with wispy white clouds. The image is watermarked with “Artist’s concept” and “Credit: NASA/Daniel Rutter.”
    Illustrations of puffy exoplanets TOI-791 b (left) and c are compared to familiar planets from our solar system. The top of the image, labeled “TOI-791 Exoplanets Comparison,” shows TOI-791 b and c as bright blue planets. Planet c is slightly larger, darker, and has a few wispy white clouds at its top. Below, images of Earth, Neptune, Uranus, Saturn, and Jupiter are lined up in order of size for comparison. TOI-791 b is about the same size as Jupiter, but TOI-791 c is slightly larger. The image is watermarked with “Artist’s concept” and “Credit: NASA/Daniel Rutter.”

    This could be your Roman empire. Apply to join us for a NASA Social at @NASAKennedy as we launch the @NASARoman Space Telescope on Aug. 30. Experience the launch firsthand, and help us tell the story of NASA's spectacular new space explorer. go.nasa.gov/4a9LEap
    Side view of Roman's optical telescope assembly. The assembly looks like the tip of a dull pencil. The primary mirror is a shiny, silver circle, like a CD. Six black struts extend from the edge of the primary mirror to a black cylinder, which houses the secondary mirror.

    Rubin + Hubble = 🤩🌌 Hubble recently celebrated 36 years in space with a detailed look into the Trifid Nebula, a star-forming region about 5,000 light-years away, seen in this “inset” image: go.nasa.gov/4eCozOP
    A ground-based photo of the full Trifid Nebula is shown on the left half with an inset image from the Hubble Space Telescope at right. At left, an irregular mostly opaque circle takes up the majority of the view. The circle has a bright pink interior crossed with a few dark, jagged dust lanes. A significant region around that appears blue. The edges have shades of orange and brown, with the star-filled black background of space peeking through. Hubble’s close-up is outlined just below center to the left. The top left is bright blue. Brown and amber colors run from top right through the center in irregular, overlapping lines to the bottom-center. At bottom right, the view is almost black. Tiny, amber-colored stars appear throughout the scene. Toward the left there is a prominent brown shape that looks like a head with two horns.
