For the first time, NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to ripples in space-time. Unlike the star-hugging transiting planets TESS regularly reveals, the newfound world is a super-Jupiter orbiting far from its host star.
“When TESS launched, no one expected it to ever be capable of finding this kind of planet,” said Diana Dragomir, a professor at the University of New Mexico in Albuquerque and co-author of a paper describing the results. At 1.6 times Jupiter’s mass and a similar orbital distance, it would be extremely unlikely to find such a planet via the primary detection method TESS was designed for. “The discovery implies that there are probably other so-called microlensing planets hiding in TESS’s data that we hadn’t previously thought to look for.”

Astronomers found the first hint of the planet, called Gaia23bra b, in 2023 using ESA’s (European Space Agency) now-retired Gaia space telescope. Gaia’s alert system flagged a star that brightened — something that can happen when a foreground star passes in front of a more distant one and magnifies its light through gravitational microlensing.
Researchers later looked back through archived TESS data and found TESS had caught it too.
“Gaia’s observations were too sparse to pick up on the planet,” said Mallory Harris, a Ph.D. candidate at the University of New Mexico, who led the study. “The TESS spacecraft happened to be monitoring the same area of the sky during the event, and its denser time coverage showed extra features in the light curve caused by a planet.”
The team’s analysis, published July 1 in The Astrophysical Journal Letters, revealed that Gaia23bra b, which orbits an orange dwarf star that’s about 80 percent of the Sun’s mass, is nearly 40,000 light-years away from Earth, far exceeding TESS’s usual search radius of about 150 light-years.
Out of more than 6,000 known exoplanets (worlds outside our solar system), about three-fourths were discovered via the transit method, TESS’s typical planet-hunting technique. Astronomers monitor hordes of stars, watching for ones that periodically dim as orbiting planets cross in front of them — an event called a transit.

Microlensing has revealed less than 5% of known exoplanets. This light-bending phenomenon occurs when two stars align closely from our vantage point. Light from the more distant star curves as it travels through the warped space-time caused by the nearer star’s mass.
If the alignment is especially close, the nearer star acts like a cosmic lens, focusing and magnifying light from the background star. Planets orbiting the foreground star may also modify the distant star’s light, acting as their own tiny lenses. Astronomers see the effect as a spike in the star’s brightness.
The transit method is best at finding large planets orbiting very close to their host stars; large planets block the most starlight, while close-in planets are more likely to pass in front of the host star. These gargantuan, steamy worlds are fascinating to scientists, but astronomers want to find planets like those in our solar system, too. That’s microlensing’s specialty.

Microlensing isn’t well suited to finding huge, close-in planets because their gravitational signals would just blur together.
“Transits and microlensing are complementary because they each reveal a category of planet the other may not be able to detect,” Dragomir said. “And they offer different details. Transits give us the size of a planet, and in concert with other methods we can determine its mass and density. Microlensing gives us masses and orbital distances for planets we’d otherwise never see.”

But microlensing observations are time-limited opportunities.

Ph.D. candidate at the University of New Mexico
That makes detailed observations of microlensing planets tough. However, the method can serve as a powerful demographics tool that offers broad information about planetary populations.
“This is a bit like a preview of the microlensing NASA’s Nancy Grace Roman Space Telescope will do,” said Michael Fausnaugh, a professor at Texas Tech University in Lubbock and a co-author of the study. On track for launch on August 30, 2026, Roman will observe the center of the Milky Way galaxy for one of its core surveys, revealing an estimated 1,000 microlensing planets and around 100,000 transiting planets.
Roman will specifically target the heart of the galaxy because stars are packed so tightly together there, increasing the odds of seeing microlensing events. While that crowding would make many stars blend together in TESS’s larger pixels, TESS looks at nearly the whole sky, where stars are more spread out.
“Since TESS looks elsewhere in the galactic plane, it can naturally find microlensing planets in other parts of the galaxy, as demonstrated by this first microlensing planetary system,” Dragomir said. “That means it could help us study planets in regions with different conditions.”
That could have implications for the search for habitable worlds. The bustling galaxy center is rife with radiation from more frequent supernova explosions, which could sterilize planets. And gravitational encounters between crowded stars may disrupt planetary systems. Observations from TESS focus on a milder part of the galaxy.
“The key to Roman’s microlensing survey is its dense time coverage targeting the galactic bulge,” Fausnaugh said. “The TESS mission uniquely provides these rapid observations for stars in other parts of the galaxy, and pairing the two opens up prospects for understanding planet formation in a diverse population of stars. Since microlensing finds solar system-like planets, this offers a new chance to understand how planetary systems like our own vary in different regions of the galaxy.”

In celebration of the 250th birthday of the United States, NASA has unveiled four cosmic images from its Chandra X-ray Observatory rendered in red, white, and blue that represent the wonders of the universe the agency explores. The images are accompanied by a trio of new sonifications – a technique that translates astronomical data into sounds.
The image set begins with Cassiopeia A in the top panel, where X-rays from Chandra (represented in blue and purple) have been combined with an infrared image from NASA’s James Webb Space Telescope (red and white). Chandra’s X-ray vision reveals the blast wave that tore through the star, as well as elements in the debris field like iron, calcium, and oxygen. Webb’s infrared data also shows the expanding shell of material from the explosion and cosmic dust throughout the remnant.
In the bottom row, the first image on the left is the nebula NGC 3603, which contains a massive cluster of stars and is located in the Milky Way Galaxy. This new composite image contains Chandra’s X-ray data (red and white) and shows diffuse emissions near the galaxy’s center along with point-like X-ray sources throughout the middle of the image. Optical, infrared, and ultraviolet light from NASA’s Hubble Space Telescope (red-orange, green, blue, and yellow) reveal stars in the center of the image and dust and gas toward the bottom. The combined layering of the colors makes this nebula and the stars forming within it appear primarily red, white, and blue, with X-rays showing the sparkling lights of young stars.
The middle panel of the bottom row is a new look at the galaxy NGC 4736, also known as Messier 94. In this image, X-rays of different wavelengths from Chandra (red, orange, and blue) are layered with a visible light image from astrophotographers using their telescopes on the ground (red, green, and blue). Messier 94 is a spiral galaxy with a bright inner ring around it, called a starburst ring, where new stars are forming, perhaps fueled by gas driven in the unique oval-shaped structure seen here.
The final image in this red, white, and blue quartet features ZwCl 0024+1652. This is a distant galaxy cluster in which astronomers have found evidence for dark matter by using specially processed data from Hubble (blue). Another image from Hubble reveals the individual galaxies in the cluster (appearing as yellow and white). X-ray data from Chandra shows the enormous reservoir of superheated gas that pervades this galaxy cluster (red) with much more mass than all the galaxies taken together.
New sonifications of the three images along the bottom row of this mosaic are also available, allowing listeners to experience data through sound.
The translation of NGC 3603 into sound begins with a left to right scan, where the brightnesses of the sources once again dictate volume. Chandra’s observations of compact sources sprinkled throughout the galaxy are heard as piano notes, while the diffuse X-ray emission is mapped to a range of audio frequencies. The Hubble optical data is played as sustained tones and acoustic guitar harmonics.
In the sonification of NGC 4736, the radar-like scan moves clockwise, and the brightness of the sources dictates the volume of the sounds. X-rays from Chandra have been turned into wind-like sounds that follow the shape of the X-ray emission. Neutron stars and stellar-mass black holes (known as “compact sources”) detected by Chandra are mapped to pitched tones on a glass marimba. Optical data from ground-based observations is mapped to musically pitched tones, creating a low drone, while stars and background galaxies are heard as a soft piano.
For ZwCl 0024+1652, the sonification begins as a circle on the outside of the image and moves inward. The volume is linked to the brightness of the data, reaching one peak as the circle passes over the dark matter detected by inference from Hubble optical observations and another as it reaches the core. The background stars are heard as a swelling glockenspiel-like sound, and the galaxies are played on a piano. Chandra’s X-rays, which dominate the center of the galaxy cluster and reveal superheated gas, are represented by airy synthesizer notes.
The sonification program is led by the Chandra X-ray Center (CXC) and included as part of NASA’s Universe of Learning program. The collaboration was driven by visualization scientist Kimberly Arcand, (CXC), Matt Russo, astrophysicist; and Andrew Santaguida, musician, SYSTEM Sounds project; along with Christine Malec, consultant. Previously released sonifications of data from Cassiopeia A can be found at chandra.si.edu/sound.
NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

In celebration of the 250th birthday of the United States, this release includes a series of images featuring four wonders of the universe, rendered in red, white, and blue. The images contain X-ray data from the Chandra X-ray Observatory, optical and infrared data from the Hubble Space Telescope and the James Webb Space Telescope, as well as ground-based telescopes.
The main image set features composite images of the four individual objects; Cassiopeia A, NGC 3603, M94/NGC 4736, and ZwCl 0024+1652.
Cassiopeia A occupies the top panel of the frame, significantly larger than the other images in the set. The cloudy blast-wave of the supernova remnant is ring-like in shape, streaked with veins of iron, calcium, and oxygen. Here, presented in red, white, and blue, the remnant resembles an electrified donut, crackling with marbled veins of strawberry and blueberry icing.
At our lower left of the image set is the nebula NCG 3603, which contains a massive cluster of stars on the other side of the Milky Way galaxy. Here, a tight cluster of neon red and white stars packs the center of the image, dissipating as it reaches the outer edges of the panel. Sweeping in at the lower corners of the image are hazy blue clouds resembling sheets of gauze.
Centered at the bottom of the image set is the galaxy NGC 4736, also known as Messier 94 (M94). Here, the spiral galaxy is seen face on, with concentric pale violet cloud rings flecked with scores of stars in white, pale blue, soft red, and golden yellow. The inner ring of the galaxy is bright, and rosy yellow in color. This is a starburst ring, where new stars are forming.
At our bottom right of the image set is the distant galaxy cluster ZwCl 0024+1652. The image is packed with streaks and specks in golden yellow and brilliant white. Upon close inspection, each streak and speck is revealed to be an individual galaxy, some with discernible spiral shapes. At the center of the image is a round pool of bright red light, surrounded by royal blue haze. The red light represents X-ray observations by Chandra, which reveal an enormous reservoir of superheated gas pervading the cluster. The blue haze represents specially-processed data from Hubble, suggesting evidence of dark matter.
This release also includes new sonifications of the three images presented in the bottom row of this data set, allowing listeners to experience the data through sound.

Flight testing is a team sport. For nearly 80 years, teams at NASA’s Armstrong Flight Research Center in Edwards, California, have used flight testing to push the limits of aerodynamics and advance aviation.
Earlier this year, NASA’s Crossflow Attenuated Natural Laminar Flow (CATNLF) initiative tested a wing concept that would maximize the smooth flow of air known as laminar flow, which could lower fuel costs for future airliners. During flight testing, researchers strapped a scale-model CATNLF wing to the bottom of a NASA F-15 aircraft.
Here’s what a day of CATNLF flight testing looked like.

Ground crews ready the aircraft for the mission. If the operation involves a chase plane — a second aircraft to monitor the test flight — it would also be prepared, along with its crew.
Pilots, engineers, maintenance techs, project leads, researchers, photographers, and videographers meet to review the flight’s goals, weather reports, and final details.

Researchers head to the control room to complete day-of checks, confirming all communications, displays, and instruments are functioning.
Pilots suit up in life support, including custom‑fit pressure suits, harnesses, helmets, and masks. If a photographer, videographer, or flight test engineer will be in the aircraft’s back seat, they do the same.
The pilot completes preflight checks with the crew chief and technicians for the aircraft’s electrical systems. The pilot and the crew chief sign a flight preparedness report confirming the aircraft is ready to fly.
Inside the control room, the team prepares to monitor the flight using the same set of test cards, a step-by-step plan for the flight.
The pilot and backseat crew member climb into their seats, strap in, and secure any gear they’ve brought for the test. The pilot completes preflight ground checks.
The pilot communicates with the control tower and taxis to the runway. Control room teams at NASA Armstrong monitor the aircraft via radio.
The pilot accelerates down the runway and, at the proper speed, pulls back on the stick to take off. Once airborne, the pilot coordinates with air traffic control at Edwards Air Force Base and the NASA Armstrong control room while flying to the designated test area.

At the test location, the team coordinates with the pilot on altitude, speed, and maneuvers. The test conductor relays each task, and the pilot completes them one-by-one. The pilot and control room monitor the performance of the hardware, instruments, aircraft, or software throughout the sequence. After completing the test points, the pilot returns to base.
The pilot lands and taxis to the ramp at NASA Armstrong, where the crew chief meets the jet. After the pilot exits, the aircraft is towed into the hangar for maintenance.
The pilot, project team, and mission controlstaff return to the briefing room tocapture lessons learned and document items for follow-up.
Teams download flight data for analysis. If two flights are scheduled, preparations begin immediately for the second.

Nota del editor: Este comunicado se actualizó el 30 de junio de 2026 para aclarar la versión de desarrollo de ingeniería del rover PROMISE.
La NASA anunció el martes la selección de tres empresas para llevar a cabo cuatro nuevas misiones a la Luna a finales de 2028 como parte del programa Base Lunar de la agencia. Astrobotic, Firefly Aerospace e Intuitive Machines entregarán cargas útiles científicas de la NASA a la superficie lunar mientras la agencia construye el primer puesto de avanzada en otro mundo.
“Estas nuevas adjudicaciones a nuestros socios comerciales, que suman casi 600 millones de dólares para enviar más misiones a la Luna con cargas útiles científicas, demuestran nuestro compromiso de acelerar el esfuerzo para establecer una presencia a largo plazo en la superficie lunar, y nos brindan más oportunidades para desarrollar las capacidades que necesitamos para prosperar allí”, dijo Lori Glaze, administradora asociada de la Dirección de Misiones de Vuelos Espaciales Tripulados de la sede central de la NASA en Washington.
A Astrobotic se le adjudicaron 297,9 millones de dólares en total para dos entregas, mientras que Firefly Aerospace e Intuitive Machines recibieron 144,2 y 148,3 millones de dólares, respectivamente, para una entrega cada una, como parte de la iniciativa de Servicios Comerciales de Carga Útil Lunar (CLPS, por sus siglas en inglés) de la agencia, uno de los pilares de Base Lunar. Cada una usará versiones actualizadas de diseños de módulos de aterrizaje que ya han volado, para permitir la mayor cadencia de misiones de la NASA.
“Estamos construyendo un campo de pruebas para las operaciones de Base Lunar”, dijo Ryan Stephan, director interino de módulos de aterrizaje de carga del programa Base Lunar de la NASA. “Acelerar la cadencia con la que adjudicamos nuevas misiones a la Luna y las oportunidades de lanzamiento nos permite avanzar rápidamente para aprender, repetir y mejorar”.
Con 17 misiones de entrega a la superficie lunar a cargo de múltiples proveedores, la NASA también anunció nuevas oportunidades para que la industria estadounidense contribuya a la Base Lunar. La agencia está barajando planes para enviar a la Luna el Vehículo de Exploración Polar para Observación, Cartografía y Exploración In Situ (PROMISE, por su acrónimo en inglés), una versión de desarrollo de ingeniería del rover Perseverance en Marte. Los expertos de la agencia definirán las posibles oportunidades de PROMISE para caracterizar la superficie lunar y el subsuelo, y para prospectar recursos.
Además, la NASA tiene previsto solicitar propuestas en los próximos meses para módulos de aterrizaje lunar que transporten una demostración de tecnología de energía y aviónica, otro conjunto de cargas científicas y un generador de imágenes ópticas del Polo Sur. La NASA también publicará una convocatoria abierta para demostraciones tecnológicas de la Base Lunar y solicitará propuestas para una constelación de retransmisores de comunicaciones y navegación lunar para mejorar la comunicación entre los elementos de la Base Lunar y la Tierra.
Las adjudicaciones anunciadas el 30 de junio desempeñarán un papel fundamental en el establecimiento de la infraestructura para las operaciones en la superficie lunar. Las empresas son responsables de iniciar y ejecutar los procesos de contratación proporcionar una evaluación de un módulo de aterrizaje lunar previo similar e incorporar las lecciones aprendidas para mejorar la fiabilidad general de la misión.
Cada entrega llevará tres cargas útiles de la NASA a la superficie lunar:
La agencia también está estudiando opciones para que estos módulos de aterrizaje entreguen otras cargas útiles a la Luna.
“Al enviar los mismos instrumentos científicos en varios módulos de aterrizaje, comprenderemos mejor los posibles peligros durante el aterrizaje y crearemos una red global de datos ambientales y marcadores de ubicación en la Luna”, dijo Joel Kearns, administrador asociado adjunto para la exploración de la Dirección de Misiones Científicas en la sede central de la NASA. “Es similar a tener estaciones meteorológicas en distintos lugares de la Tierra. Estas tres cargas útiles han demostrado su fiabilidad en vuelo y sus datos son fundamentales para apoyar la exploración segura de la superficie lunar con seres humanos”.
La NASA avanza en el desarrollo de la Base Lunar, una iniciativa a largo plazo de exploración e infraestructura lunar diseñada para permitir una presencia humana sostenida y ampliar la actividad científica y comercial en la superficie de la Luna.
Como parte de una edad de oro de innovación y exploración, la NASA enviará astronautas en misiones cada vez más difíciles para explorar más de la Luna con fines de descubrimiento científico y beneficios económicos, y para continuar sentando las bases para las primeras misiones tripuladas a Marte.
