A disparate collection of young stellar objects bejewels a cosmic panorama in the star-forming region NGC 1333 in this new image from NASA’s Hubble Space Telescope. To the left, an actively forming star called a protostar casts its glow on the surrounding gas and dust, creating a reflection nebula. Two dark stripes on opposite sides of the bright point (upper left) are its protoplanetary disk, a region where planets could form, and the disk’s shadow, cast across the large envelope of material around the star. Material accumulates onto the protostar through this rotating disk of gas and dust, a product of the collapsing cloud of gas and dust that gave birth to the star. Where the shadow stops and the disk begins is presently unknown.
To the center right, an outflow cavity reveals a fan-shaped reflection nebula. The two stars at its base, HBC 340 (lower) and HBC 341 (upper), unleash stellar winds, or material flowing from the surface of the star, that clear out the cavity from the surrounding molecular cloud over time. A reflection nebula like this one is illuminated by light from nearby stars that is scattered by the surrounding gas and dust.
This reflection nebula fluctuates in brightness over time, which researchers attribute to variations in brightness of HBC 340 and HBC 341. HBC 340 is the primary source of the fluctuation as the brighter and more variable star. HBC 340 and HBC 341 are Orion variable stars, a class of forming stars that change in brightness irregularly and unpredictably, possibly due to stellar flares and ejections of matter from their surfaces. Orion variable stars, so named because they are associated with diffuse nebulae like the Orion Nebula, eventually evolve into non-variable stars.
In this image, the four beaming stars near the bottom of the image and one in the top right corner are also Orion variable stars. The rest of the cloudscape is studded with other young stellar objects.
NGC 1333 lies about 950 light-years away in the Perseus molecular cloud, and was imaged by Hubble to learn more about young stellar objects, such as properties of circumstellar disks and outflows in the gas and dust created by these stars.

NASA’s Webb Delivers Unprecedented Look Into Heart of Circinus Galaxy

The Circinus Galaxy, a galaxy about 13 million light-years away, contains an active supermassive black hole that continues to influence its evolution. The largest source of infrared light from the region closest to the black hole itself was thought to be outflows, or streams of superheated matter that fire outward.

Now, new observations by NASA’s James Webb Space Telescope, seen here with a new image from NASA’s Hubble Space Telescope, provide evidence that reverses this thinking, suggesting that most of the hot, dusty material is actually feeding the central black hole. The technique used to gather this data also has the potential to analyze the outflow and accretion components for other nearby black holes.
The research, which includes the sharpest image of a black hole’s surroundings ever taken by Webb, published Tuesday in Nature.
Outflow question
Supermassive black holes like those in Circinus remain active by consuming surrounding matter. Infalling gas and dust accumulates into a donut-shaped ring around the black hole, known as a torus. As supermassive black holes gather matter from the torus’ inner walls, they form an accretion disk, similar to a whirlpool of water swirling around a drain. This disk grows hotter through friction, eventually becoming hot enough to emit light.
This glowing matter can become so bright that resolving details within the galaxy’s center with ground-based telescopes is difficult. It’s made even harder due to the bright, concealing starlight within Circinus. Further, since the torus is incredibly dense, the inner region of the infalling material, heated by the black hole, is obscured from our point of view. For decades, astronomers contended with these difficulties, designing and improving models of Circinus with as much data as they could gather.

“In order to study the supermassive black hole, despite being unable to resolve it, they had to obtain the total intensity of the inner region of the galaxy over a large wavelength range and then feed that data into models,” said lead author Enrique Lopez-Rodriguez of the University of South Carolina.
Early models would fit the spectra from specific regions, such as the emissions from the torus, those of the accretion disk closest to the black hole, or those from the outflows, each detected at certain wavelengths of light. However, since the region could not be resolved in its entirety, these models left questions at several wavelengths. For example, some telescopes could detect an excess of infrared light, but lacked the resolution to determine where exactly it was coming from.
“Since the ‘90s, it has not been possible to explain excess infrared emissions that come from hot dust at the cores of active galaxies, meaning the models only take into account either the torus or the outflows, but cannot explain that excess,” said Lopez-Rodriguez.
Such models found that most of the emission (and, therefore, mass) close to the center came from outflows. To test this theory, then, astronomers needed two things: the ability to filter the starlight that previously prevented a deeper analysis, and the ability to distinguish the infrared emissions of the torus from those of the outflows. Webb, sensitive and technologically sophisticated enough to meet both challenges, was necessary to advance our understanding.
Webb’s innovative technique
To look into the center of Circinus, Webb needed the Aperture Masking Interferometer tool on its NIRISS (Near-Infrared Imager and Slitless Spectrograph) instrument.
On Earth, interferometers usually take the form of telescope arrays: mirrors or antennae that work together as if they were a single telescope. An interferometer does this by gathering and combining the light from whichever source it is pointed toward, causing the electromagnetic waves that make up light to “interfere” with each other (hence, “interfere-ometer”) and creating interference patterns. These patterns can be analyzed by astronomers to reconstruct the size, shape, and features of distant objects with much greater detail than non-interferometric techniques.
The Aperture Masking Interferometer allows Webb to become an array of smaller telescopes working together as an interferometer, creating these interference patterns by itself. It does this by utilizing a special aperture made of seven small, hexagonal holes, which, like in photography, controls the amount and direction of light that enters the telescope’s detectors.
“These holes in the mask are transformed into small collectors of light that guide the light toward the detector of the camera and create an interference pattern,” said Joel Sanchez-Bermudez, co-author based at the National University of Mexico.
With new data in hand, the research team was able to construct an image from the central region’s interference patterns. To do so, they referenced data from previous observations to ensure their data from Webb was free of any artifacts. This resulted in the first extragalactic observation from an infrared interferometer in space.
“By using an advanced imaging mode of the camera, we can effectively double its resolution over a smaller area of the sky,” Sanchez-Bermudez said. “This allows us to see images twice as sharp. Instead of Webb’s 6.5-meter diameter, it’s like we are observing this region with a 13-meter space telescope.”
The data showed that contrary to the models predicting that the infrared excess comes from the outflows, around 87% of the infrared emissions from hot dust in Circinus come from the areas closest to the black hole, while less than 1% of emissions come from hot dusty outflows. The remaining 12% comes from distances farther away that could not previously be told apart.
“It is the first time a high-contrast mode of Webb has been used to look at an extragalactic source,” said Julien Girard, paper co-author and senior research scientist at the Space Telescope Science Institute. “We hope our work inspires other astronomers to use the Aperture Masking Interferometer mode to study faint, but relatively small, dusty structures in the vicinity of any bright object.”

While the mystery of Circinus’ excess emissions has been solved, there are billions of black holes in our universe. Those of different luminosities, the team notes, may have an influence on whether most of the emissions come from a black hole’s torus or their outflows.
“The intrinsic brightness of Circinus’ accretion disk is very moderate,” Lopez-Rodriguez said. “So it makes sense that the emissions are dominated by the torus. But maybe, for brighter black holes, the emissions are dominated by the outflow.”
With this research, astronomers now have a tested technique to investigate whichever black holes they want, so long as they are bright enough for the Aperture Masking Interferometer to be useful. Studying additional targets will be essential to building a catalog of emission data to figure out if Circinus’ results were unique or characteristic of a pattern.
“We need a statistical sample of black holes, perhaps a dozen or two dozen, to understand how mass in their accretion disks and their outflows relate to their power,” Lopez-Rodriguez said.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

Before and After
Hurricane Melissa made landfall in Jamaica on October 28, 2025, as a category 5 storm, bringing sustained winds of 295 kilometers (185 miles) per hour and leaving a broad path of destruction on the island. The storm displaced tens of thousands of people, damaged or destroyed more than 100,000 structures, inflicted costly damage on farmland, and left the nation’s forests brown and battered.
Prior to landfall, in the waters south of the island, the hurricane created a large-scale natural oceanography experiment. Before encountering land and proceeding north, the monster storm crawled over the Caribbean Sea, churning up the water below. A couple of days later, a break in the clouds revealed what researchers believe could be a once-in-a-century event.
On October 30, 2025, the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument on NASA’s Terra satellite acquired this image (right) of the waters south of Jamaica. Vast areas are colored bright blue by sediment stirred up from a carbonate platform called Pedro Bank. This plateau, submerged under about 25 meters (80 feet) of water, is slightly larger in area than the state of Delaware. For comparison, the left image was acquired by the same sensor on September 20, before the storm.
Pedro Bank is deep enough that it is only faintly visible in natural color satellite images most of the time. However, with enough disruption from hurricanes or strong cold fronts, its existence becomes more evident to satellites. Suspended calcium carbonate (CaCO3) mud, consisting primarily of remnants of marine organisms that live on the plateau, turns the water a Maya blue color. The appearance of this type of material contrasts with the greenish-brown color of sediment carried out to sea by swollen rivers on Jamaica’s southern coast.
As an intense storm that lingered in the vicinity of the bank, Hurricane Melissa generated “tremendous stirring power” in the water column, said James Acker, a data support scientist at the NASA Goddard Earth Sciences Data and Information Services Center with a particular interest in these events. Hurricane Beryl caused some brightening around Pedro Bank in July 2024, “but nothing like this,” he said. “While we always have to acknowledge the human cost of a disaster, this is an extraordinary geophysical image.”
Sediment suspension was visible on Pedro and other nearby shallow banks, indicating that Melissa affected a total area of about 37,500 square kilometers—more than three times the area of Jamaica—on October 30, said sedimentologist Jude Wilber, who tracked the plume’s progression using multiple satellite sensors. Having studied carbonate sediment transport for decades, he believes the Pedro Bank event was the largest observed in the satellite era. “It was extraordinary to see the sediment dispersed over such a large area,” he said.
The sediment acted as a tracer, illuminating currents and eddies near the surface. Some extended into the flow field of the Caribbean Current heading west and north, while other patterns suggested the influence of Ekman transport, Wilber said. The scientists also noted complexities in the south-flowing plume, which divided into three parts after encountering several small reefs. Sinking sediment in the easternmost arm exhibited a cascading stair-step pattern.
Like in other resuspension events, the temporary coloration of the water faded after about seven days as sediment settled. But changes to Pedro Bank itself may be more long-lasting. “I suspect this hurricane was so strong that it produced what I would call a ‘wipe’ of the benthic ecosystem,” Wilber said. Seagrasses, algae, and other organisms living on and around the bank were likely decimated, and it is unknown how repopulation of the area will unfold.
Sediments from the top of Pedro Bank contain masses of calcified red algae, flaky sands made of Halimeda macroalgae remnants, and carbonate mud. The wing-like shape of Halimeda sand allows it to be lifted and transported while waters are turbulent, and finer mud remains suspended longer. These samples were acquired during a research expedition in the winter of 1987-1988 and are archived at the Woods Hole Oceanographic Institution.

Perhaps most consequentially for Earth’s oceans, however, is the effect of the sediment suspension event on the planet’s carbon cycle. Tropical cyclones are an important way for carbon in shallow-water marine sediments to reach deeper waters, where it can remain sequestered for the long term. At depth, carbonate sediments will also dissolve, another important process in the oceanic carbon system.
Near-continuous ocean observations by satellites have enabled greater understanding of these events and their carbon cycling. Acker and Wilber have worked on remote-sensing methods to quantify how much sediment reaches the deep ocean following the turbulence of tropical cyclones, including recently with Hurricane Ian over the West Florida Shelf. Now, hyperspectral observations from NASA’s PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission, launched in February 2024, are poised to build on that progress, Acker said.
The phenomenon at Pedro Bank following Hurricane Melissa provided a singular opportunity to study this and other complex ocean processes—a large natural experiment that could not be accomplished any other way. Researchers will be further investigating a range of physical, geochemical, and biological aspects illuminated by this occurrence. As Wilber put it: “This event is a whole course in oceanography.”

A Quarter Century in Orbit: Science Shaping Life on Earth and Beyond
For more than 25 years, humans have lived and worked continuously aboard the International Space Station, conducting research that is transforming life on Earth and shaping the future of exploration. From growing food and sequencing DNA to studying disease and simulating Mars missions, every experiment aboard the orbiting laboratory expands our understanding of how humans can thrive beyond Earth while advancing science and technology that benefit people around the world.
Unlocking new cancer therapies from space

NASA
The space station gives scientists a laboratory unlike any on Earth. In microgravity, cells grow in three dimensions, proteins form higher-quality crystals, and biological systems reveal details hidden by gravity. These conditions open new ways to study disease and develop treatments.
Astronauts and researchers have used the orbiting laboratory to observe how cancer cells grow, test drug delivery methods, and examine protein structures linked to diseases such as Parkinson’s and Alzheimer’s. One example is the Angiex Cancer Therapy study, which tested a drug designed to target blood vessels that feed tumors. In microgravity, endothelial cells survive longer and behave more like they do in the human body, giving researchers a clearer view of how the therapy works and whether it is safe before human trials.
Protein crystal growth (PCG) is another major area of cancer-related study. The NanoRacks-PCG Therapeutic Discovery and On-Orbit Crystals investigations have advanced research on leukemia, breast cancer, and skin cancers. Protein crystals grown in microgravity produce larger, better-organized structures that allow scientists to determine fine structural details that guide the design of targeted treatments.
Studies in orbit have also provided insights about cardiovascular health, bone disorders, and how the immune system changes in space—knowledge that informs medicine on Earth and prepares astronauts for long missions in deep space.
By turning space into a research lab, scientists are advancing therapies that benefit people on Earth and laying the foundation for ensuring crew health on future journeys to the Moon and Mars.
Farming for the future
NASA astronauts Jessica Watkins and Bob Hines work on the eXposed Root On-Orbit Test System (XROOTS) space botany investigation, which used the station’s Veggie facility to test soilless hydroponic and aeroponic methods to grow plants. The space agricultural study could enable production of crops on a larger scale to sustain crews on future space explorations farther away from Earth.
NASA
Feeding astronauts on long-duration missions requires more than packaged meals. It demands sustainable systems that can grow fresh food in space. The Vegetable Production System, known as Veggie, is a garden on the space station designed to test how plants grow in microgravity while adding fresh produce to the crew’s diet and improving well-being in orbit.
To date, Veggie has produced three types of lettuce, Chinese cabbage, mizuna mustard, red Russian kale, and even zinnia flowers. Astronauts have eaten space-grown lettuce, mustard greens, radishes, and chili peppers using Veggie and the Advanced Plant Habitat, a larger, more controlled growth chamber that allows scientists to study crops in greater detail.
These plant experiments pave the way for future lunar and Martian greenhouses by showing how microgravity affects plant development, water and nutrient delivery, and microbial interactions. They also provide immediate benefits for Earth, advancing controlled-environment agriculture and vertical farming techniques that help make food production more efficient and resilient in challenging environments.
First year-long twin study

Understanding how the human body changes in space is critical for planning long-duration missions. NASA’s Twins Study offered an unprecedented opportunity to investigate nature vs. nurture in orbit and on Earth. NASA astronaut Scott Kelly spent nearly a year aboard the space station while his identical twin, retired astronaut Mark Kelly, remained on Earth.
By comparing the twins before, during, and after the mission, researchers examined changes at the genomic, physiological, and behavioral levels in one integrated study. The results showed most changes in Scott’s body returned to baseline after his return, but some persisted—such as shifts in gene expression, telomere length, and immune system responses.
The study provided the most comprehensive molecular view to date of how a human body adapts to spaceflight. Its findings may guide NASA’s Human Research Program for years to come, informing countermeasures for radiation, microgravity, and isolation. The research may have implications for health on Earth as well—from understanding aging and disease to exploring treatments for stress-related disorders and traumatic brain injury.
The Twins Study demonstrated the resilience of the human body in space and continues to shape the medical playbook for the Artemis campaign to the Moon and future journeys to Mars.
Simulating deep space

The space station, which is itself an analog for deep space, complements Earth-based analog research simulating the spaceflight environment. Space station observations, findings, and challenges, inform the research questions and countermeasures scientists explore on Earth.
Such work is currently underway through CHAPEA (Crew Health and Performance Exploration Analog), a mission in which volunteers live and work inside a 1,700-square-foot, 3D-printed Mars habitat for about a year. The first CHAPEA crew completed 378 days in isolation in 2024, testing strategies for maintaining health, growing food, and sustaining morale under delayed communication.
NASA recently launched CHAPEA 2, with a four-person crew who began their 378-day simulated Mars mission at Johnson on October 19, 2025. Building on lessons from the first mission and decades of space station research, they will test new technologies and behavioral countermeasures that will help future explorers thrive during long-duration missions, preparing Artemis astronauts for the journey to the Moon and laying the foundation for the first human expeditions to Mars.
Keeping crews healthy in low Earth orbit

NASA
Staying healthy is a top priority for all NASA astronauts, but it is particularly important while living and working aboard the orbiting laboratory.
Crews often spend extended periods of time aboard the orbiting laboratory, with the average mission lasting about six months or more. During these long-duration missions, without the continuous load of Earth’s gravity, there are many changes to the human body. Proper nutrition and exercise are some of the ways these effects may be mitigated.
NASA has a team of medical physicians, psychologists, nutritionists, exercise scientists, and other specialized medical personnel who collaborate to ensure astronauts’ health and fitness on the station. These teams are led by a NASA flight surgeon, who regularly monitors each crew member’s health during a mission and individualizes diet and fitness routines to prioritize health and safety while in space.
Crew members are also part of the ongoing health and performance research being conducted to advance understanding of long-term spaceflight’s effects on the human body. That knowledge is applied to any crewed mission and will help prepare humanity to travel farther than ever before, including the Moon and Mars.
Sequencing the future
NASA astronaut Kate Rubins checks a sample for air bubbles prior to loading it in the biomolecule sequencer. When Rubins’ expedition began, zero base pairs of DNA had been sequenced in space. Within just a few weeks, she and the Biomolecule Sequencer team had sequenced their one billionth base of DNA aboard the orbiting laboratory.
In 2016, NASA astronaut Kate Rubins made history aboard the orbital outpost as the first person to sequence DNA in space. Using a handheld device called the MinION, she analyzed DNA samples in microgravity, proving that genetic sequencing could be performed in low Earth orbit for the first time.
Her work advanced in-flight molecular diagnostics, long-duration cell culture, and molecular biology techniques such as liquid handling in microgravity.
The ability to sequence DNA aboard the orbiting laboratory allows astronauts and scientists to identify microbes in real time, monitor crew health, and study how living organisms adapt to spaceflight. The same technology now supports medical diagnostics and disease detection in remote or extreme environments on Earth.
This research continues through the Genes in Space program, where students design DNA experiments that fly aboard NASA missions. Each investigation builds on Rubins’ milestone, paving the way for future explorers to diagnose illness, monitor environmental health, and search for signs of life beyond Earth.
