The land beneath the New York City area, including the borough of Queens, pictured here, is moving by fractions of inches each year. The motions are a legacy of the ice age and also due to human land usage.

Scientists using space-based radar found that land in New York City is sinking at varying rates from human and natural factors. A few spots are rising.

Parts of the New York City metropolitan area are sinking and rising at different rates due to factors ranging from land-use practices to long-lost glaciers, scientists have found. While the elevation changes seem small – fractions of inches per year – they can enhance or diminish local flood risk linked to sea level rise.

The new study was published Wednesday in Science Advances by a team of researchers from NASA’s Jet Propulsion Laboratory in Southern California and Rutgers University in New Jersey. The team analyzed upward and downward vertical land motion – also known as uplift and subsidence – across the metropolitan area from 2016 to 2023 using a remote sensing technique called interferometric synthetic aperture radar (InSAR). The technique combines two or more 3D observations of the same region to reveal surface motion or topography.

Mapping vertical land motion across the New York City area, researchers found the land sinking (indicated in blue) by about 0.06 inches (1.6 millimeters) per year on average. They also detected modest uplift (shown in red) in Queens and Brooklyn. White dotted lines indicate county/borough borders.

Much of the motion they observed occurred in areas where prior modifications to Earth’s surface – such as land reclamation and the construction of landfills – made the ground looser and more compressible beneath subsequent buildings.

Some of the motion is also caused by natural processes dating back thousands of years to the most recent ice age. About 24,000 years ago, a huge ice sheet spread across most of New England, and a wall of ice more than a mile high covered what is today Albany in upstate New York. Earth’s mantle, somewhat like a flexed mattress, has been slowly readjusting ever since. New York City, which sits on land that was raised just outside the edge of the ice sheet, is now sinking back down.

The scientists found that on average the metropolitan area subsided by about 0.06 inches (1.6 millimeters) per year – about the same amount that a toenail grows in a month. Using the radars on the ESA (European Space Agency) Sentinel-1 satellites, along with advanced data processing techniques, they mapped the motion in detail and pinpointed neighborhoods and landmarks – down to an airport runway and tennis stadium – that are subsiding more rapidly than the average.

The team pinpointed hot spots: left, runway 13/31 at LaGuardia Airport in Queens, is subsiding at a rate of about 0.15 inches (3.7 millimeters) per year; right, part of Newtown Creek, a Superfund site in East Williamsburg, Brooklyn, is rising unevenly by about 0.06 inches (1.6 millimeters) per year.

“We’ve produced such a detailed map of vertical land motion in the New York City area that there are features popping out that haven’t been noticed before,” said lead author Brett Buzzanga, a postdoctoral researcher at JPL.

David Bekaert, a JPL scientist and lead investigator of the project, said that tracking local elevation changes and relative sea level can be important for flood mapping and planning purposes. This is especially critical as Earth’s changing climate pushes oceans higher around the world, leading to more frequent nuisance flood events and exacerbating destructive storm surges.

Local Changes

The team identified two notable hot spots of subsidence co-located with landfills in Queens. One, runway 13/31 at LaGuardia Airport, is subsiding at a rate of about 0.15 inches (3.7 millimeters) per year. The scientists noted that the airport is undergoing an $8 billion renovation designed in part to alleviate flooding from the rising waters of the Atlantic Ocean. They also identified Arthur Ashe Stadium, which is sinking at a rate of about 0.18 inches (4.6 millimeters) per year and required construction of a lightweight roof during renovation to reduce its heaviness and amount of subsidence.

Other subsidence hot spots include the southern portion of Governors Island – built on 38 million square feet (3.5 million cubic meters) of rocks and dirt from early 20th century subway excavations – as well as sites near the ocean in Brooklyn’s Coney Island and Arverne by the Sea in Queens that were built on artificial fill. Similar levels of subsidence were observed beneath Route 440 and Interstate 78 in suburban New Jersey, which traverse historic fill locations, and in Rikers Island, expanded to its present size by landfilling.

The scientists also found previously unidentified uplift in East Williamsburg, Brooklyn – rising by about 0.06 inches (1.6 millimeters) per year – and in Woodside, Queens, which rose 0.27 inches (6.9 millimeters) per year between 2016 and 2019 before stabilizing. Co-author Robert Kopp of Rutgers University said that groundwater pumping and injection wells used to treat polluted water may have played a role, but further investigation is needed. “I’m intrigued by the potential of using high-resolution InSAR to measure these kinds of relatively short-lived environmental modifications associated with uplift,” Kopp said.

The scientists said that cities like New York, which are investing in coastal defenses and infrastructure in the face of sea level rise, can benefit from high-resolution estimates of land motion.

The JPL-led OPERA (Observational Products for End-Users from Remote Sensing Analysis) project will detail surface displacement across North America in a future data product. To do that, it will leverage InSAR data from ESA’s Sentinel-1 and from the upcoming NISAR (NASA-Indian Space Research Organization Synthetic Aperture Radar) mission, set to launch in 2024. Information from OPERA will help scientists better monitor vertical land motion along with other changes connected to natural hazards.

      NASA Study Reveals Venus Crust Surprise
      By NASA

      NASA Study Reveals Venus Crust Surprise
      This global view of the surface of Venus is centered at 180 degrees east longitude. Magellan synthetic aperture radar mosaics from the first cycle of Magellan mapping are mapped onto a computer-simulated globe to create this image. Data gaps are filled with Pioneer Venus Orbiter data, or a constant mid-range value. Simulated color is used to enhance small-scale structure. The simulated hues are based on color images recorded by the Soviet Venera 13 and 14 spacecraft. NASA/JPL-Caltech New details about the crust on Venus include some surprises about the geology of Earth’s hotter twin, according to new NASA-funded research that describes movements of the planet’s crust.
      Scientists expected the outermost layer of Venus’ crust would grow thicker and thicker over time given its apparent lack of forces that would drive the crust back into the planet’s interior. But the paper, published in Nature Communications, proposes a crust metamorphism process based on rock density and melting cycles.
      Earth’s rocky crust is made up of massive plates that slowly move, forming folds and faults in a process known as plate tectonics. For example, when two plates collide, the lighter plate slides on top of the denser one, forcing it downward into the layer beneath it, the mantle. This process, known as subduction, helps control the thickness of Earth’s crust. The rocks making up the bottom plate experience changes caused by increasing temperature and pressure as it sinks deeper into the interior of the planet. Those changes are known as metamorphism, which is one cause of volcanic activity.
      In contrast, Venus has a crust that is all one piece, with no evidence for subduction caused by plate tectonics like on Earth, explained Justin Filiberto, deputy chief of NASA’s Astromaterials Research and Exploration Science Division at NASA’s Johnson Space Center in Houston and a co-author on the paper. The paper used modeling to determine that its crust is about 25 miles (40 kilometers) thick on average and at most 40 miles (65 kilometers) thick.
      “That is surprisingly thin, given conditions on the planet,” said Filiberto. “It turns out that, according to our models, as the crust grows thicker, the bottom of it becomes so dense that it either breaks off and becomes part of the mantle or gets hot enough to melt.” So, while Venus has no moving plates, its crust does experience metamorphism. This finding is an important step toward understanding geological processes and evolution of the planet.
      “This breaking off or melting can put water and elements back into the planet’s interior and help drive volcanic activity,” added Filiberto. “This gives us a new model for how material returns to the interior of the planet and another way to make lava and spur volcanic eruptions. It resets the playing field for how the geology, crust, and atmosphere on Venus work together.”
      The next step, he added, is to gather direct data about Venus’ crust to test and refine these models. Several upcoming missions, including NASA’s DAVINCI (Deep Atmosphere Venus Investigation of Noble gases, Chemistry, and Imaging) and VERITAS (Venus Emissivity, Radio Science, InSAR, Topography, and Spectroscopy) and, in partnership with ESA (European Space Agency), Envision, aim to study the planet’s surface and atmosphere in greater detail. These efforts could help confirm whether processes like metamorphism and recycling are actively shaping the Venusian crust today—and reveal how such activity may be tied to volcanic and atmospheric evolution.
      “We don’t actually know how much volcanic activity is on Venus,” Filiberto said. “We assume there is a lot, and research says there should be, but we’d need more data to know for sure.”

      This six-panel illustration of a tidal disruption event around a supermassive black hole shows the collision with a star followed by an explosion detected in X-ray as well as Hubble Space Telescope visible-light observations. Credits:
      Artwork: NASA, ESA, STScI, Ralf Crawford (STScI) Like a scene out of a sci-fi movie, astronomers using NASA telescopes have found “Space Jaws.”
      Lurking 600 million light-years away, within the inky black depths between stars, there is an invisible monster gulping down any wayward star that plummets toward it. The sneaky black hole betrayed its presence in a newly identified tidal disruption event (TDE) where a hapless star was ripped apart and swallowed in a spectacular burst of radiation. These disruption events are powerful probes of black hole physics, revealing the conditions necessary for launching jets and winds when a black hole is in the midst of consuming a star, and are seen as bright objects by telescopes.
      The new TDE, called AT2024tvd, allowed astronomers to pinpoint a wandering supermassive black hole using NASA’s Hubble Space Telescope, with similar supporting observations from NASA’s Chandra X-Ray Observatory and the NRAO Very Large Array telescope that also showed that the black hole is offset from the center of the galaxy.
      The paper will be published in an upcoming issue of The Astrophysical Journal Letters.
      This six-panel illustration of a tidal disruption event around a supermassive black hole shows the following: 1) A supermassive black hole is adrift inside a galaxy, its presence only detectable by gravitational lensing; 2) A wayward star gets swept up in the black hole’s intense gravitational pull; 3) The star is stretched or “spaghettified” by gravitational tidal effects; 4) The star’s remnants form a disk around the black hole; 5) There is a period of black hole accretion, pouring out radiation across the electromagnetic spectrum, from X-rays to radio wavelengths; and 6) The host galaxy, seen from afar, contains a bright flash of energy that is offset from the galaxy’s nucleus, where an even more massive black hole dwells. Artwork: NASA, ESA, STScI, Ralf Crawford (STScI) Surprisingly, this one million-solar-mass black hole doesn’t reside exactly in the center of the host galaxy, where supermassive black holes are typically found, and actively gobble up surrounding material. Out of approximately 100 TDE events recorded by optical sky surveys so far, this is the first time an offset TDE has been identified. The rest are associated with the central black holes of galaxies.
      In fact, at the center of the host galaxy there is a different supermassive black hole weighing 100 million times the mass of the Sun. Hubble’s optical precision shows the TDE was only 2,600 light-years from the more massive black hole at the galaxy’s center. That’s just one-tenth the distance between our Sun and the Milky Way’s central supermassive black hole.
      This bigger black hole spews out energy as it accretes infalling gas, and it is categorized as an active galactic nucleus. Strangely, the two supermassive black holes co-exist in the same galaxy, but are not gravitationally bound to each other as a binary pair. The smaller black hole may eventually spiral into the galaxy’s center to merge with the bigger black hole. But for now, it is too far separated to be gravitationally bound.
      A TDE happens when an infalling star is stretched or “spaghettified” by a black hole’s immense gravitational tidal forces. The shredded stellar remnants are pulled into a circular orbit around the black hole. This generates shocks and outflows with high temperatures that can be seen in ultraviolet and visible light.
      “AT2024tvd is the first offset TDE captured by optical sky surveys, and it opens up the entire possibility of uncovering this elusive population of wandering black holes with future sky surveys,” said lead study author Yuhan Yao of the University of California at Berkeley. “Right now, theorists haven’t given much attention to offset TDEs. “I think this discovery will motivate scientists to look for more examples of this type of event.”
      This is a Hubble Space Telescope image of distant galaxy that is host to the telltale signature of a roaming supermassive black hole. Science: NASA, ESA, STScI, Yuhan Yao (UC Berkeley); Image Processing: Joseph DePasquale (STScI) A Flash in the Night
      The star-snacking black hole gave itself away when several ground-based sky survey telescopes observed a flare as bright as a supernova. But unlike a supernova, astronomers know that this came from a black hole snacking on a star because the flare was very hot, and showed broad emission lines of hydrogen, helium, carbon, nitrogen, and silicon. The Zwicky Transient Facility at Caltech’s Palomar Observatory, with its 1.2-meter telescope that surveys the entire northern sky every two days, first observed the event.
      “Tidal disruption events hold great promise for illuminating the presence of massive black holes that we would otherwise not be able to detect,” said Ryan Chornock, associate adjunct professor at UC Berkeley and a member of the ZTF team. “Theorists have predicted that a population of massive black holes located away from the centers of galaxies must exist, but now we can use TDEs to find them.”
      The flare was seemingly offset from the center of a bright massive galaxy as cataloged by  Pan-STARRS (Panoramic Survey Telescope and Rapid Response System), the Sloan Digital Sky Survey, and the DESI Legacy Imaging Survey. To better determine that it was not at the galactic center, Yao’s team used NASA’s Chandra X-ray Observatory to confirm that X-rays from the flare site were also offset.
      It took the resolving power of Hubble to settle any uncertainties. Hubble’s sensitivity to ultraviolet light also allows it to pinpoint the location of the TDE, which is much bluer than the rest of the galaxy.
      This is a combined Hubble Space Telescope/Chandra X-Ray Observatory image of a distant galaxy that is host to the telltale signature of a roaming supermassive black hole. Both telescopes caught a tidal disruption event (TDE) caused by the black hole eating a star. Science: NASA, ESA, STScI, Yuhan Yao (UC Berkeley); Image Processing: Joseph DePasquale (STScI) Origin Unknown
      The black hole responsible for the TDE is prowling inside the bulge of the massive galaxy. The black hole only becomes apparent every few tens of thousands of years when it “burps” from capturing a star, and then it goes quiet again until its next meal comes along.
      How did the black hole get off-center? Previous theoretical studies have shown that black holes can be ejected out of the centers of galaxies because of three-body interactions, where the lowest-mass member gets kicked out. This may be the case here, given the stealthy black hole’s close proximity to the central black hole. “If the black hole went through a triple interaction with two other black holes in the galaxy’s core, it can still remain bound to the galaxy, orbiting around the central region,“ said Yao.
      An alternative explanation is that the black hole is the surviving remnant of a smaller galaxy that merged with the host galaxy more than 1 billion years ago. If that is the case, the black hole might eventually spiral in to merge with the central active black hole sometime in the very far future. So at present, astronomers don’t know if it’s coming or going.
      Erica Hammerstein, another UC Berkeley postdoctoral researcher, scrutinized the Hubble images as part of the study, but did not find any evidence of a past galaxy merger. But she explained, “There is already good evidence that galaxy mergers enhance TDE rates, but the presence of a second black hole in AT2024tvd’s host galaxy means that at some point in this galaxy’s past, a merger must have happened.”
      Specialized for different kinds of light, observatories like Hubble and Chandra work together to pinpoint and better understand fleeting events like these. Future telescopes that will also be optimized for capturing transient events like this one include the National Science Foundation’s Vera C. Rubin Observatory and NASA’s upcoming Nancy Grace Roman Space Telescope. They will provide more opportunities for follow-up Hubble observations to zero in on a transient’s exact location.

      The landscape of “mountains” and “valleys” known as the Cosmic Cliffs is actually a portion of the nebula Gum 31, which contains a young star cluster called NGC 3324. Both Gum 31 and NGC 3324 are part of a vast star-forming region known as the Carina Nebula Complex. Credits:
      NASA, ESA, CSA, STScI. In July 2022, NASA’s James Webb Space Telescope made its public debut with a series of breathtaking images. Among them was an ethereal landscape nicknamed the Cosmic Cliffs. This glittering realm of star birth is the subject of a new 3D visualization derived from the Webb data. The visualization, created by NASA’s Universe of Learning and titled “Exploring the Cosmic Cliffs in 3D,” breathes new life into an iconic Webb image.
      It is being presented today at a special event hosted by the International Planetarium Society to commemorate the 100th anniversary of the first public planetarium in Munich, Germany.
      The landscape of “mountains” and “valleys” known as the Cosmic Cliffs is actually a portion of the nebula Gum 31, which contains a young star cluster called NGC 3324. Both Gum 31 and NGC 3324 are part of a vast star-forming region known as the Carina Nebula Complex.
      Ultraviolet light and stellar winds from the stars of NGC 3324 have carved a cavernous area within Gum 31. A portion of this giant bubble is seen above the Cosmic Cliffs. (The star cluster itself is outside this field of view.)
      The Cliffs display a misty appearance, with “steam” that seems to rise from the celestial mountains. In actuality, the wisps are hot, ionized gas and dust streaming away from the nebula under an onslaught of relentless ultraviolet radiation.
      Eagle-eyed viewers may also spot particularly bright, yellow streaks and arcs that represent outflows from young, still-forming stars embedded within the Cosmic Cliffs. The latter part of the visualization sequence swoops past a prominent protostellar jet in the upper right of the image.
      Video: Exploring the Cosmic Cliffs in 3D
      In July 2022, NASA’s James Webb Space Telescope made history, revealing a breathtaking view of a region now nicknamed the Cosmic Cliffs. This glittering landscape, captured in incredible detail, is part of the nebula Gum 31 — a small piece of the vast Carina Nebula Complex — where stars are born amid clouds of gas and dust.
      This visualization brings Webb’s iconic image to life — helping us imagine the true, three-dimensional structure of the universe… and our place within it.
      Produced for NASA by the Space Telescope Science Institute (STScI) with partners at Caltech/IPAC, and developed by the AstroViz Project of NASA’s Universe of Learning, this visualization is part of a longer, narrated video that provides broad audiences, including youth, families, and lifelong learners, with a direct connection to the science and scientists of NASA’s Astrophysics missions. That video enables viewers to explore fundamental questions in science, experience how science is done, and discover the universe for themselves.
      “Bringing this amazing Webb image to life helps the public to comprehend the three-dimensional structure inherent in the 2D image, and to develop a better mental model of the universe,” said STScI’s Frank Summers, principal visualization scientist and leader of the AstroViz Project.
      More visualizations and connections between the science of nebulas and learners can be explored through other products produced by NASA’s Universe of Learning including a Carina Nebula Complex resource page and ViewSpace, a video exhibit that is currently running at almost 200 museums and planetariums across the United States. Visitors can go beyond video to explore the images produced by space telescopes with interactive tools now available for museums and planetariums.
      NASA’s Universe of Learning materials are based upon work supported by NASA under award number NNX16AC65A to the Space Telescope Science Institute, working in partnership with Caltech/IPAC, Center for Astrophysics | Harvard & Smithsonian, and NASA’s Jet Propulsion Laboratory.
      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).

From groundbreaking missions to remarkable technological milestones, Laurie advanced JPL’s legacy of exploration and innovation. We are grateful for her service and wish her the very best as she continues to inspire in the next phase of her career.
      “I’m equally confident in Dave Gallagher’s ability to lead JPL’s next chapter. He brings decades of experience, a steady hand, and a deep understanding of what makes JPL unique. With Dave at the helm, JPL remains well-positioned to continue delivering for NASA and the nation – pushing the boundaries of science and discovery for the benefit of all.”
