EBANI stands for "Unidentified Anomalous Biological Entity," referring to a mysterious class of airborne phenomena that may be biological rather than mechanical in nature. These entities are often described as elongated, flexible, and tubular, moving through the sky in a serpentine or twisting manner.
They exhibit advanced flight capabilities, including high-speed travel, precise control, and even self-illumination. Some have been observed rendering themselves invisible, raising questions about their energy sources and possible technological origins.
Recent observations have revealed formations of translucent spheres in red, white, and blue, challenging conventional classifications of both biology and aerodynamics.
Some of these entities have a massive structure composed of thousands of clustered spheres. These entities appear to function as an aircraft carrier, releasing these smaller spheres into Earth's atmosphere for an unknown purpose.
While some researchers propose that EBANIs are natural organisms evolving in Earth's upper atmosphere under unfamiliar physical laws, others speculate they may be advanced artificial (eventually biological) constructs, potentially extraterrestrial probes or surveillance devices, given the presence of large structures expelling numerous smaller spheres.
Are they living UFOs, advanced biological organisms that function autonomously within the spheres, without the need for pilots?

Sols 4471-4472: Marching Through the Canyon
NASA’s Mars rover Curiosity acquired this image using its Mast Camera (Mastcam), a close-up of the rover’s Alpha Particle X-Ray Spectrometer (APXS), an instrument that measures the abundance of chemical elements in rocks and soils on the Martian surface. Located on the turret at the end of Curiosity’s robotic arm, APXS is about the size of a cupcake, and this image shows the handwritten markings on the instrument’s sensor head. Curiosity captured this image on March 23, 2024 — sol 4134, or Martian day 4,134 of the Mars Science Laboratory mission — at 21:59:21 UTC.

Earth planning date: Monday, March 3, 2025
Curiosity continued steady progress through the upper sulfate unit and toward its next major science waypoint: the boxwork structures. Our rover is currently driving south through a local canyon between “Texoli” and “Gould Mesa.” This route may expose the same rock layers observed while climbing along the eastern margin of the Gediz Vallis channel, prompting several science activities in today’s plan. With winter still gripping Gale crater and limiting the power available for science, the team carefully balanced a number of priorities.
The weekend’s drive positioned the rover within reach of light-toned laminated bedrock and gray float rock. We kicked off our two-sol plan by removing dust on a representative bedrock target, “Ramona Trail,” before analyzing with APXS and imaging with MAHLI. ChemCam acquired compositional analyses on a laminated gray float rock, “Josephine Peak,” in addition to long-distance images of Texoli. Mastcam documented key features, capturing images of Josephine Peak, Texoli, “Gobblers Knob,” and “Fort Tejon.” In addition to these science-driven images, Mastcam also acquired two images of APXS before a planned drive of about 21 meters (about 69 feet).
As Curiosity continues toward the boxwork structures, the intricate patterns we observe will provide valuable clues about the history of Mars. While the Mastcam images acquired today of the APXS sensor head won’t directly contribute to the boxwork study, they capture a more human aspect of the mission. With each “APXS horseshoe” image, such as the one featured in this blog from sol 4134, hand-written markings on the APXS sensor head appear alongside Martian terrain, a reminder that this incredible journey is driven by the human touch of a dedicated team on Earth who designed, built, and continue to operate this remarkable spacecraft.

Greg Shirah/NASA’s Scientific Visualization Studio Historically, the ocean has been difficult to model. Scientists struggled in years past to simulate ocean currents or accurately predict fluctuations in temperature, salinity, and other properties. As a result, models of ocean dynamics rapidly diverged from reality, which meant they could only provide useful information for brief periods.
In 1999, a project called Estimating the Circulation and Climate of the Ocean (ECCO) changed all that. By applying the laws of physics to data from multiple satellites and thousands of floating sensors, NASA scientists and their collaborators built ECCO to be a realistic, detailed, and continuous ocean model that spans decades. ECCO enabled thousands of scientific discoveries, and was featured during the announcement of the Nobel Prize for Physics in 2021.
NASA ECCO is a powerful integrator of decades of ocean data, narrating the story of Earth’s changing ocean as it drives our weather, and sustains marine life.
The ECCO project includes hundreds of millions of real-world measurements of temperature, salinity, sea ice concentration, pressure, water height, and flow in the world’s oceans. Researchers rely on the model output to study ocean dynamics and to keep tabs on conditions that are crucial for ecosystems and weather patterns. The modeling effort is supported by NASA’s Earth science programs and by the international ECCO consortium, which includes researchers from NASA’s Jet Propulsion Laboratory in Southern California and eight research institutions and universities.
The project provides models that are the best possible reconstruction of the past 30 years of the global ocean. It allows us to understand the ocean’s physical processes at scales that are not normally observable.
ECCO and the Western Boundary Currents
Western boundary currents stand out in white in this visualization built with ECCO data. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio Large-scale wind patterns around the globe drag ocean surface waters with them, creating complex currents, including some that flow toward the western sides of the ocean basins. The currents hug the eastern coasts of continents as they head north or south from the equator: These are the western boundary currents. The three most prominent are the Gulf Stream, Agulhas, and Kuroshio. NASA Goddard’s Scientific Visualization Studio.
The North American Gulf Stream as illustrated with the ECCO model. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio Seafarers have known about the Gulf Stream — the Atlantic Ocean’s western boundary current — for more than 500 years. By the volume of water it moves, the Gulf Stream is the largest of the western boundary currents, transporting more water than all the planet’s rivers combined.
In 1785, Benjamin Franklin added it to maritime charts showing the current flowing up from the Gulf, along the eastern U.S. coast, and out across the North Atlantic. Franklin noted that riding the current could improve a ship’s travel time from the Americas to Europe, while avoiding the current could shorten travel times when sailing back.
A visualization built of ECCO data reveals a cold, deep countercurrent that flows in the opposite direction of the warm Gulf Stream above it. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio Franklin’s charts showed a smooth Gulf Stream rather than the twisted, swirling path revealed in ECCO data. And Franklin couldn’t have imagined the opposing flow of water below the Gulf Stream. The countercurrent runs at depths of about 2,000 feet (600 meters) in a cold river of water that is roughly the opposite of the warm Gulf Stream at the surface. The submarine countercurrent is clearly visible when the upper layers in the ECCO model are peeled away in visualizations.
The Gulf Stream is a part of the Atlantic Meridional Overturning Circulation (AMOC), which moderates climate worldwide by transporting warm surface waters north and cool underwater currents south. The Gulf Stream, in particular, stabilizes temperatures of the southeastern United States, keeping the region warmer in winter and cooler in summer than it would be without the current. After the Gulf Stream crosses the Atlantic, it tempers the climates of England and the European coast as well.
The Agulhas current originates along the equator in the Indian Ocean, travels down the western coast of Africa, and spawns swirling Agulhas rings that travel across the Atlantic toward South America. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio The Agulhas Current flows south along the western side of the Indian Ocean. When it reaches the southern tip of Africa, it sheds swirling vortices of water called Agulhas Rings. Sometimes persisting for years, the rings glide across the Atlantic toward South America, transporting small fish, larvae, and other microorganisms from the Indian Ocean.
Researchers using the ECCO model can study Agulhas Current flow as it sends warm, salty water from the tropics in the Indian Ocean toward the tip of South Africa. The model helps tease out the complicated dynamics that create the Agulhas rings and large loop of current called a supergyre that surrounds the Antarctic. The Southern Hemisphere supergyre links the southern portions of other, smaller current loops (gyres) that circulate in the southern Atlantic, Pacific, and Indian oceans. Together with gyres in the northern Atlantic and Pacific, the southern gyres and Southern Hemisphere supergyre influence climate while transporting carbon around the globe.
The Kuroshio Current flows on the western side of the Pacific Ocean, past the east coast of Japan, east across the Pacific, and north toward the Arctic. Along the way, it provides warm water to drive seasonal storms, while also creating ocean upwellings that carry nutrients that sustain fisheries off the coasts of Taiwan and northern Japan. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio In addition to affecting global weather patterns and temperatures, western boundary currents can drive vertical flows in the oceans known as upwellings. The flows bring nutrients up from the depths to the surface, where they act as fertilizer for phytoplankton, algae, and aquatic plants.
The Kuroshio Current that runs on the west side of the Pacific Ocean and along the east side of Japan has recently been associated with upwellings that enrich coastal fishing waters. The specific mechanisms that cause the vertical flows are not entirely clear. Ocean scientists are now turning to ECCO to tease out the connection between nutrient transport and currents like the Kuroshio that might be revealed in studies of the water temperature, density, pressure, and other factors included in the ECCO model.
Tracking Ocean Temperatures and Salinity
When viewed through the lens of ECCO’s temperature data, western boundary currents carry warm water away from the tropics and toward the poles. In the case of the Gulf Stream, as the current moves to far northern latitudes, some of the saltwater freezes into salt-free sea ice. The saltier water left behind sinks and then flows south all the way toward the Antarctic before rising and warming in other ocean basins.
Colors indicate temperature in this visualization of ECCO data. Warm water near the equator is bright yellow. Water cools when it flows toward the poles, indicated by the transition to orange and red shades farther from the equator. Download this visualization from NASA Goddard’s Scientific Visualization Studio. Credits: Greg Shirah/NASA’s Scientific Visualization Studio Currents also move nutrients and salt throughout Earth’s ocean basins. Swirling vortexes of the Agulhas rings stand out in ECCO temperature and salinity maps as they move warm, salty water from the Indian Ocean into the Atlantic.
The Mediterranean Sea has a dark red hue that indicates its high salt content. Other than the flow through the narrow Strait of Gibraltar, the Mediterranean is cut off from the rest of the world’s oceans. Because of this restricted flow, salinity increases in the Mediterranean as its waters warm and evaporate, making it one of the saltiest parts of the global ocean.

ECCO offers researchers a way to run virtual experiments that would be impractical or too costly to perform in real oceans. Some of the most important applications of the ECCO model are in ocean ecology, biology, and chemistry. Because the model shows where the water comes from and where it goes, researchers can see how currents transport heat, minerals, nutrients, and organisms around the planet.
In prior decades, for example, ocean scientists relied on extensive temperature and salinity measurements by floating sensors to deduce that the Gulf Stream is primarily made of water flowing past the Gulf rather than through it. The studies were time-consuming and expensive. With the ECCO model, data visualizers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, virtually replicated the research in a simulation that was far quicker and cheaper.
A simulation built with data from the ECCO model shows that very little of the water in the gulf contributes to the water flowing in the Gulf Stream.

Credits: Atousa Saberi/NASA’s Scientific Visualization Studio The example illustrated here relies on ECCO to track the flow of water by virtually filling the Gulf with 115,000 particles and letting them move for a year in the model. The demonstration showed that less than 1% of the particles escape the Gulf to join the Gulf Stream.
Running such particle-tracking experiments within the ocean circulation models helps scientists understand how and where environmental contaminants, such as oil spills, can spread.
Take an ECCO Deep Dive
Today, researchers turn to ECCO for a broad array of studies. They can choose ECCO modeling products that focus on one feature – such as global flows or the biology and chemistry of the ocean – or they can narrow the view to the poles or specific ocean regions. Every year, more than a hundred scientific papers include data and analyses from the ECCO model that delve into our oceans’ properties and dynamics.

Portrait of John Boyd, whose contributions to NASA spanned more than 70 years.Credit: NASA John Boyd, known to many as Jack and whose career spanned more than seven decades in a multitude of roles across NASA as well as its predecessor, the National Advisory Committee for Aeronautics (NACA), died Feb. 20. He was 99. Born in 1925, and raised in Danville, Virginia, he was a long-time resident of Saratoga, California.
Boyd is being remembered by many across the agency, including Dr. Eugene Tu, director, NASA’s Ames Research Center in California’s Silicon Valley, where Boyd spent most of his career.
“Jack brought an energy, optimism, and team-based approach to solving some of the greatest technological challenges humanity has ever faced, which remains part of our culture to this day,” said Tu. “There are few careers as wide-ranging and impactful as Jack’s.”
In 1947, Boyd began his career at the then-called Ames Aeronautical Laboratory in Moffett Field, California, as an aeronautical engineer working to design and test various wing shapes using the center’s 1-by-3-foot supersonic wind tunnel. Boyd continued conducting research in wind tunnels, testing designs that led to dramatic increases in the efficiency of the supersonic B-58 bomber, as well as the F-102 and F-106 fighters.
In 1958, just before Ames became part of a newly established NASA, Boyd recalled thinking, “Maybe someday we’ll go out into the far blue yonder, and if we do, what are we going to fly? How are we going to bring it back into the atmosphere safely?” He and a team of engineers turned their attention to studying the dynamics of high-speed projectiles in hypervelocity ranges, filled with different mixtures of gases to mimic the atmospheres of Mars and Venus, in preparation for sending spacecraft out into space and safely back again or to the surface of other worlds.
By the mid-60s, Boyd was promoted into leadership and tapped to become deputy director for Aeronautics and Flight Systems at NASA Ames. In the late 1960s, as America was redefining its space exploration goals and sending humans to the Moon, Boyd served as the center’s lead to assist NASA Headquarters in Washington consolidate and create new research programs.
In 1979, Boyd served as the deputy director at NASA’s Dryden Flight Research Center (now known as NASA’s Armstrong Flight Research Center) in Edwards, California, and prepared the center for its role as a landing site for the space shuttle. He briefly returned to Ames before heading to NASA Headquarters to be associate administrator for management under James M. Beggs. Boyd left government service in 1985, taking a position as chancellor for research and an adjunct professor of aerodynamics, engineering, and the history of spaceflight for the University of Texas System.
Boyd returned to NASA and California’s Silicon Valley in 1993,inspiring students through educational outreach initiatives, and serving as the senior advisor to the director, senior advisor for history, and the center ombudsman until his retirement in 2020.
Boyd credits his interest in airplanes to a cousin who was a paratrooper and gave him a ride in a biplane in the 1940s. In 1943, he enrolled and became the first in his family to earn a degree with a bachelor of science in aeronautical engineering from Virginia Polytechnic Institute and State University in Blacksburg, Virginia. He was a recipient of the NASA Exceptional Service Award, the NASA Outstanding Leadership Award, the NASA Equal Employment Opportunity Medal, the Presidential Rank of Meritorious Executive, the NASA Distinguished Service Medal, the Army Command Medal, and the NASA Headquarters History Award. He also was a Fellow of the American Institute of Aeronautics and Astronautics and a Sloan Fellow at Stanford University.
“The agency and the nation thank and honor Jack as a member of the NASA family and the highest exemplar of a public servant who believed investing in others is the greatest contribution one can make,” added Tu. “He will be deeply missed.”
