Sea level data from a satellite launched by NASA and European partners shows that a swell of warm water hundreds of miles wide has arrived in the Pacific Ocean off the coast of South America, a sign that El Niño will likely emerge later in the year. Because water expands as it warms, a rise in elevation of an area of the ocean indicates increasing ocean temperatures.
El Niños can cause heavy precipitation in some regions and deficits in others, influencing daily life and commerce around the world.
Launched in 2020 by NASA and led by ESA (European Space Agency) for the E.U. Copernicus Programme, the Sentinel-6 Michael Freilich satellite measures and maps water height for the entire ocean every 10 days, down to fractions of an inch. In the case of El Niño, the satellite tracks what are called warm Kelvin waves.
These waves typically form after brief periods when winds over the far western equatorial Pacific Ocean shift from prevailing easterlies — moving from east to west — to westerlies. That effect, combined with a general weakening of easterly winds along the equator, causes water in the tropics of the western Pacific to get warmer and sea levels to rise. The wave that forms then propagates east for several weeks, eventually reaching South America and causing water off the coast to heat up and rise. An El Niño develops as multiple Kelvin waves appear over the course of several months, and the warm water accumulates off the shores of Colombia, Ecuador, and Peru.
“While this year’s event started a bit later than the big El Niños of 2015 and 1997, it’s beginning to catch up,” said Josh Willis, a sea level researcher at NASA’s Jet Propulsion Laboratory in Southern California and project scientist for Sentinel-6 Michael Freilich. “We’ll see how big it gets.”
Measurements from Sentinel-6 Michael Freilich show a small Kelvin wave forming around Micronesia in late January and dissipating by mid-February. A new wave emerged in early March, then moved east over time. By mid-May, the seas around Peru were more than 5.9 inches (15 centimeters) higherthan long-term averages.
“NASA’s observation of El Niño uses sea level satellites like Sentinel-6 Michael Freilich to track massive Kelvin waves as they cross the Pacific, capture changes in Earth’s ocean thermodynamics, improve forecasts of weather extremes, and help communities prepare for potential coastal hazards,” said Nadya Vinogradova Shiffer, lead program scientist at NASA Headquarters in Washington. “Stay tuned as more ocean stories continue to unfold.”
Fishermen in the 1600s coined the name El Niño — Spanish for “the boy,” a reference to the birth of baby Jesus — because it tended to intensify around Christmastime. Warmer waters meant they would catch fewer fish.
Warmer sea surface temperatures in the central and eastern Pacific affect atmospheric circulation patterns worldwide by shifting the jet stream, which impacts storm tracks. This can lead to heavy rain and snow in some areas and unusual heat and dryness in others. How far away those impacts appear depends on the strength of the El Niño.
In more modest events, like the ones that began in 2018 and 2023, impacts such as drought and flooding were mostly seeb in and around the tropical Pacific. Large El Niños, like the one in 2015-2016, reach much farther, causing drought in Africa and flooding in California.
El Niños usually peak between November and January, so it will be several months before the largest impacts become clear.
“Every El Niño is different,” said JPL sea level researcher Severine Fournier, deputy project scientist for Sentinel-6 Michael Freilich. “But they almost always make for a hot year and big changes in rainfall in parts of the globe.”
Sentinel-6 Michael Freilich is the current official reference satellite for global sea level measurements. Launched in 2020, it is continuing a legacy started in 1992 by the TOPEX/Poseidon satellite. A series of successors have carried the baton since then, and the latest, Sentinel-6B, which launched November 2025, will take over for its predecessor by the end of 2026.
Sentinel-6 Michael Freilich, named after former NASA Earth Science Division Director Michael Freilich, is one of two satellites that compose the Copernicus Sentinel-6/Jason-CS (Continuity of Service) mission.
Sentinel-6/Jason-CS, a part of the European Union’s Earth observation programme called Copernicus, was jointly developed by ESA, the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), NASA, and the National Oceanic and Atmospheric Administration (NOAA), with funding support from the European Commission and technical support on performance from the French space agency CNES (Centre National d’Études Spatiales). Spacecraft monitoring and control, as well as the processing of all the altimeter science data, is carried out by EUMETSAT on behalf of the European Union’s Copernicus Programme, with the support of all partner agencies.
A division of Caltech in Pasadena, JPL contributed three science instruments for each Sentinel-6 satellite: the Advanced Microwave Radiometer, the Global Navigation Satellite System – Radio Occultation, and the Laser Retroreflector Array. NASA also contributed launch services, ground systems supporting operation of the NASA science instruments, the science data processors for two of these instruments, and support for the U.S. members of the international Ocean Surface Topography Science Team.

Which comes first, the galaxy or the black hole? We don’t know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can gobble up surrounding material and merge over time to form more massive entities.
But it’s hard to figure out how black holes millions to billions of times the mass of the Sun, thousands of which have now been detected in the early universe, could have grown so quickly from such small seeds.
Now, researchers using NASA’s James Webb Space Telescope have detected clear evidence that some supermassive black holes were enormous from the beginning, forming without a stellar collapse phase, and without a significantly more massive host galaxy to feed them.
“This is a remarkable finding,” said Roberto Maiolino of University of Cambridge in the United Kingdom, co-author of studies published in Nature and the Monthly Notices of the Royal Astronomical Society. “It’s a paradigm shift, a total revisiting of the classical scenarios of how black holes form and grow.”
The team’s conclusion is based on detailed observations of Abell2744-QSO1 (QSO1), a prototypical Little Red Dot that existed just 700 million years after the big bang.
Although QSO1 is only 1,300 light-years across, and its light has been traveling for more than 13 billion years, it is easier to study than most other Little Red Dots because it is gravitationally lensed by galaxy cluster Abell 2744 (Pandora’s Cluster). QSO1 is both magnified and triply imaged, appearing in three different locations in the sky.
Initial studies of QSO1 revealed compelling evidence that it may be little more than a cloud of glowing hydrogen and helium gas circling a supermassive black hole estimated at 40 million times the mass of the Sun. But as with other early black holes discovered by Webb, there was uncertainty about whether it really was that massive.
“Before now, all of the mass measurements of black holes in the early universe have been indirect, based on assumptions from what we know about them in the local universe. We didn’t know if those assumptions really apply to the distant universe,” said co-author Francesco D’Eugenio, also of the University of Cambridge.
The team recognized that if QSO1’s black hole is as massive as it looks, they should be able to use the integral field unit (IFU) on Webb’s NIRSpec (Near Infrared Spectrograph) to trace the effects of its gravity on the gas swirling around it, while also mapping the distribution of various elements in the gas.
Cambridge graduate student Ignas Juodžbalis and Cosimo Marconcini of the University of Florence, lead authors on one of the studies, used the IFU observations to map motions of hydrogen gas surrounding the black hole. When they plotted the rotation velocity as a function of distance from the center, they found that the gas has Keplerian motion: It orbits a central point in the same way that planets in our solar system orbit the Sun.
“This is important because it tells us that most of the mass of QSO1 is concentrated in the black hole at the center,” said Juodžbalis. “If the mass were more distributed, as it would be if there were a lot of stars, the gas would not have this perfect Keplerian rotation.”
Since Keplerian motion is governed by simple laws of gravity, the team was able to use the gas velocity measurements to calculate the black hole mass directly, a feat that had not previously been possible.
They found that not only is the black hole immense — roughly 50 million solar masses — it makes up, at minimum, an astonishing two-thirds of QSO1’s total mass. This proportion is thousands of times greater than in nearby galaxies, where supermassive black holes make up only a tiny fraction of the host galaxy’s total mass.
The IFU composition maps supported these results, showing that the gas throughout QSO1 is almost entirely hydrogen and helium, with very little of the heavier elements like oxygen that would be expected in a galaxy rich with stars and stellar debris. With a metallicity less than 0.5% of the Sun, QSO1 is one of the most pristine galactic environments ever measured.
“This is a phenomenal result,” said Maiolino. “It is the first direct measurement of a black hole mass within the first billion years after the big bang, and it is consistent with the previous measurements.” The team thinks this is a good sign that the assumptions used for indirect mass measurements are valid and the masses of other black holes in the early universe have not been overestimated.
The outsized mass of QSO1 relative to its host galaxy suggests that it can’t have formed gradually from much smaller, stellar-mass black holes merging and feeding. “It seems that we have found a black hole that does not have a substantial host galaxy and that has predated stellar processes,” said Juodžbalis. “This is very exciting because it is evidence for primordial black holes or direct collapse black holes, which have been theorized but not confirmed.”
Whether QSO1’s black hole evolved from a “heavy seed” that formed within the first second of the big bang or somewhat later from the collapse of a giant cloud of gas, it was almost certainly born big, and may be in the early stages of building a galaxy around it.
The team thinks that Little Red Dots like QSO1 cannot have been rare in the early universe, and is in the process of analyzing similar objects to find out whether supermassive black holes actually do predate the galaxies where they currently reside.
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).
