People reported earthquakes and fire in the sky. It was probably a meteor.
The fireball is presumed to be from a meteor fragmenting in the sky, according to meteorologists and other experts. People in the southeastern United States on Thursday, June 26, reported a fireball in the sky and rumbling on the ground, an unsettling combination that was probably a meteor, according to various agencies. Reports of sightings flooded the American Meteor Society around 12:30 p.m. And the National Weather Service in Peachtree City, Georgia, said residents reported what felt like earthquakes around that time. Bill Cooke, the chief of NASA's Meteoroid Environments Office at the agency's Marshall Space Flight Center in Huntsville, Alabama, told The New York Times and local news outlets that the flying space rock was about three feet in diameter and weighed more than one ton. (The USA TODAY Network left a message with the Marshall Space Flight Center seeking more information.) And the earthquake reports? Those were likely sonic booms, the brief, thunder-like noises when a spacecraft, aircraft or space rocks travel faster than the speed of sound, the local weather service office said. The awesome sight likely wasn't entirely harmless: Remnants of the cosmic object may have broken off and plummeted through the roof of a home in Henry County, Georgia, according to the local National Weather Service office. Did a meteor crash into a Georgia home? Did you feel that today? Many in north Georgia not only felt it but saw it. It appears that either a meteor or space... The weather service, citing the Henry County Emergency Management agency, said a resident south of Atlanta reported that a "rock" fell through their roof, broke through the ceiling and cracked the home's laminate flooring. Because the incident occurred around the time sightings were happening, "we are presuming that a piece of the object fell through their roof." What was the 'fireball' spotted over the US? The fireball that caught the attention of people across the southeastern United States is presumed to be from a meteor fragmenting in the sky, according to meteorologists and other experts. Where was the 'fireball' meteorite seen in US? The American Meteor Society received nearly 150 reports of a meteor bright enough to be seen streaking across the midday sky beginning around noon local time Thursday, June 26. Most of the reports were from Georgia and South Carolina, but a few witnessed the object in Florida, Alabama, Tennessee and North Carolina. There have been many reports of a #fireball streaking across the southeastern U.S. this afternoon! The Geostationary Lightning Mapper (#GLM) on @NOAA's #GOES satellites can occasionally detect these bright meteors (aka #bolides) when they pass through the the… The National Weather Service office in Charleston said on Facebook that its satellite-based, lightning-detection system showed 'a streak within cloud free sky' over Gasburg, Virginia, near the state's border with North Carolina. What is a fireball? How rare is a 'fireball' meteor? Rocks in space are known as meteoroids. If those space rocks enter Earth's atmosphere, they become meteors that streak across the sky in events colloquially referred to as "shooting stars." Meteors – or fragments of them – that survive their atmospheric trip and land on the surface without burning up become meteorites, according to NASA. What many witnessed recently was a very bright meteor known as a fireball. It's relatively rare for fireballs to be sighted on Earth, especially during the daytime, as the objects generally have to be at least as bright as Venus to be visible to the naked eye, according to the American Meteor Society.

Fireball over Georgia sparks meteorite investigation after debris damages home
A bright fireball that lit up the sky over Georgia and surrounding Southeastern states on June 26, 2025, is under investigation as officials examine whether it was caused by a meteorite. The object may have caused property damage in McDonough, Georgia, where debris reportedly fell through the roof of a home. The fireball appeared around 12:20 p.m. and was seen from Macon, Georgia, to Upstate South Carolina. More than 100 eyewitnesses filed reports with the American Meteor Society, describing a sudden flash, ground tremors, and a loud boom. Radar imagery and lightning sensors from NOAA's GOES satellites picked up signatures consistent with a meteor entering Earth's atmosphere. A Columbia County resident recorded a video of the fireball, while another in Henry County reported a rock crashing into their home, piercing the roof and damaging the floor. BREAKING: Apparently bits off the fireball/meteor hit the roof of a home in Henry County, Georgia... 📷 WSB-TV/11Alive — Volcaholic 🌋 (@volcaholic1) June 26, 2025 Although residents initially suspected an earthquake, the U.S. Geological Survey confirmed no seismic activity occurred. Experts now believe the shaking was due to a sonic boom from the object's high-speed entry. Meteorologists also identified a debris field near Blacksville, Georgia, just south of the Home Depot distribution center off Highway 20. South Carolina authorities in Anderson, Greenville, and Spartanburg counties are also investigating potential impact sites. The exact nature of the object—whether a meteorite or space debris—remains unconfirmed. Officials urge anyone with footage or images to submit them to local news outlets. Investigations are ongoing.

Artificial intelligence among new tech shaping forecasts during 2025 hurricane season
MIAMI – In light of hurricane season starting this weekend, NOAA's National Hurricane Center (NHC) provided a sneak peek into how the agency has updated its approach to forecasting hurricanes, particularly by using new technology. NHC Director Michael Brennan told FOX Weather Hurricane Specialist Bryan Norcross on Friday that some of those changes include upgrading NOAA's hurricane analysis and forecast system hurricane models this summer. They will also apply updates to how his team forecasts rapid intensification, which is when a tropical cyclone's maximum sustained winds increase by at least 35 mph in a 24-hour period. Brennan said progress has been made in this field since Katrina hit in August 2005, allowing forecasters to improve their understanding of how intensity works. Another update to the NHC's forecasting includes using a new Geostationary Operational Environmental Satellite, or GOES. Brennan noted how the satellite, which has been parked over the Atlantic and the eastern U.S., is already being used as the primary tool for monitoring the tropics, or the area of the Atlantic where tropical storms form. Noaa's Goes-19 Weather Satellite Begins Operations In Orbit Perhaps one of the newest types of technology the NHC will use in developing its forecasts is artificial intelligence (AI). Traditionally, some of the more accurate forecasts are developed by taking the so-called "averages" of multiple weather models. This year, meteorologists at the NHC will begin to test models produced by AI in the context of traditional modeling when they build their forecasts. "They're (AI) not going to be part of our official sort of consensus or blended models this year, but we may make some additional ones on the side that we're going to test out and see how they do and perform," Brennan said. He noted how AI might especially show a lot of promise when it comes to forecasting the path of a hurricane. However, he looks at that potential with a keen eye. "It's important for us to look at it ourselves, do our own evaluation and see how it fits in," he said. NOAA said this hurricane season is expected to see 13-19 named storms, or storms with maximum sustained winds strong enough to classify them as either tropical storms or hurricanes. In fact, NOAA predicts that 6-10 of those named storms will be hurricanes, and about half of those are expected to become major hurricanes with sustained winds of at least 111 mph. 2025 Atlantic Hurricane Season Outlook FOX Weather will premiere two specials on the FOX Weather channel and FOX Weather app as the U.S. kicks off hurricane season. The first special will be "Hurricane HQ: Eye on the Season," which will air on Sunday at noon ET. In this special, FOX Weather Meteorologist Ian Oliver revisits hard-hit communities from last year's deadly storms, while Hurricane Specialist Bryan Norcross breaks down the driving forces behind the season ahead. On Monday at 9 a.m. ET, Norcross will answer hurricane questions live during a unique, interactive hourlong special called "Hurricane HQ&A with Bryan Norcross." How To Watch Fox Weather In addition to the two specials, FOX Weather will also kick off the official start of the 2025 hurricane season with "Hurricane HQ Week." The network's meteorologists will share the latest predictions, heartfelt stories of survival and talk with those still rebuilding from last year's destructive storms.

Florida hurricane season: Science behind satellite images of tropical storm sizes
To us here on Earth, most of us never give a second thought to satellites, which may appear like small shining stars among many in the night sky – if they appear at all. But as hurricane season approaches in Florida, satellites will get a detailed view of our planet from far away. From all the way up in orbit, the spacecrafts provide a critical tool for scientists and other officials to monitor the development of tropical storms and keep the public informed about incoming danger. While hurricane season doesn't begin until June 1, the National Oceanic and Atmospheric Administration (NOAA) has already started its daily tropical outlooks – highlighting areas showing potential for tropical development within about a week's time. That means its National Hurricane Center will turn to its fleet of orbital satellites for data, which can keep an eye on tropical storms much more effectively than land-based observations alone. First introduced in 1975, geostationary satellites have become a standard instrument for weather forecasting, especially during the Atlantic hurricane season, win runs June 1 to Nov. 30 every year. Technology has greatly improved in the decades since, enabling the satellites to relay data faster back to Earth while transmitting better quality images and storm detection details. Geostationary satellites orbit Earth at a speed allowing them to stay fixed over the same area of the planet so they can continuously monitor a tropical storm and its development. NOAA is responsible for the GOES satellites that are constantly monitoring Earth for weather threats. The latest among them, the GOES-U satellite, launched in June 2024 from Kennedy Space Center near Cape Canaveral, Florida. The GOES-U satellite – Geostationary Operational Environmental Satellite U – is designed to not only enable earlier storm detection, but also give forecasters more time to warn the public. Images from the GOES satellites reach NOAA at about five-minute intervals. But the next generation of satellites the agency is planning − GeoXO − will see the forecasting capabilities improve even further. The GOES-U satellite was due to become operational in spring 2025 after undergoing a test period in fall 2024. The last in NOAA's current series of satellites known as GOES-R − named after the first satellite of the series − the satellite is improved over previous iterations to detect not only a weather system's structure but its exact location. Those capabilities should prove crucial during hurricane season, when GOES-U and other satellites will play a critical role in Florida's early warning system, Michael Brennan, director of the NOAA National Hurricane Center in Miami, previously told FLORIDA TODAY, a USA TODAY Network newspaper. "Satellite imagery is our first line of defense against hurricanes," Brennan said. "It's how we monitor systems that develop, it's how we estimate how strong they are before we can fly an aircraft into them." It's not just satellites that can monitor hurricanes from high in the sky. NASA's International Space Station, which orbits Earth from around 250 miles high, also routinely captures imagery of tropical storms and hurricanes that provide a striking bird's-eye view. For instance, as Hurricane Milton moved in on Florida in October 2024, the U.S space agency released photos and a timelapse video showing the eye of the storm as it churned and swirled its way toward the coast. External cameras on the International Space Station first captured a glimpse of the gathering tempest Oct. 7 while orbiting above Florida. At the time, the Category 5 storm was packing winds of 175 mph as it moved across the Gulf of Mexico, later renamed by the U.S. government as the Gulf of America.

How a 'mudball' meteorite survived space to land in the jungles of Central America
When you buy through links on our articles, Future and its syndication partners may earn a commission. The pieces of a meteorite that fell in Costa Rica in 2019 are so unusual that scientists believe it had moved through space relatively unscathed — that is, until it encountered our planet. This is in stark contrast to other typical meteorites that show the wounds of having been in numerous collisions before reaching Earth. The meteorites were recovered from near the Costa Rican town of Aguas Zarcas, and are of a type referred to as 'mudballs', in the sense that they contain water-rich minerals. The findings have resulted in a reappraisal of these so-called mudball meteorites. It had been assumed that their high content of water-rich minerals would make them structurally weaker than other types of meteorites, rendering them more susceptible to damage or burning. But, "Apparently, [the presence of water-rich minerals] … does not mean they are weak," said Peter Jenniskens, a meteor astronomer from the SETI Institute and NASA Ames Research Center in California, in a statement. Scientists say the discovery rivals one of the largest discoveries of meteorites nearly 50 years prior. "Twenty-seven kilograms [60lbs] of rocks were recovered, making this the largest fall of its kind since similar meteorites fell near Murchison in Australia in 1969," said Jenniskens. The Murchison meteorite fall occurred just two months after the Apollo 11 mission. The recovered pieces showed that evidence of having been altered by liquid water on its parent body before an impact smashed apart that parent body and sent the Murchison and, later, the Aguas Zarcas meteoroids spinning into space. (Meteoroids are what we call meteorites when they are in space.) Video camera footage shows the 2019 mudball meteor entering the atmosphere from the west-north-west direction over Costa Rica at a steep, almost vertical angle of 81 degrees, and at a velocity of 9 miles (14.6 kilometers) per second. This steep angle allowed the meteor passed through less of Earth's atmosphere than it would have if it had approached on a shallower angle. That means more of the original meteoroid survived the fiery passage through the sky above Costa Rica. Based on the incoming meteor's trajectory, "We can tell that this object came from a larger asteroid low in the asteroid belt, likely from its outer regions," said Jenniskens. As it entered Earth's atmosphere, the rocky body is estimated to have been about 23.6 inches (60 centimeters) across. Friction with the atmosphere generated heat that melted its surface, stripping away much of the rock in a process known as ablation as it began to burn up. "It penetrated deep into Earth's atmosphere, until the surviving mass shattered at 15.5 miles (25 kilometers) above the Earth's surface, where it produced a bright flash that was detected by satellites in orbit," said Jenniskens. Those satellites were the Geostationary Operational Environment Satellites (GOES) 16 and 17 and their lightning detectors, which are Earth-observing satellites operated by NASA and the National Oceanic and Atmospheric Administration (NOAO). The fragments scattered themselves across the soft ground of Costa Rican jungle and grasslands, where they were subsequently found by meteorite hunters and volunteers. But the meteorites had a slightly unusual appearance. "The Aguas Zarcas fall produced an amazing selection of fusion-crusted stones with a wide range of shapes," said meteor scientist Laurence Garvie of the Buseck Center for Meteorite Studies at Arizona State University. "Some stones have a beautiful blue iridescence to the fusion crust." The fusion crust is the glassy, melted surface of a meteorite after it has endured ablation. Usually, meteorites have some flat sides, where they have broken apart as the result of stress fractures in the original meteoroid that were placed there by collisions in space with other meteoroids. The rounded rather than flat shapes of the Aguas Zarcas meteorites suggested that the meteoroid had travelled through space relatively unscathed after being blasted off its parent body. It has even been possible to calculate how long ago that was. Exposure to cosmic rays alters the composition of a meteoroid, so the degree of alteration tells us how long a meteoroid has been in space after breaking off its parent body. "The last collision experienced by this rock was two million years ago," said cosmochemist Kees Welton of UC Berkeley, who led this part of the study. "After getting loose, it took two million years to hit the tiny target of Earth, all the time avoiding getting cracked," added Jenniskens. This seems surprisingly recent, given the 4.6-billion-year history of the solar system. "We know of other Murchison-like meteorites that broke off at approximately the same time [as Murchison], and likely in the same event, but most broke much more recently," said Welton, with the Aguas Zarcas meteorites exemplifying the point. RELATED STORIES: — What are meteorites? — Watch (and hear!) a meteorite impact on doorbell camera video in a world 1st — Meteorites could have brought all 5 genetic 'letters' of DNA to early Earth Perhaps it is appropriate that the last word goes to Gerado Soto of the University of Costa Rica in San José, who draws similarities with the Murchison meteorite fall and its closeness in time to Apollo 11. "The fall of Aguas Zarcas was huge news in the country. No other fireball was as widely reported and then recovered as stones on the ground in Costa Rica in the past 150 years," he said. "The recovery of Aguas Zarcas [meteorites], too, was a small step for man, but a giant leap in meteoritics." The findings were published on March 29 in the journal Meteoritics & Planetary Science.
